Abstract This paper analyzes, from Immanuel Wallerstein's Analysis of the World – System, an introduction, the emergence of the modern world – system, the permanence of the colonial logic in the modern capitalist world-system from a decolonial approach. It examines how the center – periphery structure has determined the economic, political and epistemic dynamics at the global level. Through this approach we study how coloniality has influenced the construction of knowledge. It also analyzes the impact of this structure on the recognition of States and the negotiation of international treaties, showing how Western power has conditioned the legitimacy and autonomy of peripheral nations. It also addresses the persistence of the center-periphery logic in local relations, as well as in gender and racial inequality, highlighting the role of anti-systemic movements in the struggle against these structures. It concludes that, although colonial dynamics continue to operate through debt, extractivism and the imposition of political models, decolonial perspectives offer tools to make visible and resist them. Introduction This paper will analyze the dynamics of the current international system based on the work “World-Systems Analysis: An Introduction – The Rise of the Modern World-System” by Immanuel Wallerstein. In it, Wallerstein (2005) argues that the modern capitalist world-system has structured the global order since the 16th century, consolidating a hierarchical division between the center and the periphery. This division has not only shaped economic and political dynamics but has also established patterns of domination and dependency that persist to this day. The colonial expansion of European powers not only guaranteed access to resources and markets but also legitimized a system of exploitation based on racism and the hierarchization of colonized peoples. The decolonial perspective of Walter Mignolo (2013) will be adopted, which posits that this is a political and epistemic project aimed at dismantling the colonial matrix of power that sustains Western modernity. From this framework, the article will analyze how colonial logic continues to operate in the capitalist world-system through the economic and political subordination of the peripheries. It will also examine the impact of the colonial worldview on knowledge production during the 18th and 19th centuries, as well as the reproduction of the center–periphery dynamic in the recognition of states during the 20th century and in the negotiation of international treaties during the 21st century. Likewise, it will address how this dynamic manifests not only internationally but also within local structures, perpetuating inequalities expressed in labor, gender, and racial relations today. This work seeks to provide a critical perspective on the persistence of colonial logic in the modern capitalist world-system, emphasizing the need to rethink power structures from a decolonial perspective that makes visible and vindicates the subaltern voices that have been historically silenced. Development Colonial Logic in the Capitalist World-System In his work “World-Systems Analysis: An Introduction – The Rise of the Modern World-System”, Wallerstein seeks to understand the structure and dynamics of the world-system, taking the 16th century as the starting point —a period when the conquests of the territories we now know as the Americas took place. The colonial period clearly illustrates the core–periphery dynamic (Wallerstein, 2005), as the Spanish, British, and Portuguese empires engaged in the extraction of resources from their colonies, while colonized peoples endured oppression and racism to which they would be condemned for centuries. This oppression brought significant benefits to the modern world-system, as it enabled massive capital accumulation — but exclusively in the core. This was because the colonial process built peripheral economies around the needs of the core, forcing them into subordination to the interests of the global market, generating dependency and underdevelopment. Quijano and Wallerstein (1992) argue that “[…] ethnicity was the inevitable cultural consequence of coloniality. It delineated the social boundaries corresponding to the division of labor” (p. 585). Due to the colonial period, the modern capitalist world-system laid its foundations and strengthened its market-based economic model through racism and hierarchization — circumstances that have legitimized the exploitation and domination of non-European peoples throughout history. Control over the resources of peripheral states by core states has endured to this day, along with the imposition of Western production and consumption models that perpetuate inequality. The colonial period’s greatest legacy remains systemic violence and subalternity. On this basis, it is important to analyze this work from a decolonial perspective. For Walter Mignolo (2013), “decoloniality is not a concept, but a practice and a political, epistemic, and ethical project aimed at disengaging from the colonial matrix of power that sustains Western modernity” (p. 21). This perspective also draws on the notion of epistemic subalternity, which refers to the experiences and knowledge of colonized and subaltern peoples that are rendered invisible, devalued, or reduced to particular cases — without being considered an integral part of the world-system (Mora, 2008). Coloniality in the Construction of Knowledge At the end of the 18th century, the modern university emerged, dividing its studies into two faculties: sciences and humanities. In the 19th century, another division took place within the humanities, opening the space for the study of social sciences, which would later also be split — on one side, those leaning toward scientism, and on the other, toward the humanistic approach. This led to the creation of new disciplines: economics, political science, and sociology (Wallerstein, 2005). These new sciences built their worldview and knowledge construction from a Eurocentric and colonialist perspective, thus assigning labels to peoples different from their own. These new sciences categorized the study of the world’s peoples into three groups. First, civilized peoples — Western nations, considered as such because they believed their social and political organization systems were the most advanced. Second, the high civilizations — India, China, Persia, and the Arab world — classified in this way because they possessed writing, religion, language, and customs. They were regarded as civilized peoples but not modern, under the previously mentioned concept. This category gave rise to orientalist scholars, with a Eurocentric and exoticizing view. Finally, the so-called primitive peoples — those who, from the colonial perspective, lacked writing, religion, language, and customs. This perception of the “uncivilized other” was used to justify colonial processes in the periphery, which even today enable the reproduction of exploitative and racist practices. Segregation in the construction of knowledge, imbued with colonial and Eurocentric thought, is based on criticizing the behavior of these peoples and on what should be changed about them (Zapata, 2008). The Eurocentric conception asserts categorically that the modus vivendi of these peoples is not appropriate according to Western standards. Although this way of thinking has evolved over time, its essence remains the same and has led Western countries to grant themselves the power to change the way of life of these peoples through invasions, neocolonial processes, and violent interventions via military force or economic interference. The Center and the Periphery in the Recognition of States As previously mentioned, Europe established a correspondence between modernity and the West; this includes the institution of the nation-state as its derived product (Zapata, 2008). From the Eurocentric perspective, for civilizations to be considered nation-states, they must possess four characteristics: territory, population, government, and sovereignty. In Public International Law, sovereign states are the main subjects of international relations, and for a state to be recognized as such, it must be acknowledged by the majority of states that are part of the international system. The center–periphery concept operates both economically and politically, which can be observed when a new state seeks recognition from members of the international system. The recognition granted by a state from the center carries more weight than that from the periphery, since states in the center, with greater political and economic capacity, influence the decisions of their allies — both within the center and the periphery. This need for state recognition has been extremely beneficial for the modern capitalist world-system, as political and economic interdependence, along with the perpetuation of power in the countries of the center — particularly those belonging to the West — ensures that they act, whether in matters of state recognition, political agendas, or economic issues, entirely to their own advantage, disregarding the interests of “the other.” From a decolonial perspective, state recognition is a Western construct designed to maintain control over who meets the imposed criteria to belong to the Eurocentric international system. These criteria clearly do not align with the social organization of all non-Western civilizations but were conceived in such a way as to subordinate them to the needs of the world-system, which inevitably serves the interests of Western core states. This can be exemplified by the case of Taiwan. In 1971, the Kuomintang lost recognition from the government of mainland China, and starting in 1985, Taiwan’s government sought to strengthen diplomatic relations with states that already recognized it and to develop relations with those that did not, with the aim of obtaining their approval (Connelly, 2014). Despite the passage of time, recognition of Taiwan as a state by core countries seems inconvenient for them, likely due to the ongoing political dispute between Taiwan and China. As a result, only 14 peripheral states recognize it as such. Despite this, the Northeast Asian country maintains unofficial relations with 47 states and the European Union, for purely economic reasons. The Modern Capitalist World-System in International Treaties It is worth mentioning that the idea of the center–periphery permeates the negotiation of international agreements. As mentioned earlier, the so-called “primitive peoples” were civilizations that, from the Eurocentric perspective of knowledge, lacked writing, religion, languages, or customs. This idea persisted into the 20th century, as reflected in the Statute of the International Court of Justice, which in Chapter II, Article 38, states that “the Court, whose function is to decide in accordance with international law such disputes as are submitted to it, shall apply: […] the general principles of law recognized by civilized nations” (UN, 1945). The Eurocentric conception of a civilized nation in the postwar period was based on the type of government existing in each state. Thus, countries without a democratic political system were not considered civilized nations. This conception forced nations not to determine their own system of government, but rather to adhere to the one imposed by the Western international system in order to be accepted, disregarding their customs and traditions. A more current example of the imposition of Eurocentric ideas on systems of government is the signing of the Free Trade Agreement between the European Union and Mexico in 2000. Ratification of the trade agreement was conditioned on what they called the “democratic clause.” The agreement was not ratified by the Italian government until July 3 of that year, when the presidential elections resulted in the victory of Vicente Fox (Villegas, 2001). On the same day, the European Commission’s spokesperson, Gunnar Wiegand, said in his press release: “A historic vote has taken place in Mexico. The Commission congratulates the Mexican people for exercising their democratic rights in such a mature and exemplary manner” (Caracol Radio, 2000). The spokesperson’s mention of the Mexican people’s maturity refers to the notion that, in the past, the exercise of democracy had not possessed this quality — an observation made from a paternalistic and Eurocentric perspective. Had the election results been different, Mexico could have faced the possibility of the European Union “imposing sanctions as a reaction to the verification of interruptions in democratic processes, which, in addition to affecting development, constitute a threat to international peace and security” (Cordero Galdós, 2002, p. 128). The criticism of the imposition of the “democratic clause” centers on the recurring practice of requiring peripheral states to adapt to the political ideologies and economic needs of the core. The Reproduction of the Center–Periphery Dynamic at the Local Level As mentioned in the development of this work, the effects of colonialism persist across all systems and subsystems through the coloniality of power, knowledge, and being, the latter of which will be addressed later. This is manifested in global inequalities, the exploitation of natural resources in peripheral countries, and the persistence of racist and Eurocentric power structures. From Wallerstein’s perspective, the world-system is a historical structure which, although in constant transformation, reproduces power relations and inequalities over time through the domination of the core and the exploitation of the peripheries (Wallerstein, 2005). Thus, the world-system has evolved in several ways; one of these is the introduction of the term semi-periphery into the analysis. During the colonial period, there were only core and peripheral nations. Over the centuries, however, semi-peripheral states have emerged — nations that not only extract raw materials or engage in manufacturing but also have the capacity to produce cutting-edge technology (Wallerstein, 2005). This positions them in a more privileged place than peripheral countries in the international system. Yet, despite appearing to have overcome the systemic oppression that once kept them in the periphery, the colonial mindset within their institutions perpetuates their subordination to the core. Good examples of semi-peripheral states in Latin America are Mexico and Brazil. Both countries were victims of the exploitation and systemic violence of colonialism. This shaped the development of their societies and economies for centuries. Even after achieving independence and building productive and economic systems that placed them in the semi-periphery, their economic progress was built on a legacy of oppression and racism that continues to reproduce the abuses described. In this way, the concept of core and periphery permeates social and family subsystems. This can be observed in labor relations, where capitalists depend on the core–periphery or superior–subordinate relationship to sustain the production model. It is also evident in social relations, which Wallerstein refers to as anti-systemic movements. Society perpetuates the core–periphery principle by placing women and racialized communities in the periphery, while men — especially white men with power — occupy the core. Anti-systemic movements paved the way for the struggle against these inequalities, giving rise, for example, to feminist and Indigenous movements. These have led to the development of theoretical perspectives such as decolonial feminism, which adds analytical variables to the decolonial perspective. According to Yuderkys Espinosa, it emerges from “[…] a subaltern, non-hegemonic voice […] anti-colonial, anti-imperialist, anti-capitalist. […] Its aim is to question and oppose an imperial and racist rationale” (Barroso, 2014, p. 2). Conclusions The modern capitalist world-system has managed to sustain and expand itself thanks to colonial structures that, far from disappearing with decolonization processes, have mutated and perpetuated dynamics of domination and dependence. As discussed, the core–periphery logic has been key to the organization of the international system, not only in economic terms but also in the construction of knowledge, the legitimization of states, the negotiation of international agreements, and the imposition of political and social models from Western hegemony. The colonial legacy remains in the structural subordination of peripheral economies to the interests of the core, the imposition of international norms that favor core countries, and the persistence of racialized and gender-based inequalities within peripheral states themselves. This scheme has not only ensured capital accumulation in the core but has also limited the self-determination of historically colonized peoples, while normalizing their exclusion from political, economic, and epistemic spheres. At the international level, neocolonialism operates through mechanisms such as external debt, unequal trade agreements, and political interference in the internal affairs of peripheral states. In addition, extractivism and territorial dispossession continue to reproduce colonial logics, affecting both peripheral countries and Indigenous communities as well as other historically marginalized groups. In this sense, the modern capitalist world-system not only perpetuates economic exploitation but also reinforces power structures based on racism, sexism, and subalternity. However, as decolonial perspectives point out, the coloniality of power is not an immutable phenomenon. This approach questions the structures of power and knowledge inherited from colonization, seeking to deconstruct Eurocentric discourses and make visible the voices and experiences of the subaltern. Anti-systemic movements have sought to challenge these structures, reclaiming the agency of subaltern peoples and promoting the construction of alternatives that confront the colonial matrix of power. Particularly, decolonial feminism has emerged as a key critique of the intersection between patriarchy and coloniality, showing how women — especially racialized women — have been relegated to the periphery of the system. Thus, analyzing the world-system from a decolonial perspective allows us not only to understand the continuity of structures of domination but also to recognize the spaces of resistance and contestation that emerge within it. In conclusion, the decolonial perspective enables us to rethink the modern world-system from a critical standpoint, recognizing structural inequalities and the need to transform the power dynamics that perpetuate the domination of the core over the periphery. Decolonialism makes it possible to redefine notions of progress, development, and modernity from a perspective free from colonial stereotypes and hierarchies, recognizing the diversity of knowledge and worldviews of Indigenous peoples. It seeks to decentralize power by rethinking and decolonizing power relations between the core and the periphery, between the state and local communities, aiming for a more equitable distribution of resources and benefits. It is essential to make visible and vindicate the subaltern voices that have been historically silenced, promoting an epistemic and political shift that dismantles the foundations of this system and paves the way for fairer and more inclusive models. References Andrade, V.

The BRICS meeting in Rio on July 6th and 7th gives a snapshot of the great power competition between China and the United States in different regions around the world, including Latin America. China has become the largest trading partner for many countries in Latin America, investing heavily in infrastructure and forging political alliances that further its strategic objectives. For its part, the Trump Administration of the United States issued the statement that those participating countries will face increased tariffs. The statement was the continuation of exercise and assertion of its authority for the past and present century. The positioning of various BRICS members and participating countries is particularly telling of what the great power competition means in the region and also globally. Brazil’s Lula hosted the meeting aiming to showcase its foreign policy leadership, not necessarily antagonizing the West. Russia is still going through the war in Ukraine, and Putin attended only online. India’s Modi was present as well as Ramaphosa from South Africa. No show of Xi Jinping was notable, although Premier Li Qiang was attending. Besides the BRICS core, other countries also showed promotion of their interests. Iran, for one, joined the group in 2024 and sent a ministerial level delegation to rebuke recent strikes on Iran. As the United States appears to be pulling back from its traditional leadership role in the world, China is seizing the opportunity to expand its influence and reshape global dynamics. Through a combination of state-driven development policies and active international engagement, Beijing has positioned itself as a major player in the Global South, extending its reach beyond Asia to regions such as Africa and Latin America. China’s increasing presence in the region has been mainly driven by the Belt and Road Initiative (BRI) and a surge in trade volumes, marking a major shift in the region’s economic landscape. Many experts point to China’s use of “infrastructure diplomacy”—financing ambitious, strategic infrastructure projects across the region—as a key factor in this rise. The numbers tell a compelling story. Trade data from the World Bank (Figure 1) shows that in the past ten years, China has overtaken the United States as the leading trading partner for much of the region, upending a dynamic that had held steady since the early 2000s. Beyond trade, China’s influence deepens through the 22 countries in Latin America and the Caribbean that have joined the Belt and Road Initiative. Chinese loans have poured in, funding major energy, infrastructure, and development projects that have reshaped local economies. China’s push isn’t just economic—it’s political too. Beijing has taken steps to strengthen cultural ties, increase academic exchanges and boost tourism in Latin America, including waiving visa requirements for travelers from some countries. This multi-faceted approach highlights China’s pragmatic mix of economic self-interest and strategic diplomacy as it works to secure resources, expand markets, and bolster its global standing. On the other hand, the United States has long been a strategic ally and key trading partner for Latin America. Agencies like USAID have funneled millions of dollars into economic and military initiatives across the region. With the recent changes in the aid policy, immigration policy, and tariff policy, Washington’s recalibration of its foreign policy are transforming the geopolitical balance in Latin America and the Caribbean. As both powers deploy their strategies — from deepening economic ties to defending national interests — the decisions of Latin American states remain critical in shaping their alignments with global powers. The ultimate outcome is still up in the air, but one thing is clear: power in the region is actively being renegotiated. The diverging approaches from China and the US have set the stage for a broader reconfiguration of power in Latin America and the Caribbean. Yet, it’s essential to recognize that each country’s internal decisions and policies also play a critical role in shaping this shifting landscape. Colombia provides a case in point. Historically, it has maintained close diplomatic ties with the United States while keeping China at arm’s length. Unlike countries like Brazil, Argentina, and Peru, Colombia has received relatively little Chinese infrastructure investment. However, with the election of president Gustavo Petro—the first left-wing president in the country’s history—Colombia has taken decisive steps to strengthen its relationship with China, presenting new challenges for the United States to maintain its strategic foothold in the country. We observe – both on political and economic dimensions – that the changes in China’s strategy, coupled with Colombia’s domestic policies, have reduced the country’s dependence on the US while increasing its desire to integrate with China. Politically, Colombia and the United States have long enjoyed a strong diplomatic relationship, as reflected in their shared memberships in international organizations, high-level dialogues, and multiple bilateral agreements. However, diplomatic tensions have emerged in recent years. Disputes between the two leaders, the change of course of USAID, and a significant drop in new bilateral agreements over the past four years have contributed to a shift in this traditionally stable partnership. Against this backdrop, diplomatic ties between China and Colombia have strengthened. In 2023 alone, both countries signed 12 cooperation agreements in trade, technology, and economic development, upgraded their relationship to a strategic partnership, and Colombia’s entry into the Belt and Road Initiative during recent China – CELAC Forum in May. Colombia also joined the BRICS New Development Bank a few weeks after that Forum. Economically, the US has traditionally been Colombia’s largest trading partner, backed by a free trade agreement and significant investment. Yet, in recent years, the share of US trade has steadily declined, while China’s footprint has grown (see figure 1). Although there’s no formal trade agreement, ties have strengthened during the current administration, including the opening of a Buenaventura-Shanghai trade route in 2025. Additionally, China’s “infrastructural diplomacy” has significantly grown: over 100 Chinese companies now operate in Colombia, and major infrastructure projects like Bogotá’s Metro Line 1 and the Regiotram are underway, along with investments in mobility, technology, and health. Latin America, and Colombia in particular, finds itself at the center of a geopolitical tug-of-war with China’s calculated investments and the US’s shifting policies. While Beijing leverages trade, infrastructure, and cultural diplomacy to expand its influence, Washington’s recalibration of its foreign policy leaves room for new alliances and opportunities. Our analysis shows that power reconfiguration is not merely a product of external rivalry. It is driven by the choices each Latin American nation makes. As Colombia’s case demonstrates, the region’s destiny hinges not just on global superpowers, but on its own internal political decisions and developments. The coming years will test how Latin America navigates these shifting currents. Disclaimer This article was made possible in part by a grant from the Carnegie Corporation of New York (G-PS-24-62004, Small State Statecraft and Realignment).

ABSTRACT  This paper examines de-dollarization as a geopolitical industrial policy within the BRICS framework and its implications for Cuba, Venezuela, and Argentina. De-dollarization, a process aimed at reducing reliance on the US dollar, has gained momentum among BRICS nations as a response to economic sanctions, monetary sovereignty concerns, and external financial shocks, particularly following the 2008 global financial crisis. For Cuba and Venezuela, de-dollarization is necessary due to US sanctions, pushing them toward alternative  financial  mechanisms  through  BRICS  partnerships. Cuba’s  possible  de-dollarization  follows  increased ties with Russia, China, and Iran. Regarding Venezuela, despite its partial dollarization, Caracas seeks  to  strengthen  non-dollar  transactions  through  oil  trade. In  contrast,  under  President  Javier  Milei,  Argentina  has  rejected  BRICS  and  continues  to  debate  dollarization,  reflecting  the  country’s  historical  and economic ties to the US dollar. The study highlights that de-dollarization is a State-led, multilateral process influenced by external economic conditions and geopolitical alignments. While Cuba and Venezuela actively integrate with BRICS to reduce dollar dependence, Argentina’s approach remains uncertain, shaped by ideological and financial considerations. Keywords: De-dollarization, BRICS, Cuba, Venezuela, Argentina INTRODUCTION De-dollarization is almost a synonym of BRICS. The reduction  of  US  dollar  dominance  and  the  consequential dependence on it represent critical stakes for BRICS countries. Nonetheless, there are nuances and differences amongst BRICS members on monetary policies. Since the first summits (2009–2010), BRICS  asserted  the  Global  South’s  need  to  prioritize  trade  in  domestic  currency  and  refrain  from  US  dollar  pegging. For  initial  members  like  China  and  Russia,  as  well  as  newly  associated  countries  such  as  Iran  and  Cuba,  Western  sanctions  are  the  main  driver  for  de-dollarization. Instead,  for  Brazil,  India, and the majority of most recent BRICS partners  (primarily  from  Africa  and  Southeast  Asia),  de-dollarization  means  enhancing  their  monetary sovereignty,  fostering  domestic  currencies’  value,  and  avoiding  depending  on  US  institutions:  Treasury and Federal Reserve. De-dollarization pertains to  monetary  and  public  policies. Therefore,  it  is  a  state-led process. For this reason, it might be considered an industrial policy. It is necessary to outline that this article adopts the term geopolitical industrial  policy  for  a  State-led  economic  strategy  that,  unlike  inward-oriented  monetary  or  financial  policies, is deeply intertwined with the outward-looking dimension of foreign policy. Hence,  this  work  examines  de-dollarization  as  a  geopolitical  industrial  policy  within  the  BRICS  framework  and  its  implications  for  Cuba,  Venezuela,  and  Argentina. De-dollarization,  a  process  aimed  at  reducing  reliance  on  the  US  dollar,  has  gained momentum  among  BRICS  nations  as  a  response  to economic sanctions, monetary sovereignty concerns,  and  external  financial  shocks,  particularly  following the 2008 global financial crisis. For Cuba and  Venezuela,  de-dollarization  is  necessary  due  to  US  sanctions,  pushing  them  toward  alternative  financial  mechanisms  through  BRICS  partnerships. Cuba’s  possible  de-dollarization  follows  increased  ties  with  Russia,  China,  and  Iran. Regarding  Venezuela, despite its partial dollarization, Caracas seeks to  strengthen  non-dollar  transactions  through  oil  trade. In  contrast,  under  President  Javier  Milei,  Argentina has rejected BRICS and continues to debate dollarization, reflecting the country’s historical and economic ties to the US dollar. The study highlights that de-dollarization is a State-led, multilateral process  influenced  by  external  economic  conditions  and geopolitical alignments. While Cuba and Venezuela actively integrate with BRICS to reduce dollar dependence,  Argentina’s  approach  remains  uncertain,  shaped  by  ideological  and  financial  considerations. It is undebatable that there are differences between usual industrial policies and de-dollarization. Indus-trial policies look inward, are fashioned upon domes-tic  matters,  and  contradict, court,  multilateral  efforts. De-dollarization  is  a  geopolitical  industrial  policy that looks outward, focusing on the role of a given country in the world economy. Without multilateralism, a State pursuing de-dollarization would quickly become a pariah. As a geopolitical industrial policy,  de-dollarization  owes  its  rationale  to  external  shocks. It  is  safe  to  define  de-dollarization  as  exogenously  motivated. The  2008  global  financial  crisis (GFC) represented the critical external shock for  BRICS  members  to  escalate  their  de-dollarization objectives: “[E]specially  since  the  2008  global  financial  crisis,  central banks of many countries have been trying to diversify their portfolios to shift away from the US dollar through liquidating holdings of US Treasuries and increasing other assets including the euro, yen, renminbi and gold.” (Li, 2023, p. 9).  The 21st century wrought incentives to de-dollarization that finally sparked because of the GFC. However,  the  mainstream  doubts  surrounding  de-dollarization involve its feasibility. There are no tools to objectively  measure  the  status  of  de-dollarization  or its future outcomes. Notwithstanding limitations, de-dollarization  is  increasingly  attracting  Global  South economies. Specifically looking at Latin America,  this  work  outlines  how  de-dollarization  becomes  an  obligation  for  sanctioned  countries:  Cuba  and  Venezuela. The  two  ALBA  governments  mingled  with  BRICS  for  a  long  time,1  with  Havana  joining the forum in association and Venezuela almost on the same route, stopped by the Brazilian veto in the  Kazan  summit. Cuban  and  Venezuelan  de-dollarization finds in BRICS a multilateral opportunity.  The third country examined is Argentina since the government  of  Javier  Milei  refused  to  enter  BRICS  and  continuously  flirted  with  dollarizing  the  economy. From President Menem’s pegging to the US dollar (uno a uno) to the 2001 Corralito, Argentina’s recent economic history inevitably rests on currency issues (IMF, 2003). Unlike Venezuela, and on the contrary of Cuba (which is not part of the IMF), Argentina’s economic policies intertwine with Bretton Woods  institutions. That  might  be  the  reason  why  neoliberal Argentinian economists found in dollarization  a  solution  for  Buenos  Aires  (Cachanosky  et  al., 2023).  1. Force Majeure De-Dollarization for Cuba and Venezuela  Since  1999,  when  Fidel  Castro  and  Hugo  Chávez  coincided, de-dollarization meant an industrial foreign policy to antagonize US hegemony. In Cuba, de-dollarization  is  a  more  difficult  process  than  usual  assumptions  and  certainly  more  challenging  than  in  Venezuela. 2004  marked  the  year  when  the  US  dollar  was  officially  prohibited  on  the Caribbean Island, to reverse the dual currency  system  implemented  since  the  Special  Period  (Herrera  &  Nakatani,  2004). The  extra-territoriality  of  US  sanctions,  affecting  in  their  secondary effect  Cuba’s  trade,  led  Havana  to  a  de-dollarization fashioned upon the path that Deligöz (2024) identified  for  China  and  Russia. Besides  realpolitik  and  geopolitical  strategies,  Cuba’s  association  with  BRICS,  occurred  in  October  2024,  is  the  la-test  effort  to  de-dollarize. Venezuela’s  economic  crises and COVID-19 pushed Cuba into continuous indebtedness to survive, with US dollars reallowed but  still  at  limited  provision  due  to  Washington’s  restrictions  (Luis,  2020). To  give  account  of  its  urgencies,  in  a  few  months,  Havana  moved  from  apparent dollarization to initiatives for de-dollarization, thanks to BRICS. Over the summer, Primer Minister Manuel Marrero enabled USD payments in the  tourist  sector  (Gámez  Torres,  2024)  to  tackle  the balance of payments deficit with liquidity. For  a  country  obliged  to  rapidly  change  industrial  policies,  the  BRICS  opportunity  could  not  be  mis-sed. Cuba’s  reliance  on  Russia,  China,  and  Iran  may  materialize   a   complete   de-dollarization   that   can   favor  BRICS  projects  and  escape  US  sanctions. Of  course, the evident permanence of the bloqueo, regardless  of  who  runs  the  White  House,  is  the  main  driver for Cuba’s de-dollarization. A similar but quite nuanced situation applies to Venezuela as well. From the Bolivarian era inaugurated by President Chávez, de-dollarization  entangled  foreign  policy  objectives  even before US sanctions. The Sucre digital currency was  created  by  the  governments  of  Venezuela  and  Ecuador  as  the  main  ALBA  initiative  to  de-dollarize  commercial  transactions  among  Bolivarian  nations  (Benzi et al., 2016). ALBA-promoted Sucre was analogous to BRICS’ favoring of blockchains and digital currencies, limiting the USD to a reference value for the  bloc’s  transactions  (Mayer,  2024). US  sanctions  on Venezuela’s oil production, sparked under the first Trump Administration, meant a significant remotion of USD-denominated transactions for Caracas. Considering  ALBA’s  slow  progress  and  the  infeasibility  of fully adopting the Sucre, President Maduro had to look at BRICS for solutions. Despite  not  having  diplomatic  relations  with  Washington,  Venezuela  is  still  an  IMF  member. Ladasic points  out  that  “[a]s  Venezuela  joined  the  pack  of  countries  trading  oil  outside  of  USD  and  has  instead priced it in Chinese yuan, BRICS together with Venezuela  already  have  16%  needed  for  IMF  veto  power to use in a crisis” (2017, p. 100). The rentier characterization of the Venezuelan economy and its dependency  on  oil  exports  make  de-dollarization  a necessity. As per Cuba, unilateral policies are not enough. Venezuela’s  outcry  merged  with  inflation,  the  devaluation  of  the  bolívar,  and  a  paralysis  of  the  Venezuelan  Central  Bank  (BCV)  that  put  total  dollarization on the industrial-public policies’ table (Briceño  et  al.,  2019). Although  the  country  is  still  under  a  sort  of  de  facto  dollarization,  Venezuela’s  economic  resurrection  should  occur  together  with  a  de-dollarization  strategy. Failure  to  enter  BRICS  in the Kazan summit provides a temporary brake to Venezuela’s  de-dollarization,  but  the  prolific  trade  with China, Russia, Iran, and Türkiye will, in all cases, align Venezuela with BRICS policies. 3. Argentina: De-Dollarizing a Passion Economists  were  surely  interested  in  Javier  Milei’s  dollarization  claims. Less  than  a  year  into  his  government,  dollarization  seems  impossible  to  the  libertarian  president. Milei’s  negative  to  BRICS  demonstrates  that  de-dollarization  is  currently  not  considerable  for  Casa  Rosada. Nevertheless,  it  is  relevant to outline that Argentinian academia questioned  the  role  of  the  USD  and  studied  economic  policies  involving  de-dollarization. Corso  and  Sangiácomo (2023), in affiliation with the Central Bank of  Argentina  (BCRA),  argued  that  de-dollarization  might  help  in  relieving  the  extreme  inflation  saw  under  Alberto  Fernández’s  ruling. Other  authors  implied  that  the  Kirchners’  limitations  on  USD  access would lead to a gradual de-dollarization of the economy,  but  with  constraints  particularly  from  a  USD dominated housing market across Latin America  (Luzzi,  2013). If  under  the  Kirchners,  and  with  support of South American left-leaning geopolitics, de-dollarization  could  really  offer  a  pathway  for  the Argentine economy, with Milei that is barely an option. The  Argentine  relation  with  the  USD  does not hold a clear ideological cleavage. Argentinians’ passion for the dollar, as stressed by Bercovich and Rebossio (2013), embraced diverse political figures such as Perón, Aníbal Fernández (a prominent Kirchnerist politician), and Martínez de Hoz. The peso’s continuous  instability  legitimized  the  widespread  informal adoption of the USD, with first insight fore-seeable in the currency devaluation subsequent to the Great Depression (Díaz Alejandro, 1970). There is also a nationalistic meaning behind the peso, whose  national  heroes  imprinted,  from  Belgrano  to  Evita (Moreno Barreneche, 2023), portray a sentimental attachment to the banknotes that Argentinians do not want to erase. In sum, Argentina’s de-dollarization is as difficult as dollarization. Milei’s obsession for US hegemony inserts de-dollarization in a faraway scenario. Moreover,  Donald  Trump’s  victory,  who  promised  high tariffs to countries that unpeg from the USD (Butts,  2024),  constitutes  a  natural  barrier  to  de-dollarization. Its political viability might depend on an eventual Peronist succession to Milei. Argentina’s financial closeness  to  China,  and  a  possible  resume  of  BRICS  talks,  could  indicate  de-dollarization  as  a  future  last  resort. In this sense, de-dollarization within the BRICS framework might help Argentina in solving structural issues: Chronic external debt and dependency on Bretton Woods institutions. CONCLUSIONS De-dollarization is State-led and can be considered a  geopolitical  industrial  policy. Cuba,  Venezuela,  and  Argentina  show  that  de-dollarization  depends  on  geopolitical  calculus  and  economic  considerations. The incentives may be different, ranging from US sanctions to devaluation of the national currency. However,  unlike  dollarization,  de-dollarization  cannot  be  pursued  unilaterally. The  rise  of  BRICS  motivates  Global  South  countries  to  de-dollarize  under its guarantees. For Cuba and Venezuela, the association  with  BRICS  and  the  interdependence  with other sanctioned economies like Russia, China, and Iran, make de-dollarization an opportunity. Argentina’s  relation  with  the  USD  follows  its  turbulent  economic  history. Simultaneously,  there  is  passion  for  dollars and nationalism toward the peso banknotes. In this  context,  even  Milei  showed  that  dollarization  is  in  no way easier that de-dollarization. The currency issues affecting Argentina might not be resolved by neither of the two policies, but a future BRICS collaboration could bring de-dollarization again into the political debate. NOTES1  ALBA  references  the  Alianza  Bolivariana  para  los  Pueblos  de  Nuestra  América,  a  regional  organization  founded  by  Cuba  and  Venezuela,  including Bolivia, Honduras, Nicaragua, and several Caribbean islands.

Over time, the bilateral relationship between Mexico and the United States has gone through multiple stages and transitions, reflecting both moments of collaboration and episodes of deep antagonism. At certain points, both countries have succeeded in consolidating frameworks of cooperation in specific areas, such as the peaceful resolution of the El Chamizal territorial dispute in 1967 or the promotion of academic exchange through the Fulbright-García Robles Scholarship Program. However, this interaction has also been marked by significant conflicts, most notably the war of 1846–1848. This confrontation, whose outcome was unfavorable for Mexico, culminated in the signing of the Treaty of Guadalupe Hidalgo, through which the country was forced to cede more than half of its territory. This episode left a deep imprint on Mexico's collective memory. The shared history thus reveals a complex and constantly evolving dynamic. The geographical proximity between Mexico and the United States, with a land border exceeding 3,000 kilometers, requires both governments to adjust their priorities to respond to shared challenges in areas such as security, trade, investment, migration, and other strategic issues. This border condition generates a constant bilateral dynamic, in which national priorities must be harmonized with bilateral and regional interests. From a theoretical perspective inspired by Robert Keohane and Joseph Nye, Dr. Rafael Velázquez Flores argues that this relationship is configured as an asymmetric and multifaceted interdependence. Within this framework, Mexico seeks to expand its decision-making capacity in an environment characterized by structural power imbalances. For his part, Dr. Jorge Schiavon contends that the bilateral agenda operates within a logic of complex interdependence, in which the dense network of institutions and the multiple economic, social, and political ties restrict the ability of either country to act unilaterally. One of the most evident manifestations of the interdependence that characterizes the North American region was the signing of NAFTA in 1992, which came into effect two years later and was transformed into the USMCA in 2018 following a deep renegotiation process. This economic integration mechanism, though less ambitious than the European Union’s model, has strengthened trade and production ties in the region, generating reciprocal benefits. On one hand, U.S. companies have consolidated preferential access to inputs from Mexico, which has boosted key sectors such as automotive, electronics, and agribusiness. Through stricter rules of origin, the agreement has encouraged greater domestic production of components within the United States, protecting industries in strategic states such as Michigan, Texas, and Ohio. In this context, Mexico became the United States’ main trading partner in 2023, with imports valued at $475 billion, surpassing both China and Canada. On the other hand, Mexico regards the United States as its main trading partner, which as of April 2025 accounted for over 80% of its exports and more than 40% of its total imports. The preferential access established by the USMCA has enabled the Mexican economy to position itself as a strategic supplier of goods and services to the U.S. economy, with particular significance in sectors such as automotive, electronics, manufacturing, and agribusiness. The stricter provisions on rules of origin in the automotive sector have encouraged deeper regional integration, leading plants located in Mexico to expand their role in component production and assembly processes. Although the automotive sector captures a large share of the benefits, other industries have also experienced significant growth. As a result, Mexico has become the United States’ main agricultural supplier and has strengthened its presence in sectors such as pharmaceuticals, chemicals, and capital goods, including machinery, electrical equipment, and computing devices.     As shown in Table 1, the United States and Canada occupy the top two positions as destinations for Mexican exports. Based on data from April 2025, the U.S. market imported nearly $45 billion worth of goods from Mexico. Regarding Mexican imports during the same period, the United States ranked first as Mexico’s main trading partner, exceeding $21 billion, with China in second place at just over $10 billion. In this context, it is worth noting that, as shown in Table 2, Canada ranked 10th as a source of Mexican imports. This scenario highlights that the economic integration between Mexico and the United States goes beyond the exchange of goods: both countries have built an integrated and highly specialized production network that generates millions of jobs while fostering growth in the North American region.     On the issue of migration, Mexico and the United States maintain a deep interdependence that permeates the bilateral agenda not only in socioeconomic matters but also in security-related issues. In 2023, approximately 10.6 million Mexican-born immigrants were legally residing in the United States, representing 23% of the total foreign-born immigrant population. At the same time, according to the Pew Research Center, around 4 million Mexicans were living without legal status — down from a peak of 6.9 million in 2007. Thus, the Mexican presence in the U.S. continues to have a dual impact: it contributes labor and demographic stability to the American economy while also generating a steady flow of remittances and transnational ties that support regional development in Mexico and strengthen binational relations. In fact, the Bank of Mexico estimated that remittances sent from the United States to Mexico exceeded $62 billion in 2024 — far surpassing Mexican exports of petroleum products, which amounted to approximately $30 billion that same year. In the current scenario of complex interdependence between Mexico and the United States, the re-election of Donald Trump has introduced a climate of tension that has weakened traditional channels of bilateral dialogue and cooperation. The Republican administration has replaced structured diplomacy with a rhetoric characterized by threats, misperceptions, and a widespread atmosphere of uncertainty. Although President Trump’s confrontational strategy is not limited to Mexico — as it stems from the narrative that the international community has excessively and asymmetrically taken advantage of its relationship with Washington — his administration has intensified the portrayal of Mexico as a key factor behind various domestic grievances in the United States. Irregular migration, drug trafficking, and the trade imbalance have become recurring issues through which the White House channels internal demands, reinforcing a narrative of confrontation. This dynamic undermines the institutional mechanisms of bilateral understanding and places at risk the progress made in economic cooperation, security, and cross-border governance. Since the beginning of his second term, President Trump has implemented a series of unilateral actions that intensify his restrictive immigration agenda. On the very day of his inauguration, he declared a national emergency at the southern border and signed multiple executive orders that eliminated access to asylum, suspended the refugee resettlement program, and reinstated the “Remain in Mexico” policy. He also delegated border control functions to the Department of Defense and authorized the deployment of the military and National Guard to perform tasks traditionally carried out by civilian agencies. Through the 1798 Alien Enemies Act, he ordered expedited deportations, including those targeting unaccompanied minors. U.S. Immigration and Customs Enforcement (ICE) has carried out mass raids, even in sanctuary cities, schools, and hospitals. This institutional offensive has intensified the criminalization of undocumented individuals, while the use of military forces in urban areas has undermined legal certainty and created an atmosphere of insecurity that fractures social cohesion and amplifies collective fear. In the commercial sphere, President Donald Trump has promoted executive orders imposing tariffs on Mexican exports of steel, aluminum, and automobiles, justifying such measures with arguments related to the trade deficit, irregular migration flows, and efforts to combat fentanyl trafficking. Although his administration has temporarily suspended some duties on products covered by the USMCA, these unilateral decisions have heightened uncertainty in the bilateral relationship by contradicting commitments made under the agreement. Constant threats to expand tariffs to goods not included in the treaty, along with the use of extraordinary powers to impose trade restrictions, have eroded the climate of trust between the productive sectors of both countries. In response, the Mexican government has pursued diplomatic actions and dialogue mechanisms aimed at ensuring the proper implementation of the USMCA and establishing safeguards to reduce the risks posed by protectionist measures that affect the stability and predictability of regional trade. In the current context, President Trump has disregarded the strategic importance of the United States’ historic allies and trade partners by adopting measures that have eroded trust not only with Mexico but also with other key partners such as Canada and the European Union. This situation has confronted the Mexican government with a complex challenge: preserving the stability of its most important economic relationship while also maintaining a strong consular protection policy. To this end, Mexico operates one of the world’s largest consular networks, with 53 consulates distributed throughout U.S. territory. The work of the Mexican Foreign Service is essential in this scenario, as it strengthens diplomatic dialogue and underscores to Washington that Mexico shares democratic and economic values with the United States. Recognizing mutual interdependence is vital: the prosperity and stability of both countries are intertwined, and a strong bilateral relationship is a key component of sustained economic growth in North America as a whole. Although it is uncertain what future decisions President Trump may make, the Mexican government must prioritize dialogue and political coordination as underlying strategies of its foreign policy, avoiding any confrontational maneuvers, as these only undermine the bilateral relationship. President Claudia Sheinbaum’s administration faces the critical task of accurately identifying the priorities of the U.S. government to act proactively with clarity and consistency. Mexico cannot allow its foreign policy to be reduced to merely reacting to unilateral initiatives marked by aggressive rhetoric and uncertainty. In this context, the Mexican Foreign Service must firmly exercise its well-established negotiating capacity to consolidate Mexico’s position as a reliable neighbor and a key actor in the regional economic structure. The bilateral relationship must clearly convey that the prosperity of the United States is closely linked to Mexico’s stability and growth — an interest grounded in a shared logic of structural interdependence.

Abstract The so-called Anglophone Caribbean has historically been an area of strategic importance for Cuban foreign policy. With more than half a century of history, Cuba-CARICOM ties constitute a successful example due to their comprehensiveness, strength, dynamism, and concrete results in terms of political coordination and cooperation. However, in a complex and changing international context, various elements constitute threats to the effective execution of Cuban foreign policy toward the subregion, mostly linked to structural difficulties facing Caribbean states and their integration into the international economy, as well as the effects of the blockade and the policy of economic suffocation implemented by the United States against Cuba, which has intensified with Trump's arrival as president. Likewise, there are opportunities that can be seized to preserve the privileged historical relationship that Cuba maintains with this subregional bloc. Introduction The Caribbean has historically been a region of strategic importance for Cuba's foreign policy, primarily because it constitutes its natural environment and setting, to which it belongs not only for geographical reasons but also due to historical and cultural ties. Cuba's connections with the so-called non-Hispanic Caribbean even predate the consolidation of the Cuban nation, considering the constant influence of intra-Caribbean migratory flows during the colonial era. This intensified with the massive arrival of laborers — mainly Haitians and Jamaicans — to the largest of the Antilles during the early decades of the 20th century, a migration flow that continued until the 1950s. Cuba shares with Caribbean nations a historical legacy linked to the tragic scourge of slavery, associated with the plantation economy. This involved, on one hand, the forced migration of a large African population, and on the other, a series of similar characteristics in terms of socio-economic structures — although the differences among the various European colonial powers present in the region should not be overlooked. After the triumph of the Cuban Revolution in 1959, Cuba's ties with the non-Hispanic Caribbean went through various phases, particularly since 1972, when four newly independent Caribbean nations (Barbados, Jamaica, Guyana, and Trinidad and Tobago) collectively decided to reestablish diplomatic relations with Cuba. This decision ignored the OAS agreements of July 1964, which had mandated the political, diplomatic, and economic severance of relations between the governments of the continent and the Island. It was during the 1990s and into the 21st century that the most solid foundations were laid for articulating a coherent, harmonious, and coordinated projection that acknowledges the real importance of the Caribbean subregion for the objectives of Cuban foreign policy. The results achieved thus far in terms of coordination, political dialogue, and cooperation have led several authors to describe Cuba's policy toward the Caribbean as one of the most dynamic and effective aspects of the Island’s foreign outreach in recent years. The aim of this paper is to provide an updated analysis of the Cuban government’s external projection toward the Caribbean, focusing on the threats and opportunities that, in the foreseeable future, may impact the country’s interactions with this subregion under the leadership of President Miguel Díaz-Canel Bermúdez. It is important to clarify that, from a methodological standpoint, this paper focuses primarily on the group of countries that make up the Caribbean Community (CARICOM), most of which are island nations, although three are located on the mainland (Belize, Guyana, and Suriname). As noted by scholar Milagros Martínez Reinosa in her work “Cuba’s Relations with the Caribbean,” this is a “group of nations with marked differences, determined by their respective geographic and population characteristics, by the colonial powers that divided up this part of the world, and by the unique socio-economic development of each. This group, in which the so-called English-speaking insular Caribbean predominates, includes (…) different economic systems and forms of political organization, with varying levels of development, economic potential, and geographic size” (Martínez, 2011, p. 203). Development Historical Analysis of Cuba’s Foreign Projection Toward the Caribbean It is well known that, in the historical period following the triumph of the Cuban Revolution, significant progress was made in the Caribbean’s decolonization processes. Gradually, and with particular characteristics in each case, several countries achieved independence: Jamaica (1962), Trinidad and Tobago (1962), Guyana (1966), Barbados (1966), The Bahamas (1973), Grenada (1974), and Suriname (1975). Later, others followed: Dominica (1978), Saint Vincent and the Grenadines (1979), Saint Lucia (1979), Belize (1981), Antigua and Barbuda (1981), and Saint Kitts and Nevis (1983). At the same time, the first steps were taken toward economic integration in the subregion, marked notably by the signing of the Treaty of Chaguaramas in 1973. This treaty established the Caribbean Community and set the goal of creating the Caribbean Common Market, both known by the acronym CARICOM. These agreements aimed to advance economic cooperation and integration, as well as to establish a degree of coordination in foreign policy among the governments of the member states. All of this laid the groundwork for building a subregional institutional framework, giving these small states greater negotiating power and the ability to act jointly, both within international organizations and within the Inter-American System itself. One of the most representative examples of the emerging political coordination among these countries was the previously mentioned establishment of diplomatic relations with Cuba by the governments of Barbados, Jamaica, Guyana, and Trinidad and Tobago in December 1972. This event marked the beginning of a new era in the foreign policy of the revolutionary Cuba, enabling cooperation and mutual support with the newly independent Caribbean states. However, in 1983, the U.S. invasion of Grenada — which was supported not only by the OAS but also by members of the Organization of Eastern Caribbean States (OECS), along with Barbados and Jamaica — somewhat deteriorated Cuba’s relations with the subregion. Beginning in the early 1990s, a new, more dynamic and productive period began in Cuba’s relations with the Caribbean. In 1993, the Cuba-CARICOM Joint Commission was established, and throughout the decade, Cuba gradually intensified its engagement with CARICOM member states — particularly following the creation, in 1994, of the Association of Caribbean States (ACS). This organization included all Caribbean island states, along with Central America, Mexico, Colombia, and Venezuela. The ACS provided a particularly favorable space for Cuba’s foreign policy outreach in the region, as it was outside the sphere of influence of the United States and offered conditions that allowed the Cuban government to assume a leadership role and promote a regional dynamic focused on cooperation. Cuba’s strategic projection toward the Caribbean reached a high point with the holding — at the initiative of the Cuban government — of the First CARICOM-Cuba Summit, held in Havana in December 2002, marking the 30th anniversary of the establishment of diplomatic relations with Barbados, Guyana, Jamaica, and Trinidad and Tobago. At this historic meeting, attended by all CARICOM heads of government, common goals and guidelines were set to shape relations between Cuba and the subregional bloc. During the summit, a Trade and Economic Cooperation Agreement was signed —previously negotiated two years earlier during the Joint Commission meeting in Santiago de Cuba. The agreement aimed to promote trade in goods and services, establish financial arrangements to facilitate commerce, encourage market access, foster the creation of joint ventures, protect investments, and promote information exchange. This agreement was later updated in 2006 to reflect new economic and commercial realities. From that point on, the Cuban Ministry of Foreign Affairs began implementing the so-called Comprehensive Caribbean Plan (PIC, in Spanish), which integrated all actions directed toward the region with the explicit goal of contributing to the fundamental objectives of Cuba’s foreign policy (Martínez, 2011, p. 217). In the years immediately following, ties were rapidly strengthened at the highest levels, both bilaterally and with CARICOM. Some have described as an “avalanche” the large number of official visits to Cuba by Caribbean heads of government between 2002 and 2005 (the year of the Second CARICOM-Cuba Summit), reflecting the success of Cuba’s political-diplomatic outreach in the region and the high priority the Caribbean had acquired in its foreign policy agenda. This period also saw a sustained increase in Cuban cooperation in areas such as health, education, sports, culture, and more. At the Third Summit, held in 2008, cooperation was reaffirmed as the central and leading element in Cuba’s intergovernmental relations with the Caribbean, with expanded and deepened assistance across a wide range of fields —many of them supported by the Bolivarian Government of Venezuela. At the same time, the emergence of political coordination and cooperation initiatives such as ALBA-TCP and Petrocaribe — and the subsequent inclusion of some CARICOM countries in the former — multiplied opportunities for interaction, political alignment, and regional coordination. Similarly, both sides have maintained close coordination in various international forums, including the UN General Assembly, UNCTAD, WIPO, UNIDO, FAO, WTO, the Non-Aligned Movement (NAM), the G-77+China, and the Alliance of Small Island States (AOSIS). This international collaboration has been strengthened by the clear political will and the ability of both parties to resolve differences constructively. CARICOM’s solidarity with Cuba has been particularly notable in its unanimous stance against the U.S. embargo. To date, eight CARICOM-Cuba Summits have been held, the most recent one taking place in Barbados, attended by Cuban President Miguel Díaz-Canel Bermúdez. On that occasion, he also made an official visit to Barbados and toured two other countries —Saint Vincent and the Grenadines and Grenada. According to recent figures, there are currently more than 850 Caribbean scholarship students in Cuba, with over 6,000 having graduated. Additionally, more than 2,000 Cuban professionals are currently providing services in CARICOM countries. Cuba’s Foreign Projection Toward the Caribbean in the Current Context: Threats and Opportunities For Cuba, maintaining strong relations with CARICOM remains a priority. From a political standpoint, it is strategically important to preserve a close and positive relationship with the countries that make up this subregional organization, as they often achieve high levels of consensus on key international issues. As a relatively large bloc in terms of membership, this often translates into an equal number of votes in international organizations. This is particularly relevant considering the transformations the international system has undergone in the 21st century — marked by the gradual decline of U.S. global leadership, the emergence of an increasingly multipolar world, the shift of economic and commercial dynamism toward the Asia-Pacific region, and the growing influence of new information technologies, among other factors. These changes pose significant challenges to the Cuban government’s foreign outreach and have also influenced the implementation of U.S. foreign policy in the region, on one hand, on curbing the progress of resistance movements to its model of regional domination, and on the other, on trying to counter the growing influence of extra-regional powers in the hemisphere. Currently, all independent Caribbean states maintain diplomatic missions in Havana, and Cuba does the same in each of those countries. This makes Cuba a key and prominent actor in the region and highlights the importance CARICOM member states place on their relationship with Cuba. Within the Caribbean Community there is a strong consensus on condemning the U.S. embargo and recognizing Cuba’s cooperation efforts — reflected in joint declarations across both global and regional multilateral organizations. However, economic relations between Cuba and CARICOM have significantly lagged the levels achieved in the political and cooperation spheres. Despite the existence of a Trade and Economic Cooperation Agreement that includes broad tariff preferences (ALADI, 2011), trade volumes remain very low and are highly concentrated in a few countries —such as Trinidad and Tobago ($57.9 million), Jamaica ($3.2 million), Guyana ($507,000), and Suriname ($84,000). Altogether, total trade amounts to approximately $61 million (National Office of Statistics and Information—ONEI, 2024, pp. 233–236). The underdevelopment of economic ties is not primarily due to a lack of willingness on either side to implement coordinated actions but rather stems from more complex causes related to the economic structures of Caribbean islands and how they are integrated into the global economy. It is also important to consider that both Cuba and most CARICOM members are classified as Small Island Developing States (SIDS), a condition that presents shared development challenges. Factors such as limited economic and geographic size, high levels of openness and dependence on the international economy, low diversification, transportation and connectivity issues, and high exposure to the effects of climate change and extreme weather events, among others, represent significant obstacles to the development of multifaceted ties between Cuba and the Caribbean — particularly in the area of economic and trade relations (Laguardia, 2022, p. 179). Threats The arrival of the Republican administration led by Donald Trump to the U.S. government undoubtedly represents a threat to Cuba’s relations with the Caribbean and, more broadly, to its foreign projection toward the region. The appointment of controversial figures closely linked to the anti-Cuban far-right in the U.S. — such as Marco Rubio and Mauricio Claver-Carone as Secretary of State and Head of Latin American and Caribbean Affairs at the State Department, respectively — forecasts an extremely difficult scenario for Cuba. This will greatly hinder the long-sought development of economic and trade ties with CARICOM, due to the tightening of the blockade, the potential implementation of additional unilateral measures, and Cuba’s reinstatement on the list of State Sponsors of Terrorism. It is undeniable that the blockade — significantly reinforced in recent years and expanded in its extraterritorial reach — currently stands as one of the major obstacles to elevating Cuba-CARICOM economic relations to the same level as their political ties. This remains a clear objective within Cuba’s foreign policy approach to the region. Broadly speaking, the blockade and the aggressive U.S. policy prevent Cuba from operating under normal conditions in the international market by limiting access to credit and financing, disrupting financial operations, reducing export revenues, and creating an intimidating environment for potential foreign investors. All these factors have worsened the Island’s economic crisis and intensified issues such as declining export capacity and foreign currency shortages, directly impacting Cuba’s trade with the rest of the world, including the Caribbean. These challenges are compounded by logistical limitations that hinder intra-Caribbean trade. Furthermore, the lack of mutual understanding of institutional and bureaucratic systems remains a significant barrier to expanding economic ties (Marín, Martínez, & Laguardia, 2024). Nonetheless, even under current complex conditions, there are still possibilities and spaces to develop broader and deeper economic relations, based on the principle of identifying areas of complementarity and leveraging mutual strengths and opportunities. In this regard, the internationally recognized scientific achievements of Cuba’s biotechnology and pharmaceutical sectors, along with a wide catalog of high-quality, advanced technology products, offer a valuable opportunity to increase exports to the region while also strengthening the healthcare systems of CARICOM countries. Additionally, other biotech products developed by Cuban companies and institutions —applicable in agriculture and livestock — could contribute to CARICOM’s efforts to achieve greater levels of food sovereignty. Likewise, the emerging private sector of small and medium-sized enterprises (SMEs) in Cuba has gained increasing importance in the national economy, particularly in foreign trade, and shows strong potential to help boost commercial exchange and business between Cuba and the Caribbean nations. On the other hand, another threat to Cuba’s foreign projection toward the region —particularly regarding the development of its economic relations — comes from the financial limitations caused by the inclusion of several Caribbean states on blacklists of tax havens, as well as their classification as middle-income countries. This classification prevents them from applying for development aid and other preferential financing. All of this adds to the challenges Cuba already faces because of the U.S. blockade. Another significant threat is the intensification of the effects of climate change, particularly the increasing occurrence of extreme weather events. These phenomena damage ecosystems and biodiversity, destroy agriculture, reduce tourism revenues, contribute to food insecurity, damage infrastructure, and create a constant need for budgetary spending and public debt, among other harmful impacts. Also, we also consider as a threat, — particularly over the past decade — the decline of Venezuela’s economic capacity to meet the energy demands of CARICOM countries and to support other cooperation projects in the Caribbean, especially under initiatives such as ALBA-TCP and Petrocaribe, in which Cuba played an important role. Additionally, there is the ongoing conflict over the Essequibo region, where there is strong consensus among CARICOM countries in support of Guyana’s position. This places Cuba in a complex position regarding how to approach the issue — an issue also used by the United States to exert pressure on Venezuela. Compounding this is the campaign promoted by the U.S. and its regional allies against the government of President Nicolás Maduro in the context of the Venezuelan elections and his inauguration, which has triggered a wide-ranging political, diplomatic, and propaganda offensive. While some Caribbean states have aligned with U.S. positions, it is worth noting that the majority have remained outside of this campaign. For CARICOM member states, the United States remains the primary “provider” of security. The need for cooperation and coordination in security matters with the U.S. is undeniable, especially given shared challenges such as cross-border criminal flows, the Caribbean’s status as the U.S. “third border,” economic dependency, and the need for aid and financing among CARICOM countries. This power asymmetry means that the U.S. uses security as a tool of pressure, which represents a constant threat to Cuba’s relations with the bloc — particularly under the new U.S. administration, which has prioritized migration and drug trafficking and embraces Monroe Doctrine-style views regarding inter-American relations. Another threat we identify is the weakening of regional mechanisms such as the ACS. Despite Cuba’s consistent efforts, the ACS has largely failed to meet its founding objectives since its establishment in 1994: to create a common economic space, preserve the Caribbean Sea, and promote the sustainable development of its member states – although there have been some positive experiences in cooperation on climate change mitigation and disaster risk prevention. Opportunities One key opportunity lies in the development of close coordination and the building of broad consensus on issues of shared interest and broader relevance on the multilateral agenda. This applies both within United Nations bodies and forums, as well as in platforms like the G77+China and the NAM. These spaces have demonstrated mutual support for various common demands and proposals, including: reparations for slavery; the principle of common but differentiated responsibilities regarding climate change; the reform of financing eligibility criteria; the Bridgetown Initiative as a proposal for reforming the global financial architecture; the lifting of the U.S. blockade on Cuba; recognition of Cuba’s international cooperation — particularly in the health sector; and the removal of Cuba from the U.S. list of State Sponsors of Terrorism, among others. Another ongoing opportunity for Cuba’s foreign policy projection lies in its respectful and diplomatic engagement, which has allowed Cuba to act as a political and diplomatic bridge between the Caribbean and the rest of Latin America. This role facilitates relationships that remain limited due to differing political and communicational frameworks, as well as stark economic asymmetries. This bridging role has been particularly evident in the Community of Latin American and Caribbean States (CELAC), where Cuba’s efforts supported the inclusion of a permanent CARICOM representative in the organization's leadership troika and ensured the incorporation of Caribbean concerns in CELAC’s joint declarations and statements. Another external opportunity is the growing interest of global powers and extra-regional actors in the Caribbean, most notably the People’s Republic of China. China has vast potential in economic and trade relations with the region, especially considering that CARICOM countries offer several attributes attractive to Chinese investors. China’s high demand for Caribbean products has driven its interest not only in production but also in developing transport infrastructure across the region to secure supply chains and reduce costs. In this context, the membership of Cuba and several Caribbean nations in the Belt and Road Initiative presents both an advantage and an opportunity. Cuba maintains a strong, strategic, high-level political and diplomatic relationship with China and can be considered as China’s principal ally in the region. This places Cuba in a unique position to play an important role in expanding China’s political engagement with CARICOM, particularly given that five CARICOM countries — Saint Lucia, Saint Kitts and Nevis, Saint Vincent and the Grenadines, Belize, and Haiti — still maintain diplomatic ties with Taiwan. In other words, Cuba could further leverage its privileged relationships with both parties to continue fostering political rapprochement, help expand economic and trade links with the subregion, and participate in various development projects with Chinese capital through a triangular cooperation. In this framework, Cuba can contribute with its expertise, knowledge, and highly qualified human capital in fields where many Caribbean nations lack capacity. At the same time, Cuba’s admission as an associate member of the BRICS represents an opportunity that opens promising prospects for cooperation, investment, and access to financing — within a framework that promotes a multipolar vision of the world, composed of several of the largest and most dynamic economies on the planet. In addition to its strategic geographic location as the “Key to the Gulf,” which facilitates access to major markets in Latin America and the Caribbean, Cuba can contribute to BRICS with an influential and privileged political relationship with Caribbean countries, built over 50 years. This could help foster a strategic partnership between BRICS and the Caribbean. Likewise, Cuba’s historical cooperation ties and its high-level political and diplomatic dialogue with the African bloc — as well as with other countries of the so-called Global South — also represent an opportunity, as they can help bridge the Caribbean with these extra-regional actors, enabling coordination on common positions in multilateral arenas and fostering economic ties. In the case of Africa, CARICOM has aimed in recent years to strengthen relations with the continent, starting with the first summit between both blocs held virtually in 2021. This goal is clearly reflected in the signing of a Partnership Agreement by 12 of the 15 CARICOM member states with the African Export-Import Bank (Afreximbank), which has approved over $1.5 billion in investments for the Caribbean (Afreximbank, 2024). Moreover, cooperation between Cuba and CARICOM still offers a wide range of untapped opportunities, aligned with the specific needs and advantages of each party. As previously mentioned, Cuba has a highly skilled human workforce that can benefit the region. In this regard, triangular cooperation becomes a key mechanism for accessing funding from governmental and multilateral sources. The growing interest in the Caribbean by various powers — both Western and non-Western — also represents an opportunity to attract resources for key areas such as climate change mitigation, energy transition, and digitalization, where Cuba can participate with its trained professionals and developed capabilities (Marín, Martínez, & Laguardia, 2024, p. 10). Conclusions Cuba–CARICOM relations, with more than half a century of history, stand as a successful example of strategic comprehensiveness, coherence, and tangible achievements in political and cooperation matters. However, they still face the challenge of producing similar results in the economic and trade sphere, where progress has been limited. The main obstacles to achieving this goal are linked to the structural conditions and constraints of Caribbean economies and their integration into the global economy, as well as to the effects of the U.S. blockade and the economic strangulation policies implemented against Cuba. The worsening of Cuba’s economic crisis — driven by the tightening of the blockade, the imposition of new sanctions, and its continued inclusion on the State Sponsors of Terrorism list under a likely more aggressive policy by the new U.S. administration — poses a threat to the achievement of Cuba’s goals in the Caribbean. At the same time, the positive outlook generated by Cuba’s admission as an associate member of the BRICS presents an opportunity to develop a possible strategic alliance between the bloc and the Caribbean — supported by the privileged, trusting, and cooperative relationship that Cuba has built with Caribbean countries over more than 50 years. Cooperation has been the cornerstone of Cuba’s relations with the Caribbean, and despite challenges, it has remained intentional and prioritized. However, more efforts should be made to leverage other areas in which Cuba possesses expertise and highly qualified human capital. The potential of triangular cooperation, along with the growing interest of key international actors in the Caribbean, could represent a valuable opportunity for Cuba to maintain and expand its cooperation efforts in the region. References Cabrera Agudo, M.

In Latin America, Cuba, Nicaragua, and Venezuela are not alone in their support for Russia and its invasion of Ukraine. In many cases, support has been disguised as an interest in peace or a neutral stance towards the conflict, as seen in the cases of Colombia, Mexico, and Brazil. While we find manifold diplomatic approaches toward Russia and Ukraine in Latin America, the underlying motivations can be understood in terms of support or rejection. While a majority of nations reject the invasion, considering it a threat to territorial sovereignty and self-determination, others have been reluctant to place any blame on Russia. More broadly, there has been less of an ideological bloc and more of an anti-imperialist or anti-colonial sentiment, with a few exceptions, such as Gabrie Boric from Chile who has publicly repudiated Russia’s aggression against Ukraine. His opposition is a departure from other Latin American leftist leaders like Luiz Inácio Lula da Silva and Gustavo Francisco Petro who have been more critical of Volodymyr Zelensky than Vladimir Putin. However, we can still identify three distinctive approaches to the crisis: 1) geopolitical, 2) economic, and 3) historical. The region has a keen interest in keeping its doors open to Russia. BRICS members like Brazil have managed to maintain their alleged neutrality in the pursuit of peace—even as President Lula has explicitly supported  Putin—while simultaneously protecting their economic interests. Others like Colombia and Mexico have shielded their unwillingness to condemn Putin’s invasion of Ukraine in an apparent push for peace. On the economic front, attitudes towards Russia are more tenuous given that Russia’s capability for foreign direct investment has been significantly reduced by the brunt of the war, along with the impact of the economic sanctions that followed their aggression. To be sure, Russia’s investments in the region have been winding down for some time, with a decreasing profile in areas such as energy, oil, and gas, as well as software and IT. However, the economic ties are more significant in the cases of Cuba, Nicaragua, and Venezuela—where they are joined more by their subjection to economic sanctions, and therefore the necessity to evade the consequences of economic isolation. There are specific areas key to this alliance: Russian fertilisers, along with oil and diesel, are critical to bypassing Western sanctions. Meanwhile, historical ties are more consequential than is commonly understood. Misinterpretations of Russia’s Soviet past by leftist-governed Latin American countries and longstanding social and cultural commonalities partially explain the continued support from diverse leaders such as Lula and Jair Bolsonaro in Brazil. These ties, rooted in shared anti-colonial sentiments and cultivated over decades, and regardless of ideological shifts, illustrate Russia’s multifaceted regional influence. This context underscores the fact that Russia’s regional impact transcends ideological lines, with both left and right-wing governments either explicitly supporting Russia or criticising Ukraine’s NATO aspirations to justify Russia’s aggression. The return of Donald Trump to the White House has prominent leaders of the Latin American left aligning with the new administration, resulting in significant consequences for the region. The new US administration’s criticism of Kyiv resonates with positions held by Brazil, Mexico, Colombia, Cuba, and Nicaragua. Despite ideological differences, their alignment emerges from a mix of political affinities, geopolitical strategies, and historical connections. Putin’s explicit defiance of Donald Trump’s negotiation efforts raises questions about Latin America’s influence over the conflict, largely due to its initial reluctance to adopt a decisive stance against Putin. The lonely voice condemning Putin’s war of attrition continues to be Chilean President Gabriel Boric, in stark contrast to Lula DaSilva and Gustavo Petro, who remain in Putin’s corner, making it unlikely they can be viewed as honest brokers in a peace initiative. Trump’s policies have prompted Brazil and Colombia to voice limited concerns about US plans for Ukraine, although still refraining from outright condemnation of Russia. This stance appears less a genuine support for Ukraine and more an opposition to US involvement in peace processes, even blaming Ukraine as partially responsible. Meanwhile, ideology alone has proven insufficient to prompt unified condemnation of Russia or widespread support for Ukraine in Latin America. Previous efforts by the Biden administration to secure regional military assistance for Ukraine were met with firm rejection and reluctance. This distancing, interpreted as tacit support for Russia, contributes to concerns about increasing authoritarian tendencies in the region, reflecting a diminished commitment to emerging democracies in crisis. Effectively abandoned by the international community, Ukraine faces negotiations with nations seeking its valuable earth minerals in exchange for protection, essentially framing it within a debt relief context. The absence of significant Latin American critique of this neocolonial approach underscores a troubling shift where sovereignty and self-determination appear increasingly disposable, contingent upon geopolitical interests and contexts. Maria I.

Abstract We examine the roles of Gold and Bitcoin as a hedge, a safe haven, and a diversifier against the coronavirus disease 2019 (COVID-19) pandemic and the Ukraine War. Using a rolling window estimation of the dynamic conditional correlation (DCC)-based regression, we present a novel approach to examine the time-varying safe haven, hedge, and diversifier properties of Gold and Bitcoin for equities portfolios. This article uses daily returns of Gold, Bitcoin, S&P500, CAC 40, and NSE 50 from January 3, 2018, to October 15, 2022. Our results show that Gold is a better safe haven than the two, while Bitcoin exhibits weak properties as safe haven. Bitcoin can, however, be used as a diversifier and hedge. This study offers policy suggestions to investors to diversify their holdings during uncertain times. Introduction Financial markets and the diversity of financial products have risen in both volume and value, creating financial risk and establishing the demand for a safe haven for investors. The global financial markets have faced several blows in recent years. From the Global Financial Crisis (GFC) to the outbreak of the pandemic and uncertainty regarding economic policy measures of governments and central banks, the financial markets including equity markets around the world were faced with severe meltdowns. This similar behavior was observed in other markets including equity and commodity markets, resulting in overall uncertainty. In this scenario, the investors normally flock toward the safe-haven assets to protect their investment. In normal situations, investors seek to diversify or hedge their assets to protect their portfolios. However, the financial markets are negatively impacted when there are global uncertainties. Diversification and hedging methods fail to safeguard investors’ portfolios during instability because almost all sectors and assets are negatively affected (Hasan et al., 2021). As a result, investors typically look for safe-haven investments to safeguard their portfolios under extreme conditions (Ceylan, 2022). Baur and Lucey (2010) provide the following definitions of hedge, diversifier, and safe haven: Hedge: An asset that, on average, has no correlation or a negative correlation with another asset or portfolio. On average, a strict hedge has a (strictly) negative correlation with another asset or portfolio.Diversifier: An asset that, on average, has a positive correlation (but not perfect correlation) with another asset or portfolio. Safe haven: This is the asset that in times of market stress or volatility becomes uncorrelated or negatively associated with other assets or a portfolio. As was previously indicated, the significant market turbulence caused by a sharp decline in consumer spending, coupled with insufficient hedging opportunities, was a common feature of all markets during these times (Yousaf et al., 2022). Nakamoto (2008) suggested a remedy by introducing Bitcoin, a “digital currency,” as an alternative to traditional fiduciary currencies (Paule-Vianez et al., 2020). Bitcoin often described as “Digital Gold” has shown greater resilience during periods of crises and has highlighted the potential safe haven and hedging property against uncertainties (Mokni, 2021). According to Dyhrberg (2016), the GFC has eased the emergence of Bitcoin thereby strengthening its popularity. Bouri et al. (2017) in their study indicate that Bitcoin has been viewed as a shelter from global uncertainties caused by conventional banking and economic systems. Recent research has found that Bitcoin is a weak safe haven, particularly in periods of market uncertainty like the coronavirus disease 2019 (COVID-19) crisis (Conlon & McGee, 2020; Nagy & Benedek, 2021; Shahzad et al., 2019; Syuhada et al., 2022). In contrast to these findings, a study by Yan et al. (2022) indicates that it can function as a strong safe haven in favorable economic times and with low-risk aversion. Ustaoglu (2022) also supports the strong safe-haven characteristic of Bitcoin against most emerging stock market indices during the COVID-19 period. Umar et al. (2023) assert that Bitcoin and Gold are not reliable safe-havens. Singh et al. (2024) in their study reveal that Bitcoin is an effective hedge for investments in Nifty-50, Sensex, GBP–INR, and JPY–INR, at the same time a good diversifier for Gold. The study suggests that investors can incorporate Bitcoin in their portfolios as a good hedge against market volatility in equities and commodities markets. During the COVID-19 epidemic, Barbu et al. (2022) investigated if Ethereum and Bitcoin could serve as a short-term safe haven or diversifier against stock indices and bonds. The outcomes are consistent with the research conducted by Snene Manzli et al. (2024). Both act as hybrid roles for stock market returns, diversifiers for sustainable stock market indices, and safe havens for bond markets. Notably, Bhuiyan et al. (2023) found that Bitcoin provides relatively better diversification opportunities than Gold during times of crisis. To reduce risks, Bitcoin has demonstrated a strong potential to operate as a buffer against global uncertainty and may be a useful hedging tool in addition to Gold and similar assets (Baur & Lucey, 2010; Bouri et al., 2017; Capie et al., 2005; Dyhrberg, 2015). According to Huang et al. (2021), its independence from monetary policies and minimal association with conventional financial assets allow it to have a safe-haven quality. Bitcoins have a substantial speed advantage over other assets since they are traded at high and constant frequencies with no days when trading is closed (Selmi et al., 2018). Additionally, it has been demonstrated that the average monthly volatility of Bitcoin is higher than that of Gold or a group of international currencies expressed in US dollars; nevertheless, the lowest monthly volatility of Bitcoin is lower than the maximum monthly volatility of Gold and other foreign currencies (Dwyer, 2015). Leverage effects are also evident in Bitcoin returns, which show lower volatilities in high return periods and higher volatilities in low return times (Bouri et al., 2017; Liu et al., 2017). According to recent research, Bitcoins can be used to hedge S&P 500 stocks, which increases the likelihood that institutional and retail investors will build secure portfolios (Okorie, 2020). Bitcoin demonstrates strong hedging capabilities and can complement Gold in minimizing specific market risks (Baur & Lucey, 2010). Its high-frequency and continuous trading further enrich the range of available hedging tools (Dyhrberg, 2016). Moreover, Bitcoin spot and futures markets exhibit similarities to traditional financial markets. In the post-COVID-19 period, Zhang et al. (2021) found that Bitcoin futures outperform Gold futures.Gold, silver, palladium, and platinum were among the most common precious metals utilized as safe-haven investments. Gold is one such asset that is used extensively (Salisu et al., 2021). Their study tested the safe-haven property of Gold against the downside risk of portfolios during the pandemic. Empirical results have also shown that Gold functions as a safe haven for only 15 trading days, meaning that holding Gold for longer than this period would result in losses to investors. This explains why investors buy Gold on days of negative returns and sell it when market prospects turn positive and volatility decreases (Baur & Lucey, 2010). In their study, Kumar et al. (2023) tried to analyse the trends in volume throughout futures contracts and investigate the connection between open interest, volume, and price for bullion and base metal futures in India. Liu et al. (2016) in their study found that there is no negative association between Gold and the US stock market during times of extremely low or high volatility. Because of this, it is not a strong safe haven for the US stock market (Hood & Malik, 2013). Post-COVID-19, studies have provided mixed evidence on the safe-haven properties of Gold (Bouri et al., 2020; Cheema et al., 2022; Ji et al., 2020). According to Kumar and Padakandla (2022), Gold continuously demonstrates safe-haven qualities for all markets, except the NSE, both in the short and long term. During the COVID-19 episode, Gold’s effectiveness as a hedge and safe-haven instrument has been impacted (Akhtaruzzaman et al., 2021). Al-Nassar (2024) conducted a study on the hedge effectiveness of Gold and found that it is a strong hedge in the long run. Bhattacharjee et al. (2023) in their paper examined the symmetrical and asymmetrical linkage between Gold price levels and the Indian stock market returns by employing linear autoregressive distributed lag and nonlinear autoregressive distributed lag models. The results exhibit that the Indian stock market returns and Gold prices are cointegrated. According to the most recent study by Kaczmarek et al. (2022), Gold has no potential as a safe haven, despite some studies on the COVID-19 pandemic showing contradictory results. The co-movements of Bitcoin and the Chinese stock market have also normalized as a result of this epidemic (Belhassine & Karamti, 2021). Widjaja and Havidz (2023) verified that Gold was a safe haven asset during the COVID-19 pandemic, confirming the Gold’s safe-haven characteristic. As previously pointed out, investors value safe-haven investments in times of risk. Investors panic at these times when asset prices fall and move from less liquid (risky) securities to more liquid (safe) ones, such as cash, Gold, and government bonds. An asset must be bought and sold rapidly, at a known price, and for a reasonably modest cost to be considered truly safe (Smales, 2019). Therefore, we need to properly re-examine the safe-haven qualities of Gold and Bitcoin due to the mixed evidences regarding their safe-haven qualities and the impact of COVID-19 and the war in Ukraine on financial markets. This work contributes to and deviates from the body of existing literature in the following ways. We propose a novel approach in this work to evaluate an asset’s time-varying safe haven, hedge, and diversifier characteristics. This research examines the safe haven, hedging, and diversifying qualities of Gold and Bitcoin against the equity indices; S&P 500, CAC 40, and NSE 50. Through the use of rolling window estimation, we extend the methodology of Ratner and Chiu (2013) by estimating the aforementioned properties of the assets. Comparing rolling window estimation to other conventional techniques, the former will provide a more accurate representation of an asset’s time-varying feature. This study explores the conventional asset Gold’s time-varying safe haven, hedging, and diversifying qualities during crises like the COVID-19 pandemic and the conflict in Ukraine. We use Bitcoin, an unconventional safe-haven asset, for comparison. Data and Methodology We use the daily returns of three major equity indices; S&P500, CAC 40, and NSE 50 from January 3, 2018, to October 15, 2022. The equity indices were selected to represent three large and diverse markets namely the United States, France, and India in terms of geography and economic development. We assess safe-haven assets using the daily returns of Gold and Bitcoin over the same time. Equity data was collected from Yahoo Finance, Bitcoin data from coinmarketcap.com, and Gold data from the World Gold Council website. Engle (2002) developed the DCC (Dynamic Conditional Correlation)-GARCH model, which is frequently used to assess contagion amid pandemic uncertainty or crises. Time-varying variations in the conditional correlation of asset pairings can be captured using the DCC-GARCH model. Through employing this model, we can analyse the dynamic behavior of volatility spillovers. Engle’s (2002) DCC-GARCH model contains two phases; 1. Univariate GARCH model estimation2. Estimation of time-varying conditional correlation. For its explanation, mathematical characteristics, and theoretical development, see here [insert the next link in “the word here” https://journals.sagepub.com/doi/10.1177/09711023251322578] Results and Discussion The outcomes of the parameters under the DCC-GARCH model for each of the asset pairs selected for the investigation are shown in Table 1.   First, we look at the dynamical conditional correlation coefficient, ρ.The rho value is negative and insignificant for NSE 50/Gold, NSE 50 /BTC, S&P500/Gold, and S&P500/BTC indicating a negative and insignificant correlation between these asset pairs, showing Gold and Bitcoin as potential hedges and safe havens. The fact that ρ is negative and significant for CAC 40/Gold suggests that Gold can be a safe haven against CAC 40 swings. The asset pair CAC/BTC, on the other hand, has possible diversifier behavior with ρ being positive but statistically insignificant. Next, we examine the behavior of the DCC-GARCH parameters; α and β. We find that αDCC is statistically insignificant for all the asset pairs, while βDCC is statistically significant for all asset pairs. βDCC quantifies the persistence feature of the correlation and the extent of the impact of volatility spillover in a particular market’s volatility dynamics. A higher βDCC value implies that a major part of the volatility dynamics can be explained by the respective market’s own past volatility. For instance, the NSE 50/Gold’s βDCC value of 0.971 shows that there is a high degree of volatility spillover between these two assets, with about 97% of market volatility being explained by the assets’ own historical values and the remainder coming from spillover. Thus, we see that the volatility spillover is highly persistent (~0.8) for all the asset pairs except NSE 50/BTC. The results above show that the nature of the dynamic correlation between the stock markets, Bitcoin and Gold is largely negative, pointing toward the possibility of Gold and Bitcoin being hedge/safe haven. However, a detailed analysis is needed to confirm the same by employing rolling window analysis, and we present the results in the forthcoming section. We present the rolling window results for S&P500 first. We present the regression results for Gold in Figure 1 and Bitcoin in Figure 2   Figure 1. Rolling Window Regression Results for S&P500 and Gold.Note: Areas shaded under factor 1 represent significant regression coefficients. In Figure 1, we examine the behavior of β0 (intercept term), β1, β2, and β3 (partial correlation coefficients). The intercept term β0 will give an idea about whether the asset is behaving as a diversifier or hedge. Here, the intercept term shows significance most of the time. However, during 2018, the intercept was negative and significant, showing that it could serve as a hedge during geopolitical tensions and volatilities in the global stock market. However, during the early stages of COVID-19, we show that the intercept is negative and showing statistical significance, suggesting that Gold could serve as a hedge during the initial shocks of the pandemic. These findings are contrary to the results in the study by Tarchella et al. (2024) where they found hold as a good diversifier. Later, we find the intercept to be positive and significant, indicating that Gold could act as a potential diversifier. But during the Russia-Ukraine War, Gold exhibited hedge ability again. Looking into the behavior of β1, which is the partial correlation coefficient for the tenth percentile of return distribution shows negative and insignificant during 2018. Later, it was again negative and significant during the initial phases of COVID-19, and then negative in the aftermath, indicating that Gold could act as a weak safe haven during the COVID-19 pandemic. Gold could serve as a strong safe haven for the SP500 against volatility in the markets brought on by the war in Ukraine, as we see the coefficient to be negative and large during this time. From β2 and β3, the partial correlation coefficients of the fifth and first percentile, respectively, show that Gold possesses weak safe haven properties during COVID-19 and strong safe haven behavior during the Ukraine crisis. Next, we examine the characteristics of Bitcoin as a hedge/diversifier/safe haven against the S&P500 returns. We present the results in Figure 2.   Figure 2. Rolling Window Regression Results for S&P500 and Bitcoin.Note: Areas shaded under factor 1 represent significant regression coefficients. Like in the previous case, we begin by analysing the behavior of the intercept coefficient, which is β0. As mentioned earlier the intercept term will give a clear picture of the asset’s hedging and diversifier property. In the period 2018–2019, the intercept term is positive but insignificant. This could be due to the large volatility in Bitcoin price movements during the period. It continues to be minimal (but positive) and insignificant during 2019–2020, indicating toward weak diversification possibility. Post-COVID-19 period, the coefficient shows the significance and positive value, displaying the diversification potential. We see that the coefficient remains positive throughout the analysis, confirming Bitcoin’s potential as a diversifier. Looking into the behavior of β1 (the partial correlation coefficient at tenth percentile), it is positive but insignificant during 2018. The coefficient is having negative sign and showing statistical significance in 2019, suggesting that Bitcoin could be a good safe haven in that year. This year was characterized by a long list of corporate scandals, uncertainties around Brexit, and tensions in global trade. We can observe that throughout the COVID-19 period, the coefficient is showing negative sign and negligible during the March 2020 market meltdown, suggesting inadequate safe-haven qualities. However, Bitcoin will regain its safe-haven property in the coming periods, as the coefficient is negative and significant in the coming months. The coefficient is negative and shows statistical significance during the Ukrainian crisis, suggesting strong safe-haven property. Only during the Ukrainian crisis could Bitcoin serve as a safe haven, according to the behavior of β2, which displays the partial correlation coefficient at the fifth percentile. Bitcoin was a weak safe haven during COVID-19 and the Ukrainian crisis, according to β3, the partial correlation coefficient for the first percentile (coefficient negative and insignificant). According to the overall findings, Gold is a stronger safe haven against the S&P 500’s swings. This result is consistent with the previous studies of Triki and Maatoug (2021), Shakil et al. (2018), Będowska-Sójka and Kliber (2021), Drake (2022), and Ghazali et al. (2020), etc. The same analysis was conducted for the CAC 40 and the NSE 50; the full analysis can be found here [insert the next link in “the word here” https://journals.sagepub.com/doi/10.1177/09711023251322578]. However, it is important to highlight the respective results: In general, we may say that Gold has weak safe-haven properties considering CAC40. We can conclude that Bitcoin’s safe-haven qualities for CAC40 are weak. We can say that Gold showed weak safe-haven characteristics during the Ukraine crisis and good safe-haven characteristics for the NSE50 during COVID-19. We may say that Bitcoin exhibits weak safe haven, but strong hedging abilities to NSE50. Concluding Remarks In this study, we suggested a new method to evaluate an asset’s time-varying hedge, diversifier, and safe-haven characteristics. We propose a rolling window estimation of the DCC-based regression of Ratner and Chiu (2013). Based on this, we estimate the conventional asset’s time-varying safe haven, hedging, and diversifying properties during crises like the COVID-19 pandemic and the conflict in Ukraine. For comparison purposes, we include Bitcoin, a nonconventional safe-haven asset. We evaluate Gold and Bitcoin’s safe haven, hedging, and diversifier properties to the S&P 500, CAC 40, and NSE 50 variations. We use a rolling window of length 60 to estimate the regression. From the results, we find that Gold can be considered as a better safe haven against the fluctuations of the S&P 500. In the case of CAC 40, Gold and Bitcoin have weak safe-haven properties. While Bitcoin demonstrated strong safe-haven characteristics during the Ukraine crisis, Gold exhibited strong safe-haven characteristics during COVID-19 for the NSE 50. Overall, the findings indicate that Gold is the better safe haven. This outcome is consistent with earlier research (Będowska-Sójka & Kliber, 2021; Drake, 2022; Ghazali et al., 2020; Shakil et al., 2018; Triki & Maatoug, 2021). When it comes to Bitcoin, its safe-haven feature is weak. Bitcoin, however, works well as a diversifier and hedge. Therefore, from a policy perspective, investing in safe-haven instruments is crucial to lower the risks associated with asset ownership. Policymakers aiming to enhance the stability of financial portfolios might encourage institutional investors and other market players to incorporate Gold into their asset allocations. Gold’s strong safe-haven qualities, proven across various market conditions, make it a reliable choice. Gold’s performance during crises like COVID-19 highlights its potential to mitigate systemic risks effectively. Further, Bitcoin could also play a complementary role as a hedge and diversifier, especially during periods of significant volatility such as the Ukraine crisis. While Bitcoin’s safe-haven characteristics are relatively weaker, its inclusion in a diversified portfolio offers notable value and hence it should not be overlooked. Further, policymakers may consider how crucial it is to monitor dynamic correlations and periodically rebalance portfolios to account for shifts in the safe haven and hedging characteristics of certain assets. Such measures could help reduce the risks of over-reliance on a single asset type and create more resilient portfolios that can better withstand global economic shocks. For future research, studies can be conducted on the estimation of the rolling window with different widths. This is important to understand how the safe-haven property changes across different holding periods. Further, more equity markets would be included to account for the differences in market capitalization and index constituents. This study can be extended by testing these properties for multi-asset portfolios as well. We intend to take up this study in these directions in the future. Data Availability StatementNot applicable.Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.FundingThe authors received no financial support for the research, authorship, and/or publication of this article.ReferencesAkhtaruzzaman M., Boubaker S., Lucey B.

Nuclear power capacity is expected to double, escalating from 413 gigawatts (GW) in early 2022 to 812 GW by 2050 within the net zero emissions (NZE) paradigm. The global energy landscape is undergoing significant transformation as nations strive to transition to more sustainable energy systems. Amidst this shift, nuclear power has emerged as a crucial component in the pursuit of a sustainable energy transition. This study examines nuclear power's multifaceted role in shaping sustainable energy transition. It delves into nuclear energy's contributions toward decarbonization efforts, highlighting its capacity to provide low-carbon electricity and its potential role in mitigating climate change. Furthermore, the study explores the challenges and opportunities associated with integrating nuclear power into energy transition strategies, addressing issues such as safety, waste management, and public perception. In conclusion, the global nuclear power capacity is anticipated to reach approximately 530 GW by 2050, representing a substantial shortfall of 35% compared with the trajectory outlined in the NZE pathway. Under the NZE scenario, nuclear power demonstrates exceptional expansion, nearly doubling from 413 GW in early 2022 to 812 GW by 2050. Concurrently, the trajectory highlights a transformative shift in renewable energy investments, with annual expenditures surging from an average of US$325 billion during 2016–2020 to an impressive US$1.3 trillion between 2031 and 2035. These projections underscore the critical role of nuclear and renewable energy investments in achieving global sustainability and emission reduction goals. Introduction Global warming and greenhouse gas emissions pose some of the most pressing challenges of the 21st century. The combustion of fossil fuels for electricity generation is a major contributor to these issues, releasing billions of tons of carbon dioxide (CO2) into the atmosphere annually (Abbasi et al., 2020; Nassar et al., 2024; Rekik and El Alimi, 2024a). In this context, nuclear energy emerges as a critical component of the solution. Unlike fossil fuels, nuclear power generates electricity with minimal greenhouse gas emissions, offering a reliable and scalable alternative to bridge the gap between energy demand and decarbonization goals. It operates independently of weather conditions, providing consistent energy output and complementing the intermittency of renewable sources like wind and solar (Rekik and El Alimi, 2024b, 2024c). Furthermore, advancements in nuclear technologies, including small modular reactors (SMRs) and generation IV reactors, have addressed historical concerns related to safety, waste management, and cost-effectiveness (Lau and Tsai, 2023). In 2022, global investment in low-emission fuels will maintain a robust growth trajectory, reaching a sum of US$13 billion. A significant portion of this investment was allocated toward liquid biofuels, totaling US$9.4 billion, and biogas, amounting to US$2.7 billion. It is important to emphasize that liquid biofuels constituted approximately 80% of the overall investment surge observed in 2022, with investments in biogas contributing 4% of the total. The residual portion of the investment was directed toward low-emission hydrogen production, which attained a sum of US$1.2 billion in 2022, representing an almost fourfold increase compared to the figures recorded in 2021 (Khaleel et al., 2024).Nuclear power is a pivotal component of low-carbon energy, which significantly contributes to the realization of a low-carbon economy and establishment of a green energy grid (Arvanitidis et al., 2023; El Hafdaoui et al., 2024; Fragkos et al., 2021). According to current data, 442 nuclear power reactors are operational worldwide, collectively generating 393 gigawatts (GW) of electricity, thereby furnishing a consistent and dependable source of low-carbon power (Mathew, 2022). Nuclear electricity constitutes approximately 11% of the total global electricity generation, representing a substantial portion of the global low-carbon electricity production (Alam et al., 2019). Recent advancements have enhanced the affordability and appeal of nuclear power as an alternative source of energy. These advancements encompass progress in large reactor technologies, the emergence of novel approaches such as advanced fuel utilization and SMRs, engineering breakthroughs facilitating the extension of operational lifespans for existing reactors, and innovations in materials science and improved waste management practices (Kröger et al., 2020; Zhan et al., 2021). Fast breeder reactor technology has transitioned into a commercial realm, offering benefits beyond electricity generation by enabling the production of surplus fuel and enhancing the efficiency of nuclear waste incineration, surpassing the capabilities of existing commercial reactor technologies (Lau and Tsai, 2023). Nuclear power plays a substantial role within a secure global trajectory toward achieving net zero emissions (NZE) (Addo et al., 2023; Dafnomilis et al., 2023). Nuclear power capacity experiences a twofold increase, progressing from 413 GW at the outset of 2022 to 812 GW by 2050 within the NZE paradigm. It is apparent that the annual additions to nuclear capacity peaked at 27 GW per year during the 2030s, surpassing the levels observed in the preceding decade. Despite these advancements, the global proportion of nuclear power within the overall electricity generation portfolio has experienced a marginal decline, settling at 8% (Murphy et al., 2023; Ruhnau et al., 2023). Emerging and developing economies (EMDEs) substantially dominate global growth, constituting over 90% of the aggregate, with China poised to ascend as a preeminent nuclear power producer prior to 2030. Concurrently, advanced economies collectively witness a 10% augmentation in nuclear power capacity as retirements are counterbalanced by the commissioning of new facilities, predominantly observed in nations such as the United States, France, the United Kingdom, and Canada (Bórawski et al., 2024). Furthermore, annual global investment in nuclear power has experienced a notable escalation, soaring from US$30 billion throughout the 2010s to surpass US$100 billion by 2030, maintaining a robust trajectory above US$80 billion by 2050 (IEA, 2022). In 2022, global nuclear power capacity experienced a modest increase of approximately 1.5 GW, reflecting a marginal year-on-year growth of 0.3%. This expansion was primarily driven by new capacity additions that surpassed the retirement of an over 6 GW of existing capacity (Fernández-Arias et al., 2023; Mendelevitch et al., 2018). EMDEs accounted for approximately 60% of the new capacity additions, underscoring their increasing significance in the global nuclear energy landscape. Conversely, more than half of the retirements were observed in advanced economies, including Belgium, the United Kingdom, and the United States. Table 1 shows the nuclear power capacity by region in the NZE from 2018 to 2030.   In alignment with the Net Zero Scenario, it is imperative for the global nuclear capacity to undergo an expansion averaging approximately 15 GW per annum, constituting a growth rate slightly exceeding 3% annually, until 2030. This strategic augmentation is crucial for sustaining the contribution of the nuclear sector to electricity generation, maintaining its share at approximately 10% (Liu et al., 2023). Such an expansion necessitates concerted efforts in both advanced economies and EMDEs. Furthermore, prioritizing the extension of operational lifetimes of existing nuclear facilities within G7 member states would not only fortify the existing low-emission infrastructure, but also facilitate the integration of new nuclear capacity, thereby augmenting the overall nuclear energy portfolio. [...] The significant contribution of nuclear power to sustainable energy transitions is underscored by its multifaceted role in addressing the pressing challenges of climate change and energy security (Asif et al., 2024). As nations worldwide endeavor to shift toward greener energy systems, nuclear power has emerged as a critical pillar of the decarbonization journey. Its ability to provide low-carbon electricity, mitigate climate change impacts by 2050, and enhance energy security highlights its pivotal importance in the broader context of sustainable energy transitions (Bhattacharyya et al., 2023; NEA, 2015). Thus, to fully realize its potential, challenges such as safety, waste management, and public perception must be addressed effectively. By leveraging robust policy frameworks, technological advancements, and international collaboration, nuclear power is poised to play a vital role in shaping the future of sustainable energy transitions on a global scale. Furthermore, the dynamic landscape of nuclear power development is evident in the significant influence exerted by EMDEs, particularly China, which is expected to emerge as a leading nuclear power producer by 2030 (Fälth et al., 2021; Nkosi and Dikgang, 2021). Concurrently, advanced economies are witnessing notable expansions in nuclear power capacity driven by the commissioning of new facilities to offset retirements (Budnitz et al., 2018). This trend is further reinforced by a notable surge in annual global investment in nuclear power, underscoring the sustained commitment to nuclear energy's pivotal role in sustainable energy transitions in the foreseeable future (IEA, 2019). The primary objective of this article is to explore the strategic role of nuclear power in advancing global sustainability goals and achieving zero emissions. The objective is structured around the following key agendas: •Nuclear power: prominence and green electricity source•Nuclear's role in achieving net zero by 2050•Nuclear power's significance in power system adequacySpecific technologies for sustainability in nuclear energy production•Investment in nuclear power•Addressing policy implications This comprehensive analysis aims to provide actionable insights into harnessing nuclear power for sustainable electricity generation and its pivotal role in achieving global zero-emission targets. Data and methodology This article conducts an in-depth analysis of the role of nuclear power in achieving sustainable electricity generation and supporting NZE targets. The article also addresses the potential of nuclear energy as a prominent and environmentally favorable electricity source, examining nuclear power's contribution toward the net zero by 2050 goal, its critical importance in ensuring power system adequacy, investment imperatives, and the broader policy implications.  [...] Nuclear power: prominence and green electricity source In 2020, nuclear power will constitute approximately 10% of the global electricity generation portfolio. This proportion, which had previously stood at 18% during the late 1990s, has experienced a decline; nonetheless, nuclear energy retains its status as the second-largest provider of low-emission electricity, trailing only hydroelectricity, and serves as the primary source within advanced economies. Despite the substantial proliferation of wind and solar PV technologies, nuclear electricity production in 2020 surpassed the aggregate output of these renewable sources. As of 2021, the global cumulative installed nuclear capacity has reached 413 GW, with 270 GW of this total being installed in advanced economies (Guidi et al., 2023; Halkos and Zisiadou, 2023; Pan et al., 2023; Zhang et al., 2022). Nuclear power generation during this period amounted to 2653 TWh, positioning it as the second largest source of electricity generation after hydropower, which generated 4275 TWh, as depicted in Figure 1.   In addition to its significant role in power generation, nuclear energy plays a crucial role in mitigating carbon dioxide (CO2) emissions. Since the 1970s, nuclear power has helped avoid the global release of approximately 66 gigatons (Gt) of CO2 globally, as shown in Figure 2.   Without the contribution of nuclear power, cumulative emissions from electricity generation would have increased by approximately 20%, whereas total energy-related emissions would have increased by 6% over this period (Wagner, 2021). Advanced economies accounted for more than 85% of these avoided emissions, with the European Union accounting for 20 Gt and the United States for 24 Gt, representing over 40% and 25% of total electricity generation emissions, respectively. In the absence of nuclear power, Japan would have experienced an estimated 25% increase in emissions from electricity generation, whereas Korea and Canada would have seen an increase of approximately 50%. Nuclear's role in achieving net zero by 2050 Nuclear energy has emerged as a pivotal low-emission technology within the trajectory toward achieving NZE (Pioro et al., 2019). In addition, it serves as a complementary force, bolstering the accelerated expansion of renewables, thereby facilitating the reduction of emissions from the global electricity sector to net zero by 2040 (Krūmiņš and Kļaviņš, 2023; Islam et al., 2024). Beyond its intrinsic contribution to fostering a low-emission electricity supply, nuclear power is significant as a dispatchable generating asset, fortifying supply security through its provision of system adequacy and flexibility. Furthermore, it is instrumental in furnishing heat for district heating networks and in selecting industrial facilities. Despite this, the prospective role of nuclear energy hinges significantly on the deliberations and determinations of policymakers and industry stakeholders concerning the pace of new reactor construction initiatives and the continued operational lifespan of existing nuclear facilities (Li et al., 2016; Li et al., 2015).In terms of the NZE trajectory, the global nuclear power capacity exhibits a remarkable surge, nearly doubling from 413 GW at the onset of 2022 to 812 GW by 2050 (Price et al., 2023; Utami et al., 2022). This augmentation primarily stems from the vigorous initiation of new construction endeavors, which effectively counterbalance the gradual decommissioning of numerous extant plants. Such an escalation constitutes a pronounced acceleration in comparison to the preceding three decades, characterized by a mere 15% increment in capacity, equivalent to approximately 60 GW (Haneklaus et al., 2023; Obekpa and Alola, 2023; Sadiq et al., 2023). Figure 3 demonstrates the nuclear power capacity within each country/region under the NZE by 2050 scenario.   The expected growth in nuclear power capacity far exceeds the path outlined by the current policies and legal frameworks. According to the Stated Policies Scenario (STEPS), the nuclear capacity is projected to reach approximately 530 GW by 2050, which is 35% lower than that of the NZE pathway (Espín et al., 2023; Nicolau et al., 2023; Nnabuife et al., 2023; Wang et al., 2023). Without a significant shift from recent nuclear power development trends, achieving NZE would require a limited reliance on a smaller range of low-emission technologies. This could compromise energy security and lead to higher total investment costs, resulting in increased electricity prices for consumers. Table 2 shows the average annual capacity addition for global nuclear power in NZE from 1981 to 2030.   In 2022, the global deployment of new nuclear power capacity witnessed a notable upsurge, with 7.9 GW added, representing a substantial 40% increase compared to the preceding year (Ho et al., 2019). It is worth bearing in mind that China spearheaded this expansion by completing the construction of two reactors, maintaining its streak for consecutive years as the leading contributor to global nuclear power capacity augmentation. It is noteworthy that the projects were successfully completed in various other nations, including Finland, Korea, Pakistan, and the United Arab Emirates. Additionally, significant strides were made in the initiation of new construction endeavors, with the commencement of construction activities on five reactors in China, two reactors in Egypt, and one reactor in Turkey (Hickey et al., 2021). Nuclear power's significance in power system adequacy Nuclear power facilities have persistently underpinned the dependability of power systems, thereby bolstering the adequacy of the system. Across diverse national contexts, nuclear power plants have historically maintained operational readiness, manifesting availability rates consistently exceeding 90%, thereby demonstrating their reliability in power generation. Given that a substantial proportion of nuclear power capacity directly contributes to system adequacy metrics, its significance in fortifying system reliability and adequacy significantly outweighs its proportional contribution to the total power capacity (Orikpete and Ewim, 2024; Frilingou et al., 2023; Raj, 2023; Ragosa et al., 2024). The contribution of nuclear power to system adequacy is demonstrated by the consistent trajectory of its share within the aggregate dispatchable power capacity, hovering at around 8% between 2021 and 2050 within the NZE framework (IEA, 2022; OIES, 2024). Dispatchable electricity sources have historically constituted the primary mechanism for ensuring system adequacy, a trend that endures within the NZE paradigm, especially as electricity systems undergo evolution marked by an escalating reliance on variable solar photovoltaic (PV) and wind energy sources (Marzouk, 2024; Moon et al., 2024; Wisnubroto et al., 2023). It is indisputable that unabated fossil fuel resources predominantly dominate dispatchable capacity; however, their prominence clearly diminishes, declining by a quarter by 2030 within the NZE framework and experiencing a precipitous decline thereafter. Unabated coal-fired power, currently the most substantial dispatchable source, anticipates a decline exceeding 40% in operational capacity by 2030 and approaches a state of negligible contribution by the early 2040s. Conversely, the unabated natural gas-fired power capacity exhibits a sustained level of stability until 2030, primarily driven by the necessity to offset the diminishing role of coal; nonetheless, it subsequently undergoes a rapid descent throughout the 2030s. Oil, constituting a comparatively minor contributor, experiences rapid phasing out across most regions, except for remote locales, within the delineated scenario (Makarov et al., 2023; Ren et al., 2024). Figure 4 highlights the global capacity of dispatchable power categorized by category in the scenario of achieving NZE by 2050.   In this context, fossil fuels equipped with Carbon Capture, Utilization, and Storage (CCUS) technology have emerged as notable contributors to bolstering system adequacy. Yet, nuclear power remains a steady contributor to the power system flexibility. In advanced economies, the proportion of hour-to-hour flexibility is projected to increase from approximately 2% to 5% by 2050. Similarly, in EMDEs, this ratio is anticipated to increase from 1% to 3% over the same temporal span (Jenkins et al., 2018). It is worth highlighting that in France, where nuclear power fulfills the lion's share of electricity generation requisites, flexibility has been ingrained within reactor designs (Ho et al., 2019). This feature enables certain plants to swiftly modulate their output to align with the fluctuating electricity supply and demand, operating in a load-following mode (Chen, 2024; Jin and Bae, 2023; Kanugrahan and Hakam, 2023). Although many nations have not habitually engaged nuclear power in such operational dynamics, a considerable number of reactors are capable of performing load-following operations with minimal or no requisite technical adaptations (Caciuffo et al., 2020). Figure 5 demonstrates the hour-to-hour power system flexibility based on the source and regional grouping in the NZE by the 2050 scenario.   Innovation holds promise in enhancing the flexibility of nuclear power. Advanced technological advancements, such as SMRs, can facilitate nuclear reactors to adjust their electricity output with greater ease, as illustrated in Figure 6 (Ho et al., 2019; Lee, 2024; Wisnubroto et al., 2023). Moreover, these technologies offer the prospect of enabling reactors to transition toward generating heat or producing hydrogen either independently or concurrently with electricity generation. Initiatives are underway to disseminate information to policymakers and planners regarding the potential cost advantages associated with enhancing nuclear power flexibility.  Figure 6 demonstrates the nuclear system augmented by wind turbines for trigeneration.   Investment in nuclear power The renaissance of nuclear power within the NZE trajectory necessitates a substantial surge in investment in the coming decades. This surge is envisaged to encompass the construction of new nuclear reactors and extension of operational lifespans for existing facilities. Within this scenario, annual global investment in nuclear power is poised to escalate to exceed US$100 billion during the initial half of the 2030s within the NZE framework, surpassing the threefold average investment level of US$30 billion recorded during the 2010s (IEA, 2022). Subsequently, investment levels are expected to gradually decline as the imperative for dispatchable low emissions generating capacity diminishes, tapering to approximately US$70 billion by the latter half of the 2040s (Kharitonov and Semenova, 2023; Zimmermann and Keles, 2023). Over the period spanning from 2021 to 2050, the allocation of investment toward nuclear power constitutes a fraction representing less than 10% of the aggregate investment dedicated to low-emission sources of electricity (IEA, 2022). By comparison, within this framework, the annual investment in renewable energy experiences a notable escalation, escalating from an average of US$325 billion during the interval from 2016 to 2020 to US$1.3 trillion during the period 2031–2035 (EEDP, 2023; Rekik and El Alimi, 2024d). It is worth noting that the latter consideration elucidates the rationale behind the disproportionate allocation of investment toward advanced economies in later decades. China, for instance, requires an annual expenditure averaging close to US$20 billion on nuclear infrastructure by 2050, representing a nearly twofold increase compared to the average observed during the 2010s (Aghahosseini et al., 2023; Vujić et al., 2012). Conversely, other EMDEs witness a tripling of investment, reaching approximately US$25 billion per year, on average. In contrast to advanced economies, the imperative for investment in these nations is more pronounced in the period leading up to 2035 (Bhattacharyya et al., 2023; Khaleel et al., 2024). Thus, nuclear energy, despite its advantages as a low-carbon energy source, faces notable challenges. High capital costs and long deployment timelines, driven by complex construction and regulatory requirements, often hinder its adoption. The management of radioactive waste remains a costly and contentious issue, while safety concerns, shaped by historical incidents, continue to influence public perception. Additionally, reliance on uranium, with its geographically concentrated supply, raises geopolitical and environmental concerns. Nuclear power also competes with the rapidly advancing and cost-effective renewable energy sector, while decommissioning aging plants poses long-term financial and logistical burdens. Addressing these limitations through advanced technologies, public engagement, and international collaboration is crucial for enhancing nuclear energy's role in sustainable energy transitions. Technologies for sustainability in nuclear energy production The pursuit of sustainability in nuclear energy production has been supported by advancements in innovative technologies that enhance efficiency, safety, and environmental compatibility (Aktekin et al., 2024; Ali et al., 2024; Zheng et al., 2024; Khan et al., 2017). These technologies are crucial for positioning nuclear power as a key contributor to clean and sustainable energy transitions. Below are some of the most impactful technologies in this domain: Advanced nuclear reactors: Small modular reactors (SMRs): SMRs are compact, scalable, and safer than traditional large-scale reactors. Their modular design allows for deployment in remote locations, making them suitable for decentralized energy systems. Generation IV reactors: These reactors incorporate advanced cooling systems and fuel cycles to improve efficiency, safety, and waste reduction. Examples include sodium-cooled fast reactors and gas-cooled fast reactors. Thorium-based reactors: Thorium fuel cycle reactors use thorium-232 as an alternative to uranium, offering a more abundant and sustainable fuel source. Thorium reactors produce less nuclear waste and have a lower risk of proliferation. Fusion energy: Although still in the experimental stage, nuclear fusion promises to be a game-changing technology. Fusion produces minimal radioactive waste and harnesses abundant fuel sources like deuterium and tritium, making it a virtually limitless and clean energy solution. Molten salt reactors (MSRs): MSRs use liquid fuels or coolants, such as molten salts, which operate at lower pressures and higher temperatures. These reactors are inherently safer and have the capability to utilize a variety of fuel types, including spent nuclear fuel and thorium. Reactor safety enhancements: Passive safety systems: These systems enhance reactor safety by using natural forces like gravity, natural convection, or condensation to cool the reactor core without human intervention. Digital twin technologies: Digital simulations and monitoring of reactor systems allow for predictive maintenance and real-time safety management. Nuclear waste management technologies Fast reactors: These reactors can recycle spent fuel, reducing the volume and radioactivity of nuclear waste. Deep geological repositories: Advances in geotechnical engineering have improved the safety of long-term waste storage in deep geological formations. Hybrid nuclear-renewable systems: Combining nuclear power with renewable energy sources like wind and solar can optimize energy production and grid stability. Hybrid systems leverage the reliability of nuclear energy with the intermittency of renewables for a balanced, low-carbon energy mix. Artificial intelligence (AI) and machine learning: AI and machine learning technologies are being deployed to enhance reactor performance, optimize fuel usage, and improve operational safety. Predictive analytics also play a critical role in maintenance and risk assessment. Fuel advancements: High-assay low-enriched uranium (HALEU): HALEU fuels enable reactors to operate more efficiently and reduce waste. Accident-tolerant fuels (ATFs): These are designed to withstand extreme conditions, reducing the likelihood of core damage during accidents. Integrated energy systems: Nuclear reactors are increasingly being used for purposes beyond electricity generation, such as hydrogen production, district heating, and desalination. The integration of digital technologies, including AI and machine learning, coupled with fuel advancements like HALEU and accident-tolerant fuels, highlights the continuous evolution of the nuclear sector. These innovations not only enhance efficiency and safety but also expand the applications of nuclear energy beyond electricity generation to include hydrogen production, desalination, and district heating. Despite these technological advancements, the sustainable deployment of nuclear energy requires robust policy frameworks, increased investments, and public acceptance. Addressing these challenges is critical to unlocking the full potential of nuclear power in achieving global energy security and NZE by 2050. [...] Discussion and policy implications Nuclear power presents a compelling case as a sustainable energy source owing to its several key advantages. Its high-energy density allows for substantial electricity generation from minimal fuel, enabling continuous operation, unlike intermittent renewables, such as solar and wind (Rekik and El Alimi, 2023a, 2023b), thus contributing significantly to grid stability (Cramer et al., 2023). Furthermore, nuclear power is a crucial tool for emissions reduction, boasting virtually no greenhouse gas emissions during operation. Although lifecycle emissions associated with fuel processing and plant construction exist, they remain comparable to or lower than those of renewables. Several studies have reported on the energy production capabilities of nuclear power and its contribution to reducing greenhouse gas emissions compared to other energy sources. A key aspect of these analyses is quantifying the potential contribution of nuclear power to reducing greenhouse gas emissions and achieving net zero targets. However, direct comparison of reported data can be challenging due to variations in model assumptions, geographic scope, and time horizons.  [...] From another perspective, radioactive waste generation poses a significant challenge to nuclear power because of its long-term hazardous nature. This necessitates meticulous management and disposal strategies to mitigate potential social impacts. These impacts arise from perceived or actual risks to human health and the environment, fueling public anxiety and opposition to nuclear power, which is often expressed through protests and legal action (Kyne and Bolin, 2016; Nilsuwankosit, 2017; Ram Mohan and Namboodhiry, 2020). Additionally, communities near waste sites can experience stigmatization, resulting in decreased property values and social isolation. The persistent nature of radioactive waste also raises intergenerational equity issues, burdening future generations with its management (Deng et al., 2020; Mason-Renton and Luginaah, 2019). Thus, transparent communication and stakeholder engagement are crucial for building public trust and ensuring responsible radioactive waste management (Dungan et al., 2021; Sančanin and Penjišević, 2023). There are various radioactive waste disposal pathways, each with unique social and technical considerations. Deep geological disposal, an internationally favored method for high-level waste disposal, involves burying waste deep underground for long-term isolation. Interim storage provides a secure temporary holding until a permanent solution is obtained (Chapman, 1992; Grambow, 2022). Reprocessing spent nuclear fuel recovers reusable materials, reducing high-level waste but creating lower-level waste. Advanced reactor technologies aim to minimize waste and improve safety, potentially converting long-lived isotopes into shorter-lived isotopes (Dixon et al., 2020; Englert and Pistner, 2023). Choosing a disposal pathway requires careful evaluation of factors, such as waste type and volume, geology, feasibility, cost, and public acceptance, often leading to a combined approach. Ongoing community engagement and addressing concerns are essential to safe and responsible waste management. Effective management and disposal of this waste require advanced technological solutions, robust regulatory frameworks, and long-term planning to ensure safety and sustainability (Abdelsalam et al., 2024; Rekik and El Alimi, 2024a), Moreover, its relatively small land footprint compared to other energy sources, especially solar and wind farms, minimizes the ecosystem impact and makes it a sustainable option in densely populated areas (Poinssot et al., 2016; Sadiq et al., 2022). Nuclear power also enhances energy security by reducing reliance on fossil fuels, which is particularly valuable in countries with limited domestic resources (Cramer et al., 2023; Ichord Jr., 2022). Additionally, nuclear power exhibits synergy with other clean technologies, providing a stable baseload complementing variable renewables and facilitating hydrogen production for diverse energy applications (Abdelsalam et al., 2024; El-Emam and Subki, 2021; Salam and Khan, 2018; Rekik, 2024; Rekik and El Alimi, 2024e). Finally, ongoing advancements in reactor design, such as SMRs, promise enhanced safety, reduced costs, and greater deployment flexibility, further solidifying the role of nuclear power in decarbonizing the electricity sector (Aunedi et al., 2023). Supportive policies and international cooperation are essential for fully realizing the potential of nuclear energy. Streamlined licensing and regulatory frameworks are crucial for reducing deployment time and costs and ensuring that safety standards are met efficiently (Gungor and Sari, 2022; Jewell et al., 2019). Furthermore, incentivizing investments through financial tools such as tax credits and loan guarantees can attract private capital and create a level-playing field for nuclear power (Decker and Rauhut, 2021; Nian and Hari, 2017; Zimmermann and Keles, 2023). Addressing public perception through education and engagement is equally important for building trust and acceptance. Moreover, international cooperation is vital in several respects. The disposal of radioactive waste remains a complex issue, requiring careful long-term management and securing geological repositories to prevent environmental contamination owing to the long half-life of some isotopes. Furthermore, while modern reactors incorporate advanced safety features, the potential for accidents such as Chernobyl and Fukushima remains a concern because of the potential for widespread radiation release and long-term health consequences (Denning and Mubayi, 2016; Högberg, 2013; Wheatley et al., 2016). Moreover, the high initial costs associated with design, construction, and licensing present significant barriers to new nuclear projects, particularly in developing countries. In addition, the risk of nuclear proliferation, in which technology intended for peaceful energy production is diverted for weapons development, necessitates stringent international safeguards, as highlighted by following reference. Public perception also plays a crucial role because negative opinions and concerns about safety and waste disposal can create opposition to new projects. Finally, the decommissioning of nuclear plants at the end of their operational life is a complex and costly process that requires substantial resources and expertise to dismantle reactors and manage radioactive materials. [...] Conclusion The role of nuclear power in sustainable energy transition is multifaceted and significant. As nations worldwide strive to transition toward more environmentally friendly energy systems, nuclear power has emerged as a crucial component of the decarbonization journey. Its capacity to provide low-carbon electricity, mitigate climate change, and contribute to energy security underscores its importance in the broader context of sustainable energy transitions. Despite this, challenges such as safety, waste management, and public perception must be addressed to fully harness the potential of nuclear power to achieve sustainability goals. By leveraging policy frameworks, technological innovations, and international cooperation, nuclear power can play a vital role in shaping the future of sustainable energy transition on a global scale. In this context, EMDEs exert a substantial influence on global growth, collectively accounting for over 90% of the aggregate, with China positioned to emerge as the foremost nuclear power producer before 2030. Concurrently, advanced economies have witnessed a notable 10% increase in their nuclear power capacity. This augmentation is attributed to the commissioning of new facilities, which offset retirements, manifestly observed in nations such as the United States, France, the United Kingdom, and Canada. Furthermore, there is a marked escalation in annual global investment in nuclear power, surging from US$30 billion throughout the 2010s to surpass US$100 billion by 2030. This upward trajectory is robustly sustained, remaining above US$80 billion by 2050. In conclusion, the remarkable decline in the levelized cost of electricity (LCOE) for solar PV and wind power over the past decade has positioned renewable energy as a cost-competitive and viable alternative to fossil fuels in many regions. The over 80% reduction in LCOE for utility-scale solar PV from 2010 to 2022 exemplifies the economic feasibility of renewables. Concurrently, the steady growth in renewable energy capacity, spearheaded by solar and wind energy, underscores their critical role in the global energy transition. With renewable electricity capacity surpassing 3300 GW in 2023 and accounting for over one-third of the global power mix, renewable energy is undeniably at the forefront of efforts to achieve a sustainable, low-carbon energy future. Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.FundingThe authors received no financial support for the research, authorship, and/or publication of this article.ORCID iDSassi Rekik https://orcid.org/0000-0001-5224-4152Supplemental materialSupplemental material for this article is available online.ReferencesAbbasi K, Jiao Z, Shahbaz M, et al.

Brazil's BRICS+ presidency ahead of the summit in Rio de Janeiro Brazil is using its BRICS+ presidency in 2025 to promote a more inclusive and sustainable world order as a pragmatic mediator for developing and emerging countries and to preserve its independence in foreign policy. For Europe, this presents both challenges due to the growing heterogeneity and independence of the BRICS+ group, as well as opportunities for a strategic partnership with Brazil, for example through the EU-Mercosur agreement and joint projects in the areas of climate, health, and technology. It is crucial that Europe recognizes Brazil as an equal partner in order to jointly set global standards and actively shape the international order. The Brazilian BRICS+ presidency With the assumption of the BRICS+ presidency in January 2025, the first following the expansion of the alliance, Brazil is once again assuming a vital role on the international stage after the G20 presidency in the previous year. Under the motto "Strengthening cooperation in the Global South for more inclusive and sustainable governance", Brazil is setting clear priorities: global health cooperation, trade and finance, climate change, regulation of artificial intelligence, multilateral peace architecture and institutional development of the BRICS+ bloc. Brazil is advancing the latter, for example, through events such as the 11th Parliamentary Forum in Brasília in June 2025, which aims to deepen political dialog and parliamentary cooperation and promote the democratic legitimacy of the bloc. Between February and July, the Brazilian Presidency set a broad agenda with over one hundred ministerial and technical meetings. The selected topics reflect the interests of many emerging and developing countries and illustrate Brazil's claim to function as a bridge builder between the so-called "Global South" (a controversial term due to its vagueness and homogenization) and the established industrialized countries. Foreign policy pragmatism as a leitmotif Brazil's foreign policy has historically been characterized by pragmatism and a clear focus on national interests. For decades, the country has pursued a strategy aimed at preserving the greatest possible autonomy and not subordinating itself to the priorities of the major powers. This attitude is currently particularly evident: Brazil has not joined the Chinese Belt and Road Initiative and voted against the inclusion of Nicaragua and Venezuela in the BRICS. Brazil's great dependence on its most important trading partner China is now also being viewed critically in parts of Brazilian politics and diplomacy. However, the government in Brasília continues to strictly refuse to be pigeonholed or categorized into a fixed camp, instead opting for flexibility and openness - a strategy that ensures maximum freedom of action. In contrast to countries such as Mexico, which is more closely tied to the USA due to its geographical location and economic ties, Brazil can balance its foreign policy between different centers of power and represent its interests with confidence. Heterogeneity and dynamics of the BRICS+ The BRICS+ group is anything but homogeneous. The member states are democracies, autocracies and dictatorships and disagree on a variety of issues. For example, whether BRICS+ should function as an anti-Western force or serve as a platform for a reformed, more inclusive world order. The refusal of President Xi Jinping and President Vladimir Putin to attend the BRICS+ summit in Rio de Janeiro on July 6-7 highlights the internal tensions and heterogeneity of the alliance of states. If Putin could take part in the summit virtually, there is speculation in Brasília about the reasons for Xi's refusal. Is the Chinese partner annoyed by Brazil's rejection of the Belt and Road Initiative or are they bothered by India's prominent participation in Rio de Janeiro? Chinese voices justify Xi's absence with the fact that he has already met President Lula twice in less than a year, once at the G20 summit in Brazil in 2024 and most recently at the China-CELAC summit in Beijing in May. The Egyptian government also recently announced that President Al-Sisi will not be traveling to the summit due to the situation in the Middle East. Other high-ranking guests such as Mexican President Sheinbaum and Turkish President Erdoğan have also announced that they will not be traveling to Rio. An Iranian delegation has not yet been confirmed. On the one hand, the absence of the two heavyweights, Xi and Putin, could weaken the international appeal and political weight of the meeting, as the media attention and the signal effect of such a summit depend on the presence of the heads of state. On the other hand, this constellation opens up new scope for action, especially for those countries that are not clearly anti-Western - above all Brazil, India, and South Africa. These countries could use the opportunity to set their own priorities and campaign for a more pragmatic, more open orientation of the BRICS+. Brazil in particular, which traditionally pursues an interest-oriented and pragmatic foreign policy, sees itself in the role of a mediator who does not want to commit the bloc to a confrontation with the West. Rather, Brazilian diplomacy is concerned with using BRICS+ as a platform for reforming the international order without submitting to the priorities of individual major powers. The fact that Brazil has neither joined China's Belt and Road Initiative nor supported Venezuela's admission to the BRICS underlines this independent and active course of non-alignment. Within Brazilian politics, academia and diplomacy, the increasing heterogeneity of the BRICS+ group is being increasingly criticized. Although the expansion to include new members such as Indonesia and Ethiopia has increased the global reach, it has also exacerbated internal conflicts of interest. There are voices in Brasília who fear that the bloc's coherence and ability to act could suffer as a result of this diversity. At the same time, however, diversity also offers opportunities for Brazil: it enables Brazil to distinguish itself as a constructive force and promote dialog between different political and economic systems. However, it is questionable whether the current government under President Luiz Inácio Lula da Silva (PT) will be able to take advantage of this opportunity. Multipolarity, geography and new zones of influence The multipolar world order that is currently emerging following the end of US unipolar dominance is tending towards instability. Several centers of power are competing for influence, the complexity of international relations is increasing, and the risk of conflict is rising. In the course of these developments, the BRICS+ are also gaining relevance. We are experiencing a time in which zones of influence such as those actively pursued by the USA and Russia are once again gaining in importance - be it in Eastern Europe, the Middle East or in North and South America. In this environment, Brazil is pursuing a "hedging" strategy: it is skillfully balancing between the major powers without committing itself, thus preserving its foreign policy autonomy. A balancing act that is becoming increasingly difficult, as demonstrated by the recurring critical questions from Europe about Brazil's BRICS+ membership. Brazilian diplomatic pragmatism is difficult to reconcile with the European idea of a value-based multilateral world order and is therefore difficult for Europeans to understand. Brazil's geographical location - as the largest nation in South America, with access to the Atlantic and as a bridge between North and South - also has a major influence on its foreign policy stance. Geography plays a key role in understanding certain political actions. Its distance from the global centers of conflict allows Brazil to take on a moderate, mediating role. While many conflicts in other parts of the world are dominated by geopolitical tensions, Brazil can often act more neutrally and constructively. Brazil's wealth of raw materials and the associated potential, as well as its special geographical and strategic position, make it an important player in international diplomacy and a key player for Europe. Resources, narratives, and soft power In the 21st century, power is no longer measured exclusively in terms of military superiority. Rather, access to natural resources - especially rare earths -, economic innovation and the ability to shape global narratives are at the heart of the modern exercise of power. Soft power, i.e., influence through diplomacy, cultural exchange, and the targeted shaping of narratives, has become a central instrument of international politics. A striking example of the importance of soft power was demonstrated during the COVID-19 pandemic: China and Russia made targeted use of vaccine diplomacy to expand their influence in Latin America. The BRICS alliance also gained in importance and stood for cooperation in the so-called "Global South". Europe, but also the USA, on the other hand, was initially perceived in the region as cautious and concerned with its own advantage. The EU's so-called "vaccine nationalism" at the beginning of the pandemic had a lasting impact on the trust of many countries in European solidarity. This experience is still present in Latin American memory today. Brazil has made great progress in its own vaccine production in recent years and has established itself as a regional player in the healthcare sector. Nevertheless, the country is still dependent on international supply chains, particularly for the procurement of precursors and technologies. The opening up to China and Russia in the healthcare sector as a result of vaccine diplomacy has created additional opportunities for these players to strengthen their presence and influence in Brazil and the region. Opportunities for a strategic partnership with Europe It is precisely against this backdrop that Europe must seek new opportunities to put its relationship with Brazil on a future-oriented and partnership-based footing. The EU has considerable strengths: economic and technological innovation, diplomatic experience, and the ability to set international standards. With the "Strategic Compass", the EU has further developed its foreign policy instruments and focuses on the four guiding principles of "Acting, Securing, Investing, Partnering". However, in order to be successful in global competition, Europe must act faster and be prepared to meet Brazil on an equal footing and take it seriously as an equal partner. The EU should make targeted use of its economic, technological, and diplomatic strengths for sustainable and strategic cooperation. This includes the promotion of joint research projects, technology and science transfer and support for the development of local production capacities - particularly in the healthcare sector, but also in areas such as sustainable raw material extraction, digitalization, and green transformation. Especially at a time when the reliability of the USA as a partner is being questioned for good reasons, Europe and Germany can score points with reliability, transparency, and long-term commitment. In addition to the EU-CELAC summit in November 2025, another important instrument in this context would be to hold renewed German-Brazilian government consultations before the Brazilian presidential and parliamentary elections in the fall of 2026. The conclusion of the EU-Mercosur agreement, cooperation on renewable energies, the promotion of sustainable agriculture, the deepening of cooperation in the defense industry and the co-design of global health standards are fields in which Europe and Brazil can jointly set standards. At the same time, it is essential for the EU to strengthen its own raw material security and secure access to key technologies and rare earths in order to maintain its own ability to act. In the long term, a close partnership with Brazil offers the EU and Germany the opportunity not only to pursue economic interests, but also to jointly develop global standards and actively help shape, reform and strengthen the rules-based international order. However, this requires Europe to respect Brazil as an independent, equal player and to recognize and consider the country's specific interests and experiences. The latter also applies equally to the other side. Symbolic gestures such as Brazilian President Lula's participation in the military parade in Moscow on May 9 to mark the 80th anniversary of the end of the war are detrimental to cooperation with Europe. They hinder trusting, forward-looking cooperation between Europe and Brazil, which could bring great benefits to both sides and contribute to stabilizing the multilateral world order. Outlook: COP30 and Brazil's global agenda In November 2025, Brazil will host the UN Climate Change Conference COP30 in the Amazon region in Belém in the final phase of its two-year leadership role - a further step towards positioning itself as a global player in climate and environmental policy and acting as a mediator between the so-called "Global South" and the industrialized nations. The Brazilian agenda focuses on sustainable development, the protection of biodiversity and the promotion of renewable energies. This underlines Brazil's claim to assume not only regional but also global responsibility. The COP30 offers Europe and Brazil a further opportunity to intensify their cooperation on climate protection and related issues and to provide joint impetus for a more sustainable world order. Conclusion The emerging multipolar world order is more unstable and prone to conflict than the unipolar phase before. Brazil acts skillfully in the field of tension between the great powers and uses its resources and diplomatic flexibility to secure national interests. Europe should recognize this reality and actively shape its partnership with Brazil to its own advantage. The influence of the BRICS+ alliance should be viewed soberly - neither overestimated nor underestimated, but with a realistic assessment of its importance and potential. Only through strategic engagement and a little more pragmatism can the EU and Germany safeguard their interests and contribute to stabilizing an increasingly fragmented world. The BRICS+ summit and the upcoming COP30 are touchstones for Brazil's and Europe's ability to help shape a new, complex world order and act on an

Abstract The international system is currently undergoing a process of reconfiguration that is having an impact on all areas of global development. In this process of reordering power relations, there is a tendency to move towards multipolarity, leaving behind the unipolar coalition established after the Second World War. In this context, several emerging powers are gaining increasing international power, which has led to changes in the hierarchy of power on the international geopolitical chessboard. Such is the case of the People's Republic of China, which has established itself not only as a power of great impact and relevance in the Asian region, but also in the entire international system. Namely, the management of the government and the Party in terms of innovation, industrialization, informatization, productivity, expansion and internationalization of its economic model, positions this country as the most dynamic center of the international economy. Evidencing that alternative models to the capitalist system are possible and viable, which strengthens the trend towards a systemic transition and multipolarity in the International System Introduction In the last two decades, a set of geopolitical and geoeconomic tensions and conflicts have become evident, with significant implications extending throughout the International System. As a result, we are currently experiencing a convulsion of the established order, giving way to a process of new global reconfigurations. In this context, several researchers and academics such as Jorge Casals, Leyde Rodríguez, Juan Sebastián Schulz, among others, have noted that these conditions have led to a crisis and hegemonic transition process, with a trend toward multipolarity in which the Asia-Pacific region is gaining increasing relevance. This article, titled "The International Reconfiguration’s Process Towards Multipolarity: The Role of China as an Emerging Power," is dedicated to analyzing the position of this country within the current international reconfiguration of power. Accordingly, the first section will systematize some essential guidelines to understand the current crisis and the decline of the hegemonic order established in the post-World War II period. The second section will address China's positioning amid the international reconfiguration of power. In this regard, it is important to note that China's rapid rise highlights how development management aligned with the Sustainable Development Goals can lead to a shift in the paradigm of international relations, as well as power reconfigurations that challenge the current balance of forces. Thus, it can be affirmed that China's rise constitutes a decisive element within the current trend toward multipolarity. DevelopmentNew International Order: Approaches to the Multipolar Reconfiguration of the International System The current international context is marked by a process of crisis. This crisis reflects the fact that the world order no longer aligns with the correlation of forces that gave rise to it during the post-World War II period. It is not a circumstantial crisis, but rather the interlinking of various interconnected crises that span across all sectors of life. That is to say, the effects of one crisis often become the causes of another, involving economic, political, social, cultural, ethical, moral, technological, commercial, and environmental components. In other words, it is a structural and systemic crisis—one that cannot be resolved unless a similarly systemic transformation occurs. To gain greater clarity, it is important to consider that the consolidation of the capitalist system brought about the process of globalization. This, in turn, introduced large-scale production and technological development capable of increasing output. This process, along with other characteristics of the system, has exponentially accelerated social inequalities between developed and developing countries. It has also led to strategic tensions over the control of resources, raw materials, and inputs, resulting in geopolitical conflicts. Furthermore, the capitalist system has imposed an extremely high environmental cost, demonstrating that it is exceeding both its own limits and those of the planet. Specifically, in its constant pursuit of profit and maximization of gains, negative environmental impacts are not factored into cost-benefit analyses, leading to widespread environmental degradation. Among other harms caused by the system, we observe a decline in investment rates, an increase in public debt, loss of autonomy in monetary policy, rising unemployment levels, reductions in real wages, and growing inequality, among others. In short, capitalism has become an unsustainable system whose primary concern is profit generation—something that is currently entirely incompatible with environmental preservation and the responsible use of natural resources. Therefore, it can be affirmed that some of its most alarming effects include: vast amounts of currency without backing, increasingly concentrated in fewer hands; acceleration of capital concentration in the West; rising military expenditures; and environmental pollution and destruction (Casals, J., 2023). On the other hand, it is necessary to clarify that, for a particular state to be considered hegemonic, it must not only exert its influence predominantly within the system of international relations; its hegemonic role must also be linked to the founding and establishment of a universally accepted concept of world order. That is, the majority of other states must recognize it as such and identify with the model promoted by the hegemon. Therefore, it is not merely a matter of a hierarchical order among states, but rather the adoption of a dominant model of production that involves those states. As a result, certain mechanisms or general rules of conduct are established for the participating states. For this reason, a hegemonic crisis involving the dominant actor in the system of international relations leads to a crisis in the social, economic, political, and institutional structures upon which that actor’s dominance was built. In light of these elements, we currently observe a set of powers within the International System that are vying to establish a new distribution of power—one that moves away from the unipolar coalition led by the United States following World War II. From this perspective, Juan Sebastián Schulz asserts: “A hegemonic crisis occurs when the existing hegemonic state lacks either the means or the will to continue steering the interstate system in a direction broadly perceived as favorable—not only for its own power, but also for the collective power of the dominant groups within the system.” (Schulz, J. S., 2022) As a result, strategic alliances have been formed and new power groups have emerged that influence international relations.These blocs are precisely what the new polarity is forming around, increasingly reinforcing the trend toward multipolarity. This is a system in which hegemonic influence is not determined by a single power, but by two, three, or more. In this regard, Juan Sebastián Schulz further notes that a process of insubordination is becoming evident, particularly in the Western peripheries. As a consequence, several countries have begun to criticize the configuration of the contemporary world order, initiating efforts to organize and propose alternative models (Schulz, J. S., 2022). This reveals the emergence of a new kind of power hierarchy, generating a global order in which a diversity of forces and actors prevails. In this context, China has experienced rapid growth, thereby contributing to the trend toward multipolarity. While this does not imply that the United States will cease to be one of the central powers in the system of international relations—given its considerable global influence—it is evident that there is a noticeable decline in the dominance it held during the unipolar era that emerged after the collapse of the USSR in 1991. This process of intersystemic transition unfolds in various phases. First, there is an observable economic transition marked by a shift in the center of gravity of the global economy toward emerging and developing economies. This shift is accompanied by a necessary technological transition, characterized by a new struggle—this time to lead the technological revolution. These changes, in turn, must be supported by a political transition. Currently, countries from the Global South have gained increasing prominence on the international stage [1]. From this foundation, a geopolitical transition is also underway, where the center of gravity and decision-making—once concentrated in the Anglo-Saxon West—is shifting toward the Asia-Pacific region. Finally, a cultural or civilizational transition is taking place, wherein the previously dominant value system is giving way to the rise of a new worldview. Based on this, the phases of the transition process can be outlined as follows: Existence of a stable order that brings together the majority of nation-states in the International System. - A crisis of legitimacy begins to affect the established global order. - A deconcentration and delegitimization of power emerges, impacting the hegemonic power. - An arms race and formation of alliances ensue in an attempt to preserve the hierarchical order by any means. This leads to a widespread crisis and the rise and emergence of new actors. - A necessary resolution of the international crisis. - Renewal of the system. (Schulz, J. S., 2022) In light of the above, it can be stated that a “new international order” is taking shape. Its manifestations are multifaceted, such as: - The rise of movements and associations of states that serve as alternatives to the neoliberal order. - Emerging powers like China and Russia are gaining strength in various sectors of the international geopolitical arena. - Russia's confrontation with NATO in the context of the conflict with Ukraine. - Sanctions imposed by the United States on various NATO and European Union countries have strengthened the BRICS nations. - The incorporation of new members into BRICS can be seen as an attempt to counterbalance the economic and political dominance of the United States and the European Union. - The expansion of anti-imperialist and anti-neoliberal integration mechanisms that promote South-South cooperation, such as the G-77 + China group. - The financial sanctions imposed by the West on Russia in the context of the Ukraine conflict have sparked a debate about the viability of the international monetary system and the role of the U.S. dollar as a reserve currency. - China and Russia conduct transactions in yuan and sell oil in this currency to Iran, Venezuela, and Gulf countries. China has increased its economic and political influence in the world, which can be seen as a challenge to U.S. hegemony. Its leadership within BRICS and its growing role in the global economy may be indicators of a shift in the balance of power. All these developments reflect a growing awareness within the International System of States regarding the importance of international cooperation to address global challenges such as the climate crisis, pandemics, and food security. They also serve as indicators that a transformation is underway in the way countries interact with each other, resulting in a shift in the economic, political, and strategic center of gravity. In this context, the United States has unleashed a global hybrid war as a desperate attempt to defend and maintain its hegemonic position, which once appeared unshakable in the postwar world. To this end, it has targeted China, as the latter represents its main threat in the economic and scientific-technological order. From this perspective, tensions between the United States and China have significantly deteriorated since the Republican administration of President Donald Trump. Beginning in 2017, his policy took on an aggressive stance toward China, manifesting through a trade war and economic attacks aimed at preserving U.S. global hegemony. This demonstrates that, in response to a process of decline already underway, nationalist and protectionist efforts intensified in the U.S., with policies targeting some of the emerging pillars of the crisis-ridden world order—China being a primary example. Under the administration of Joseph Biden, the focus shifted toward competition, emphasizing the commitment to protect U.S. sovereignty from potential Chinese threats. A significant shift in U.S. foreign policy toward Taiwan became evident with the approval of arms sales to Taiwan in August 2023, which escalated tensions in the region (Collective of Authors). Furthermore, in recent years, the United States has increasingly worked to generate geopolitical and geoeconomic motivations aimed at fostering tensions between China and Russia, potentially sparking conflict between the two. It has strengthened alliances with neighboring countries of these powers—most notably Taiwan and Ukraine—which has triggered concerns and tensions in both nations. A containment policy has also been deployed, including the imposition of trade barriers and tariffs on Chinese products; restricting Chinese companies’ access to U.S. technology and markets; and promoting the diversification of supply chains to reduce dependence on China. Nevertheless, the ongoing sanctions and restrictions have only served to reaffirm the shared survival interests of both powers, strengthening corporate ties and relations between them. These actions also reflect the growing concern among U.S. power groups over the decline of their hegemonic dominance. The Emergence of China and Its Role in the Transition Toward Multipolarity In a previous article titled "The Synergy Between Economy and Environment in China Through the Achievement of the Sustainable Development Goals," (‘La sinergia entre economía y medio ambiente en China mediante la consecución de los Objetivos de Desarrollo Sostenible’) the process of socioeconomic transformations experienced in the People's Republic of China over the past decade was discussed. These transformations have been primarily aimed at revitalizing the nation in preparation for its centenary in 2049. This strategy is rooted in aligning the Centenary Goals with the Sustainable Development Goals (SDGs) set for 2030, under the leadership of the Communist Party and the momentum driven by President Xi Jinping. The results of this strategy have had an impact not only on the Asian Giant itself—now a decisive actor in the Asian region—but also on the international order as a whole. As a result, China has emerged as a powerful rising power, with promising prospects for further elevating its development standards. This is backed by sustained GDP growth, averaging between 6% and 8% annually, indicating a robust economy. In addition, China holds vast foreign exchange reserves, granting it economic stability and the capacity to withstand potential external shocks. It also invests heavily in modern infrastructure and cutting-edge sectors such as artificial intelligence, 5G technology, and renewable energy—all of which enhance its competitiveness and lay the groundwork for long-term sustainable growth (Lagarde, CH). Nonetheless, China has also had to confront significant challenges in its gradual and progressive approach to the desired development model. Among these is the environmental cost associated with its rapid economic growth. For instance, China still experiences high levels of greenhouse gas (GHG) emissions, along with air, water, and soil pollution. In response, measures have been implemented such as the establishment of a national monitoring network and the replacement of coal heating systems in Beijing. Efforts have also been made to purify water resources polluted by industrial processes, and imports of solid waste have been reduced to help decontaminate soils affected by industrial and agricultural activities (González, R., 2023). In general, the development of renewable energy and a circular economy model is being promoted to enable a gradual transition toward a green economy, grounded in the concept of an ecological civilization. For this reason, China’s new era is committed to scientific and technological innovation as a means of driving economic growth that is both sustainable and capable of ensuring a higher quality of life for its population. This, in turn, leads gradually toward a new model of political leadership and economic management. In this regard, Jin Keyu, Professor of Economics at the London School of Economics and Political Science (LSE), has stated that “trillions of dollars of investment are needed for the global green transition, and China is going to play an essential role in that transformation” (Feingold, S., 2024). Based on the aforementioned elements, various authors such as Dr. C. Charles Pennaforte, Dr. C. Juan Sebastián Schulz, Dr. C. Eduardo Regalado Florido, among others, have indicated that the millenary nation represents a threat to the hegemony held by the United States since World War II. Consequently, it is recognized that a process of hegemonic crisis and transition is currently underway, with the Asia-Pacific region emerging as the center of gravity of the global power, thereby contributing to the multipolar transformation of the International System. The authors of “Is China Changing the World?” argue that “market socialism with “Chinese characteristics” must gradually and more clearly diverge from capitalism if it is to embody a genuinely alternative path for all of humanity.” In pursuit of this goal, China bases its policy of peaceful coexistence on five fundamental principles:Respect for sovereignty and territorial integrity, regardless of a country's size, power, or wealth. Mutual non-aggression Non-interference in the internal affairs of other countries, acknowledging that each nation has the right to freely choose its own social system and path of development. Equality and mutual benefit Peaceful coexistence. (Herrera, R.; Long, Z.; and Andréani, T., 2023) The rise of China as a major international power under these principles has been consolidating since 2012 under the leadership of Xi Jinping and the Communist Party of China (CPC), gaining particular momentum from 2020 to the present. Thus, China has not only become the leading power within the Asian regional balance but has also expanded its presence across Europe, Africa, and Latin America—primarily through loans, investments, and multilateral cooperation initiatives such as the Forum on China-Africa Cooperation (FOCAC) in Africa and the China-CELAC Forum in Latin America. In addition, China has positioned itself as a leader in several sectors, and it is projected that its economy may surpass that of the United States, increasing its Gross Domestic Product (Rodríguez, L., 2022). It has also undergone a process of opening up, energizing both its international trade and its overall foreign relations, all under the control of the Government and the Party. This, combined with its rise and development initiatives, has made China a focal point of interest for many countries within the International System seeking to jointly advance projects based on cooperation, the principle of shared advantage, and multilateralism. In this regard, the white paper "China and the World in the New Era," published by the Central Committee of the Communist Party of China in 2019, states: “The world is moving rapidly toward multipolarity, diverse models of modern development, and collaboration in global governance. It is now impossible for a single country or bloc of countries to dominate world affairs. Stability, peace, and development have become the common aspirations of the international community.” (People’s Republic of China, 2019. Quoted in Schulz, J. S., 2022) Undoubtedly, this rise has become a source of concern for U.S. power groups, which have increasingly applied geostrategic pressure. Notably, the United States has strengthened military alliances with India, Japan, and Australia in an effort to encircle China and attempt to control or obstruct its maritime routes—this also being a manifestation of the intensification of the imperialist arms race. Nonetheless, China has maintained its development strategy and, as part of it, has strengthened its diplomatic network and its relations with multiple countries across all world regions. For all these reasons, China has become the most dynamic center of the global economy. Notably, it went from representing 4% of global GDP in 1960 to 16% in 2020—undeniable evidence of rapid economic growth. Moreover, it has become the world’s largest exporter of goods and also the leading importer, establishing itself as a major industrial power. In this regard, United Nations data reveal that China leads global industrial production, accounting for 30% of the total. This figure surpasses other industrial powers such as the United States (16%), Japan (7%), Germany (5.7%), and South Korea (3.2%) (Schulz, J. S., 2022). In addition, China has remained the world’s leading manufacturing power for approximately 15 consecutive years, according to statements from the Ministry of Industry and Information Technology at the beginning of this year. This sector alone has contributed over 40% to overall growth. Likewise, in 2024, China experienced a significant increase in foreign investment, reflecting its interest in strengthening international cooperation for development. Efforts are also underway for urban renewal in 2024, with around 60,000 projects being implemented across various cities. These initiatives are primarily aimed at transforming underdeveloped neighborhoods and creating smarter urban areas (Embassy of the Republic of Cuba in the People's Republic of China, 2025). In this regard, the following graphs illustrate the value of China’s international trade during the 2016–2024 period, highlighting a strong presence of exports compared to imports. A second chart shows China's global export share, where it holds a dominant position.   Thus, China has risen as a center of power in the international system, with leadership not only in the economic domain but also in science and technology. At the same time, it has promoted a series of investments and a process of internationalizing its national currency. Accordingly, the Asian Giant offers an alternative model of development—one that is more comprehensive and sustainable—allowing it to propel the new phase of Chinese development. This phase aims not only to fulfill the dream of national rejuvenation but also to ensure the survival of its unique political, economic, and social model. Nevertheless, the significant challenges of sustaining growth cannot be overlooked. From this perspective, experts believe that new avenues of growth will be necessary for China to maintain the trajectory it has been experiencing. Specifically, the country must continue expanding its industrial sector while strengthening areas such as artificial intelligence, digital financial services, and green technologies (Feingold, S., 2024). It is also important to highlight the projected continuity and leadership of the Chinese government, with Xi Jinping identified as a key figure in the implementation of the Sustainable Development Goals (SDGs) in China, in conjunction with the socioeconomic transformation strategy toward the 2049 centenary. This has been pursued through the defense of multilateralism, economic openness, and international integration and cooperation in support of global development. Conclusions In light of the above, a decline in U.S. hegemony can be observed, even though this process is not linear—nor is it certain whether any single power or coalition has come to occupy a hegemonic position. What is clear, however, is the existence of a trend toward multipolarity, driven by emerging powers and the strategic ties they are establishing. This is giving rise to a non-hegemonic reconfiguration of power blocs, which are building a multilateral and multipolar institutional framework. It can also be affirmed that China has become the most dynamic center of the global economy. This has been supported by its growth strategy focused on industrialization, digitalization, innovation, productivity, expansion, and internationalization of its development model—while maintaining a strong emphasis on environmental sustainability. A range of key initiatives and development projects have been implemented to support the country's rise, consolidating its role in the multipolar reconfiguration of the International System. All of this has been essential in driving China’s new phase of development and contributing to the broader process of multipolar transformation. Undoubtedly, China’s rapid ascent represents a significant challenge to the International System, as it reflects a shift in international relations and a transformation in the distribution and hierarchy of global power. Notes [1] It is important to clarify that the so-called Global South should not be equated with the Third World, as the distinction between the First and Third Worlds is primarily based on economic and technological differences, which do not align with the current circumstances of the International System of States. In contrast, the term Global South emerges from a new geopolitical perspective that arose in the post–Cold War context, driven by the need to promote South-South cooperation. Moreover, it does not refer to a geographically defined region, as it includes nations from Latin America, the Caribbean, Africa, and the Asia-Pacific.Revista Política Internacional | Volumen VII Nro. 2 abril-junio de 2025. https://doi.org/10.5281/zenodo.15103898This is an open access article distributed under the terms of the Creative Commons Attribution-NonCommercial 4.0 International License (CC BY-NC 4.0).
