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.

As AI accelerates, the US and China shape the global governance landscape through parallel ambitions and contrasting ideologies. Understanding their policy trajectories reveals key inflection points for potential engagement. The United States and China are the world’s leading powers in artificial intelligence (AI)—and each has global ambitions. As AI development accelerates, so too do calls to regulate it responsibly. Both countries have the capacity to shape the future of AI governance. But understanding where cooperation might be possible requires understanding how each country’s approach has evolved. While their methods and ideologies differ, and their leadership aspirations often appear at odds, two underexamined forces—infrastructure and philosophy—may create unexpected space for mutual engagement. In the US, AI governance has long been shaped by the mythology of the free market. Under President Barack Obama, that mythology was tempered by calls for pipeline diversity. President Donald Trump discarded these in favour of rhetoric about “American values,” an ill-defined phrase deployed more as a competitive cudgel against China than a coherent policy vision. President Joe Biden attempted to resurrect some of Obama’s normative commitments—launching the Blueprint for an AI Bill of Rights, Executive Order 14110 on “safe, secure, and trustworthy AI,” and initiatives like the National AI Research Resource—but the foundations of his administration’s policies remained countering China’s influence through increased export controls and other measures. Trump’s second administration has once again changed focus away from equity and community-centredness, but the continued focus on competing with China and ensuring US “victory” in the “AI race” shows there’s more continuity than often assumed between different administrations’ AI approaches. China, for its part, has been more consistent in its governance strategy, even as it experiments at the margins. Its 2017 New Generation AI Development Plan cast AI as a pillar of national strength, and subsequent regulations on algorithms, deepfakes, generative AI, and facial recognition underscore a clear priority: balancing the “twin miracles” of economic development and social stability. Though early days of “fragmented authoritarianism” have given way to a more centralised approach with specific vertical laws, this logic remains embedded throughout the governance system. China is generally less explicit in its rhetoric than the US, with fewer exhortations about race dynamics and countering the US. In fact, it frequently invokes ideas of ethical pluralism and the language of international cooperation. This framing likely reflects a blend of genuine ideological positioning and diplomatic strategy, but it presents a challenge to US policymakers who continue to frame AI governance in moralising binaries. This is evident in two parallel AI Action Plans released in July 2025. The US released a guiding document—indicatively titled “Winning the Race: America’s AI Action Plan”—with an epigraph from President Trump stating: “As our global competitors race to exploit these technologies, it is a national security imperative for the United States to achieve and maintain unquestioned and unchallenged global technological dominance.” Though the Action Plan itself contains only three substantive references to China, it is built on the premise that global AI is an inherently competitive “race,” and China is clearly the US’s main competitor. A few days after the US AI Action Plan was released, China released its “Global AI Governance Action Plan.” It builds on the 2023 Global AI Governance Initiative, which seeks to portray China as a leader in the global pursuit of AI for the good of humanity and a “champion of the Global South.” The Global AI Governance Action Plan contains fewer specifics than the US AI Action Plan, but calls for “strengthening international cooperation on AI capacity building,” including supporting developing countries to design, implement, and govern AI. It also calls for building a global AI governance system through the UN and again shows the key balance of economic development and social stability: while it acknowledges the need to “jointly push for innovation breakthroughs,” it also advocates for strengthening “policy and regulatory coordination” and building an international AI safety governance framework. The US, on the other hand, is determined to cut “bureaucratic red tape and onerous regulation” while working primarily with its allies. However, recent events have called into question the feasibility of this approach. Notably, despite calls to increase export controls—and mobilise allies to do the same—the US announced shortly before the release of the AI Action Plan that it would again permit Nvidia to export H20 chips to China after previously restricting them. This was part of a trade deal in which China agreed to lighten restrictions on rare earth exports. Though seemingly counterintuitive, this deal reflects a fundamental reality of the modern AI ecosystem: the resources and supply chains enabling it are inextricably intertwined. China mines roughly 70 percent and processes 90 percent of rare earth minerals. US-based Nvidia has 92 percent of the GPU market. Both of these are critical for progress in AI. Both countries are attempting infrastructure decoupling, but the US may have to compromise on its fundamentalism to maintain access to the critical resources it needs. Meanwhile, its advanced chip dominance in turn provides leverage over China. Will this lead to broader cooperation? Geopolitical issues are likely too entrenched for each country to join hands and promote harmonious global AI governance. However, each country’s primary goal is the same: to benefit the “people.” China is claiming that its definition of “the people” is the global community—though this comes with the noted exclusion of domestic critics, including the Uighurs of Xinjiang, who are subject to AI-enabled surveillance and detention. The US’s definition of “the people” has changed from administration to administration, but currently seems to include the American people and potentially allied nations. It’s doubtful that the current administration will agree to substantive global AI governance discussions. But through its Action Plan, China has thrown down the gauntlet—engage with global AI governance or be an obstructionist. What the US will choose remains to be seen. Emmie Hine is a Research Associate at the Yale Digital Ethics Center and a PhD candidate in Law, Science, and Technology at the University of Bologna and KU Leuven.

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).

On March 4, the U.S. Department of Justice charged ten Chinese nationals with carrying out massive hacks against government agencies, media outlets, and dissidents in the United States and around the world. They allegedly acted on behalf of the Chinese company i-Soon, under contract from the Beijing government. Two officials from China’s Ministry of Public Security (MPS) were also indicted, identified as the ones “directing the attacks.” According to documents held by the U.S. justice system, China’s domestic intelligence services (MPS) and foreign intelligence (Ministry of State Security, MSS) relied on a vast network of private companies and domestic contractors to hack and steal information, thereby masking the Chinese government’s direct involvement. In some cases, the MPS and MSS paid private hackers to target specific victims. In many others, the attacks were speculative: hackers identified vulnerable computers, breached them, and extracted information that was later sold — either directly or indirectly — to the Chinese government. The Growth of Chinese Cyberespionage and Its Main Areas of Operation This is not an isolated case. Over the past decade, the People’s Republic of China’s (PRC) hacking program has expanded rapidly. In 2023, then-FBI Director Christopher Wray stated that it was larger than that of all other world powers combined. This increase in power and sophistication has led to success in three key areas: political interference, sabotage of critical infrastructure, and large-scale intellectual property theft. Beijing integrates computer networks, electronic warfare, economic, diplomatic, legal, military, intelligence, psychological, and military deception resources, along with security operations, to weaken states, make them economically dependent on China, and more receptive to a “new authoritarian world order with Chinese characteristics.” For this reason, unlike traditional interpretations, Chinese state-sponsored hacking should be understood within a broader context — where control over technology, strategic infrastructure, and global supply chains is part of “trans-military” and “non-military” warfare operations, as described by two People’s Liberation Army (PLA) colonels in the 1999 book “Unrestricted Warfare”. This approach is known as liminal warfare — an escalating conflict in which the spectrum of competition and confrontation with the West is so wide that the battlefield is, quite literally, everywhere. Cyberespionage as a Tool of Electronic Warfare In electronic warfare, hacking is used for sabotage during times of crisis or conflict. These actions are led by the People’s Liberation Army (PLA), the armed wing of the Chinese Communist Party. In 2023, it was discovered that a hacker group linked to the PLA, known as “Volt Typhoon”, had infiltrated a wide range of critical infrastructure in the U.S. for years, including ports, factories, and water treatment plants — both on the mainland and in strategic locations like Guam. “Volt Typhoon is a military operation with political and potentially military strategic purposes,” explained Ciaran Martin, former director of the UK’s cybersecurity agency. Led by the PLA’s cyber unit, the operation involved installing readiness capabilities — “digital traps,” as some call them — within critical U.S. infrastructure. In addition to a sustained attack in 2023 on a power company in Massachusetts, which aimed to extract sensitive data about its operational technology (OT) infrastructure, “Volt Typhoon” gained notoriety for multiple attacks on telecommunications systems in the U.S. and other critical infrastructures globally. One of its subunits, “Voltzite”, targeted the Littleton Electric and Water Departments, prompting the FBI and cybersecurity firm Dragos to respond jointly and publish a detailed report on the attack and its mitigation. Intellectual Property Theft Through Cyberespionage The most damaging channel for intellectual property theft is cyberespionage. These intrusions allow Chinese companies — sometimes with direct support from the Communist Party or the state — to access information on operations, projects, and technology from foreign firms. China has used state-backed and coordinated cyberespionage campaigns to steal information from companies in strategic sectors such as oil, energy, steel, and aviation. These actions serve both to acquire science and technology and to gather intelligence useful for future attacks on military, government, or technical systems. In the United States, there have been numerous precedents: • In 2014, five PLA hackers were indicted for economic espionage.• In 2017, three hackers linked to the Chinese firm Boyusec were charged with stealing confidential business information.• In 2018, two Chinese nationals were indicted for intellectual property theft.• In 2020, two hackers connected to the MSS were charged with targeting COVID-19 research. Among these, the 2018 indictment stands out as part of a broader U.S. effort to raise awareness about Chinese cyberespionage. On that occasion, Chinese hackers carried out a campaign known as “Cloud Hopper”, which involved a supply chain attack on service providers like Hewlett Packard and IBM. The defendants worked for Huaying Haitai and collaborated with the Tianjin State Security Bureau of the MSS. In 2017, the U.S. Commission on the Theft of American Intellectual Property estimated that such crimes cost the U.S. economy up to $600 billion annually — a figure comparable to the Pentagon’s defense budget and greater than the combined profits of the 50 largest companies in the Fortune 500. Beyond the United States: The Global Impact of Chinese Cyberespionage In June 2024, Dutch military intelligence (MIVD) warned that Chinese cyberespionage was broader than previously believed, affecting Western governments and defense companies. A 2023 cyberattack on the Dutch Ministry of Defense reportedly affected at least 20,000 people within a few months. In 2018, the Czech Republic’s National Cyber and Information Security Agency (NUKIB) issued a warning about risks linked to China. Since then, the country has strengthened its capabilities and controls against Beijing and has worked on mechanisms to counter foreign information manipulation. According to U.S. prosecutors, dozens of European parliamentarians have been targeted by Chinese attacks. In March 2024, the U.S. Department of Justice indicted hackers linked to the MSS for attacking “all EU members” of the Inter-Parliamentary Alliance on China (IPAC), a coalition critical of Beijing. In 2021, the hackers sent over a thousand emails to around 400 accounts linked to IPAC, attempting to spy on their internet activity and devices. In addition, ASML, the Dutch leader in semiconductor lithography, suffers “thousands of security incidents per year,” including several successful infiltration attempts by Chinese actors. Research centers like Imec (Belgium) are also frequent targets. Belgium has expelled Chinese researchers suspected of espionage. The European Union has reinforced security and identified advanced semiconductors as one of four critical technologies requiring risk assessments and enhanced protection. Notably, APT41 is one of the most active and sophisticated Chinese cyberespionage groups, based in the PRC and linked to the MSS. According to Google’s Threat Intelligence Group, APT41 combines state espionage with ransomware attacks — malicious programs that encrypt files and demand financial ransom to restore them — making attribution more difficult. Unlike other PLA-aligned groups whose operations are region-specific, APT41 acts globally, attacking strategic sectors in the U.S., Europe, Latin America, and the Caribbean. It also carries out financially motivated operations, particularly in the gaming industry. Mandiant, a global cybersecurity leader, highlights APT41’s technical capabilities: it frequently exploits zero-day and n-day vulnerabilities and uses techniques like phishing, social engineering, and SQL injections. Since 2020, APT41 has conducted large-scale campaigns against over 75 companies in more than 20 countries. It is responsible for compromising supply chains, such as in the “ShadowHammer” campaign targeting ASUS, which affected over 50,000 systems in 2018. APT41 is also linked to the use of “MESSAGETAP” malware in telecommunications networks. The Role of Chinese Universities in Cyberespionage Chinese universities also collaborate with the PLA and MSS in state-sponsored cyberespionage operations. Shanghai Jiao Tong University works directly with the Chinese military on such operations. Zhejiang University and the Harbin Institute of Technology are key centers for recruiting hackers. Xidian University offers students hands-on experience at provincial MSS offices and previously maintained ties with the Third Department of the PLA’s General Staff before its reorganization in 2015 into the Network Systems Department. One of its graduate programs is co-directed with the Guangdong Office of the Chinese Information Technology Security Evaluation Center (ITSEC), an MSS-run office that leads an active team of contractor hackers. Southeast University also maintains links with security services and co-manages the “Purple Mountain Lab” with the PLA’s Strategic Support Force. There, researchers collaborate on “critical strategic requirements,” operating systems, and interdisciplinary cybersecurity studies. The university also receives funding from the PLA and MSS to develop China’s cyber capabilities. The Cybersecurity undergraduate program at Shanghai Jiao Tong University (SJTU) is taught at a PLA information engineering base. Within this program, SJTU claims to work on “network and information systems testing and evaluation, security testing for connected smart networks, APT attack and defense testing, and key technologies for cyber ranges.” Universities associated with the MSS for talent recruitment include the University of Science and Technology of China, Shanghai Jiao Tong University, Xi’an Jiao Tong University, Beijing Institute of Technology, Nanjing University, and the Harbin Institute of Technology. In addition, some cybersecurity firms — such as Beijing TopSec — collaborate with the PLA in hacking campaigns, operator training, and developing future hackers. This article was originally published by Agenda Digitale and later by Expediente Abierto, who granted us permission for its translation and republication.

In August 2021 the world watched as thousands of people, both Americans and Afghans, crowded onto airplanes at the Kabul airport to escape the return of the Taliban. By the end of August 2021, the United States had evacuated over 200,000 people. On August 15, 2021, Afghan president Ashraf Ghani fled the country, and the Taliban seized control of Kabul calling themselves the Islamic Emirate of Afghanistan. The collapse of the Islamic Republic was predicated on the United States-Taliban deal that was signed in February of 2020. Most people assumed the Taliban would be unable to govern Afghanistan and that their government would not last. After all they were rural tribal people with a fundamental belief in a primitive version of Islam, and their control of Afghanistan from 1996 to 2001 was in many ways a disaster. But, the Taliban have now led the country for four years, with no end in sight. Arguing that they are following basic Islamic law regarding the proper place for women in society, the Taliban have severely restricted the rights of women, restrictions more severe than in any other Islamic country. The treatment of women is the major reason the Taliban has not been recognized as the legitimate government of Afghanistan by many nations (Drury, 2025). The Taliban have also been denied a seat in the United Nations, again largely because of their treatment of women (Lederer, 2025). Recently the International Criminal Court has issued arrest warrants for two Taliban leaders, Haibatullah Akhundzada, the supreme leader of Afghanistan, and Abdul Hakim Haqqani, the chief Justice in the Afghan supreme court, for their treatment of women and girls in Afghanistan (Ayre, 2025). Not only are women not allowed to attend school beyond six grade, but they are not allowed to travel outside of their homes without a male companion. Women traveling outside the home must wear a veil that covers their full body. The Gender Inequality Index, a metric developed by the United Nations Development Program as a composite measure of a women’s place in society, is based on three dimensions: reproductive health, empowerment, and labor market participation. It ranks Afghanistan one of the lowest the world in terms of the treatment of women in government, education, health and political participation (UNDP, Gender Inequality Index, 2025). Gender based violence has also increased. Afghan women experience a high rate of harassment when they leave their homes. Incidents of stoning and verbal harassment have been widely reported. This harassment and abuse is condoned by the Taliban’s Ministry for the Propagation of Virtue and the Prevention of Vice, a Taliban government agency that, among other things, dictates where women can go or not go, what women must wear, and how they must behave. Women who do not follow the rules of this Ministry are chastised, harassed, and often beaten. When women are arrested, they often face verbal abuse and torture (Ahmadi, 2023). Afghan women also often have no say in who they marry and many of these forced marriages are a result of poverty which drives fathers to marry off their daughters, often at a young age (Nariman, 2025). There are very few female doctors or nurses in Afghanistan. Because men are prohibited from treating women, let alone seeing them without their veil, women are often unable to access basic medical services. Maternal mortality rates are high compared to other countries. With poor medical help available for pregnant women, it is estimated that approximately 24 women die each day in Afghanistan due to pregnancy related causes. Most of these deaths are the results of complications during childbirth (Gluck, 2023). Because of the lack of medical support, the infant mortality rate for Afghanistan is 62 deaths per 100,000 live births, one of the highest in the world (CIA, 2024). Afghanistan has always been a poor country with high levels of poverty. Since the Taliban takeover poverty has drastically increased, particularly in the rural areas. It is estimated that over 90 percent of the population of Afghanistan is facing poverty and food insecurity (Programme W. F., 2024). The United Nations Development Project estimates that approximately 85 percent of the Afghan population live on less than one dollar per day (UNDP, 2024). The increase in poverty is in part because donors who had previously supported Afghanistan have halted their support. By 2025, Afghanistan had lost about 26 percent of its gross domestic product as many of these international development projects closed, pushing many Afghans out of work and into poverty (Smith, 2024). With the return of President Trump in 2025, the United States stopped all aid to Afghanistan, worsening the situation. Food scarcity falls most heavily on girls, as poor families make the hard choice of feeding boys before the girls. The mortality rate among girls is 90 percent higher than among boys (Bank, 2023). The increasing level of poverty is exacerbated by the large number of Afghan refugees who are being forcefully repatriated from the countries where they had sought exile, mostly from Pakistan and Iran, but also in some cases from European countries and other countries where they sought refuge. The United Nations High Commission for Refugees estimates that over 96,000 Afghans were forcefully deported back to Afghanistan in April of this year alone, and that over 3.4 million Afghan refugees have been deported from Iran and Pakistan since 2023 (UNHCR, 2025). Most of these returning refugees have no home or job to return to. Although the UNHCR sometimes gives returning refugees a small amount of money as they return, most return to poverty and in many cases without homes. These returning refugees most often settle in areas around major cities, especially Kabul, Kandahar, and Herat, creating a large population of unemployed and impoverished families. The returning refugee problem has been exacerbated by the decision by Iran to expel all Afghans. This is apparently a result of the growing Iranian conflict with Israel (Haqiqatyar, 2025). It is not clear why Iran is expelling Afghans, many of whom had been in Iran for decades. It has been suggested that Iran felt that the Afghan’s were sympathetic to Israel and/or the United States and were acting as spies, although there is no evidence of this. It is estimated that over 6 million Afghans had been living in Iran. The United Nations High Commission of Refugees reports that this year over 1.4 million Afghans have returned from Iran (UNHCR, 2025). Many former Afghan government officials have fled Afghanistan or have been killed as political dissent is not allowed and political parties or ideologies that do not support the Taliban are forbidden. Those who have stayed have largely been quiet. The media is controlled by the Ministry of Information and Culture. This includes the control of newspapers, radio, and television. Most reporters and journalists have fled and female journalists are not allowed (Mercier, 2025). Although there is some opposition to the Taliban government, especially by the National Resistance Front, they have accomplished little and do not pose a serious threat to the Taliban (Bowes, 2024). Other groups such as al-Qaeda and the Islamic State, while present in Afghanistan do not pose a serious threat to the Taliban. These shifts have resulted in a marked drop in fighting, which has brought a form of security to the country. Even though the US travel advisory for Afghanistan remains at ‘level four: do not travel’, in fact tourism, although limited, is beginning. The Taliban government encourages tourism because it brings in much needed foreign currency. The Afghan Ministry of Information and Culture, which oversees tourism, reports that there are at least 350 tourism companies operating in Afghanistan (Lateef, 2025). Humanitarian agencies working in rural areas report that it is now possible to travel into remote areas of Afghanistan, areas that were previously either too dangerous to travel to or too remote. This is in part because the Taliban have embraced the Afghan rural population, and while there still areas that may be dangerous to travel to, much of the anti-government sentiment in the rural area is gone (Smith, 2024). Travel outside of Kabul has also improved as roadblocks have been dismantled, bridges repaired, and roads repaved. While there have been reports of petty corruption at the local level in Afghanistan, corruption under Taliban rule has dramatically reduced. Pre 2021, numerous Afghan government officials, as well as American contractors, made fortunes by funnelling off billions of dollars earmarked for public projects. The corruption took place at all levels so that anything one wanted to do involved a bribe. Corruption was especially found in customs and border checkpoints. It is estimated that during the Republic over 1.4 billion dollars were illegally collected at border checkpoints annually (SIGAR, 2016). Much of this corruption has been eliminated under Taliban rule. Finally, before the Taliban takeover, Afghanistan was the world’s top producer of opium which is used to make Heroin. The Taliban imposed a ban on growing opium in the spring of 2022, with the exception that farmers were allowed to harvest their standing crop. It is estimated that in 2024 about 12,800 hectares of poppies were grown, down from before the ban when farmers planted over 233,000 hectares (Mishra, 2024). However, largely because of economic difficulties, farmers are beginning to grow opium again, even if it is forbidden by the government in Kabul (Mishra, 2024). In sum, despite dire predictions of many the Tailban have managed to stay in power for four years and now seem to exercise firm control of Afghanistan. As explored in this article, they have apparently done some things well and some things poorly – and the international community should expect to see Taliban rule as a fixture in Afghanistan’s near term future. Works CitedAhmadi, B.

A Sobering Anniversary Fifty years of diplomatic relations – and little to celebrate: The 25th EU-China Summit, held in Beijing on July 24, was overshadowed by deep disagreements. From trade disputes to China’s stance on Russia’s war in Ukraine, expectations on both sides were low. While there were symbolic gestures and limited agreements on climate and critical minerals, the meeting highlighted more divergence than convergence. Xi Jinping appeared self-assured; the EU delegation emphasized clarity and unity – but left without substantive concessions. Abstract: The 25th EU-China Summit marked a symbolic milestone – 50 years of diplomatic relations – yet took place in an atmosphere of growing mistrust and confrontation. Geopolitical tensions, an ever-growing trade imbalance, and China’s ongoing support for Russia’s war in Ukraine dominated the agenda. The EU delegation, led by Commission President Ursula von der Leyen and Council President António Costa, sought to recalibrate the relationship and push for concrete outcomes, particularly in trade and global security. Yet Beijing showed little willingness to make concessions. Although both sides agreed on a climate communiqué and a mechanism to address export restrictions on critical raw materials, progress remained limited. China framed the summit as a platform for global cooperation, while the EU left with a renewed sense of caution. Still, the in-person dialogue – the first since 2023 – was seen as diplomatically necessary. For Brussels, the message was clear: without a shift in China’s geopolitical posture, especially towards Russia, meaningful improvement in relations remains elusive. 1. Background The fundamental importance of the relationship was repeatedly emphasized in the run-up to the summit; the EU and China account for nearly 30 percent of global trade in goods and services. Even though there was a slight decline in 2024, bilateral trade still amounted to over 700 billion euros. China is the EU’s second-largest trading partner after the United States.[1] At the same time, discordant tones have increased in recent years: the flooding of the European market with subsidized goods from China, the resulting growing trade imbalance between the two sides, the limitation of market access for European goods, as well as export restrictions on rare earths, are causing dissatisfaction on the European side. While Brussels initially proclaimed at the start of the first von der Leyen Commission that China was—depending on the topic—a partner, competitor, or rival, in recent years the focus has increasingly shifted to competition and rivalry—also due to concerns about excessive dependence on Beijing. The EU’s decision to impose countervailing duties on electric vehicles, in turn, triggered corresponding reactions from China. Politically as well, China’s de facto support for Russia in the war of aggression against Ukraine has significantly changed the EU’s perception of China over the past three years—not to mention concerns about China’s actions toward Taiwan, its support for authoritarian regimes around the world, and its attempts to increasingly shape and shift the discourse in multilateral organizations in its own favor. The statement made in June by Chinese Foreign Minister Wang Yi that China could not afford a Russian defeat, as this would mean that the USA and its Western allies would then turn their attention to Asia[2], reinforced the conviction in Brussels that China supports Russia in the conflict not only in words but also in deeds. Just a few days before the summit, the EU imposed sanctions on Chinese banks for violations of sanctions against Russia, to which China responded with threats of retaliatory measures.[3] In the weeks leading up to the summit, little suggested a resolution to these points of contention. The tougher stance taken by Washington toward both sides in recent months also did not lead to a reduction in dissonance. At the same time, the EU finds itself increasingly under pressure to navigate a balancing act between the strategic interests of the USA and China. China is courting with investments in favor of more “strategic autonomy,” while the USA is pushing for a hard line against Beijing, for example through export controls on critical raw materials. At the G7 summit in Canada, President von der Leyen accused China of using its dominance in raw materials as a weapon against competitors.[4] Beijing rejected the criticism. In Brussels, the fight against climate change is seen as the only somewhat consensual topic, although in the field of green tech—such as electric vehicles or photovoltaics—China is a competitor that challenges the EU. As the controversial vote on tariffs for electric vehicles also showed, EU member states are not always united when it comes to China.[5] Some primarily view China as an important economic partner, others struggle with China’s punitive tariffs, still others see the country as an authoritarian center of gravity that, through support for Russia or through cyberattacks, threatens their own security. Most recently, alongside Hungary—which has been regarded for years as one of Beijing’s closest partners in the EU—the socialist government of Spain also stood out with a charm offensive toward China. The difficulties in the relationship with China have prompted the EU—especially in the new legislative term—to noticeably diversify its economic and political foreign relations: directly before the EU-China summit, closer cooperation was agreed with Japan—also with the goal of reducing strategic dependence on China.[6] 2. Expectations for the Summit On the Chinese side, expectations for the summit were limited from the outset—at least in terms of making their own concessions. In its official communications, Beijing adopted an unusually sharp tone in the lead-up. The spokesperson of the Chinese Ministry of Foreign Affairs, Guo Jiakun, warned the EU not to harm the interests of Chinese companies. Otherwise, China would take measures to protect their rights. At the same time, Guo criticized the new EU sanctions against Russia, which also affect Chinese banks. The normal exchange between Chinese and Russian companies must not be disrupted. Beijing continues to reject the EU’s formula “partner, competitor, systemic rival”—as well as, from the Chinese perspective, unfounded accusations related to the war in Ukraine.[7] This clear defensive posture is also reflected in the public debate. In state-controlled social media, the summit was sometimes mockingly commented on in advance: the Europeans, it was said, would be begging for rare earths on their knees while a strong China benevolently dictated the rules of the game. This self-portrayal reflects a growing sense of self-confidence in Beijing—and at the same time sends a signal: China does not see itself as a supplicant, but as a shaper. Specifically, Beijing hopes for a withdrawal of the new EU import tariffs on Chinese electric vehicles, for which, according to the Chinese side, they are in the final stages of “price negotiations.” From the perspective of European officials, however, the process has been stagnating for months. Further points of friction lie in China’s response to European sanctions—such as the recent imposition of punitive tariffs on French cognac and new restrictions on the procurement of medical equipment. The looming action against European milk and pork exports also fits into this pattern. At the same time, Beijing highlights the fruits of decades of cooperation: bilateral trade has grown from 2.4 billion to nearly 786 billion US dollars over the past 50 years, and mutual investments have reached nearly 260 billion. President Xi Jinping therefore called on the EU to maintain “open cooperation.” “Decoupling” or even “building walls” would only lead to isolation, he warned. China is therefore insisting on further market access in Europe—particularly in key areas such as automobile manufacturing, high-tech, and medical technology—and sees itself increasingly discriminated against by European protective measures. The preliminary reporting on the meeting in state media, however, was predictably conciliatory. The focus was primarily on powerful imagery, portraying China as a responsible actor on the global stage. In a report by the state news agency Xinhua shortly before the summit, it was stated that the meeting offered an opportunity to “consolidate the common interests of China and Europe in a time of global upheaval.” China Daily also struck a cooperative tone on July 24 and warned against endangering the relationship “through protectionist reflexes or foreign policy proxy conflicts.” Europe, the paper said literally, must decide whether it will “continue to make independent strategic decisions—or blindly follow Washington’s course.”[8] What remains unmentioned in China’s narrative is that many of these shared goals currently exist primarily on paper. Accusations regarding competition-distorting subsidies, China’s role in the war in Ukraine, or restrictions on European companies are at best dismissed as misunderstandings. From Beijing’s perspective, the summit appeared to be primarily a diplomatic showcase—rather than a venue for tangible rapprochement. 3. Expectations of the EU Whoever on the EU side may have expected major breakthroughs in light of the anniversary was likely disillusioned by early July at the latest: the reduction of the summit, originally scheduled for two days, to just a single day was an initial dampener; the statements from Chinese ministerial officials and top EU personnel in the weeks leading up to the summit did not suggest that anything fundamental would change regarding the divergences in foreign, economic, and trade policy. The EU is seeking a rebalancing of the relationship. According to Commission President von der Leyen ahead of the summit, the relationship had reached a turning point and now required concrete solutions. Among the EU’s top priorities in the economic sphere are: the rollback of China’s punitive tariffs, measures to reduce the massive trade deficit and counter the redirection of Chinese overcapacities toward the European market, the creation of a level playing field, and export licensing requirements for critical raw materials.[9] In the weeks prior to the summit, there were no signs of Chinese willingness to accommodate any of these demands. Expectations were equally low with regard to geopolitical conflicts, even though the EU’s High Representative had again clearly appealed to China in early July to end its support for Russia. Observers no longer expected a comprehensive joint communiqué ahead of the summit; at most, a joint statement on climate policy with regard to COP30 in Belém, Brazil, was still considered possible. The prevailing opinion: the primary goal was to contain the worsening of relations. Some observers still hoped for minor progress on economic issues. At least there were some diplomatic signals from Beijing in the run-up to the EU-China summit. For example, Mikko Huotari, Director of the German think tank Merics, was allowed to travel to China for the first time in four years. Merics had been subjected to a travel ban in 2021 as part of Chinese counter-sanctions against the EU over its human rights criticism regarding Xinjiang. The lifting of sanctions against individual (former) EU parliamentarians was also interpreted in Brussels as a positive political signal.[10] However, a full lifting of the sanctions is still pending, and travel currently remains possible only under certain conditions—such as by invitation from Chinese institutions, without a guarantee of academic freedom. Observers emphasized that these relaxations were “low-cost” concessions for China. 4. Outcomes of the Summit The low expectations ahead of the summit were at least not disappointed.[11] In their choice of words before and after the summit, both sides made efforts to maintain a respectful tone. Commission President von der Leyen and European Council President Costa did address the well-known critical issues (the need for concrete solutions to recalibrate trade relations, market access for European companies, an end to China’s material support for Russia’s war), but at the same time emphasized the immense importance of the relationship, the shared responsibility for a rules-based international order, and expressed respect for China’s tremendous achievements over the past years and decades.[12] Xi Jinping, on the other hand, did not directly address the divergences between the two sides at all, but instead highlighted the importance of mutual respect, the consolidation of cooperation, an open approach to differences of opinion, and collaboration at the multilateral level. Contrary to some particularly pessimistic forecasts, there were two reasonably concrete outcomes at the summit: First, a supply mechanism for rare earth exports is to be established in order to address supply issues faced by European companies. This would allow companies to contact the EU directly to clarify the causes of delayed exports of critical raw materials.[13] It remains unclear exactly what this mechanism will look like in practice. Second, both sides agreed on a communiqué on climate policy, in which both reaffirmed their cooperation in the climate sector, including on the reduction of greenhouse gases. The communiqué expresses support for the Paris Agreement and the UN Framework Convention on Climate Change. Both sides commit to fair and effective implementation in line with national circumstances. The goal is to advance a just global climate transformation, to support Brazil at COP30, and to improve global access to green technology. By COP30, both sides agreed to present new climate targets for 2035 and to expand cooperation in areas such as the energy transition, methane reduction, and low-carbon technologies.[14] Small steps forward were also made toward closer cooperation in emissions trading, the circular economy, financial regulation, drug control, and geographical indications. A new roadmap for regional policy (2024–2029) was adopted. On the sidelines of the summit, a roundtable was also held with around sixty representatives of European and Chinese companies. In its post-summit remarks, the EU expressed concern about China’s opaque data protection rules and cyberattacks. It also voiced concern about the situation in Xinjiang, Tibet, and Hong Kong, as well as the persecution of human rights defenders. Furthermore, the EU expressed concern about tensions in the Taiwan Strait and the East and South China Seas. It rejected any unilateral violent changes to the status quo and called for peaceful solutions in accordance with international law.[15] 5. Outlook Despite all divergences, the tone in public communication remained at least respectful. However, the summit yielded hardly any tangible progress—particularly in the trade issues central to Brussels. As expected, the EU departed without any concrete commitments. Whether the announced mechanism for rare earth exports will provide substantial added value remains to be seen. From the EU's perspective, the summit confirmed one thing above all: the increasingly skeptical—at times alarmed—view of China remains unchanged. Beijing showed no willingness to make substantial concessions. Instead, the Chinese leadership demonstrated confidence and conveyed the message that it need not act in advance toward a weakened Europe. At the same time, the EU succeeded in clearly articulating key concerns—particularly the expectation that Beijing should use its influence on Moscow to enable progress toward peace negotiations. The clear message: China’s relationship with Russia will play a decisive role in future EU-China relations. One positive aspect from Brussels’ point of view: the appearances of Commission President von der Leyen, Council President Costa, and Estonian Prime Minister Kallas came across as coherent and well-coordinated—an important signal of European unity in difficult times. In addition, according to von der Leyen, the Chinese leadership has begun to address domestic industrial overcapacities under the term “involution.” The latter was regarded as another positive development from a European perspective. Until now, Chinese representatives had consistently denied in talks that the massive overcapacities posed any problem, according to media reports from EU circles.[16] Now, President Xi Jinping and Premier Li Qiang have declared their intent to counteract this trend—against what they perceive as a destructive price war in sectors such as steel, electric mobility, and solar panels. The leadership uses the term “involution” to describe the increasingly intense competition caused by price dumping. Even though some observers hailed the joint climate communiqué as a success, from the EU’s perspective it should be clear: in the field of green tech, China causes massive market distortions through state subsidies and targeted industrial policy—with the goal of creating new global dependencies. Nevertheless, it is undoubtedly important that the summit took place. One must assume that the political system in China—similar to Russia or the Trump administration—functions like an echo chamber; that Xi Jinping likely hears little internal criticism. “That’s why it’s important that the EU leadership tells him directly where the shoe pinches,” emphasized Jörg Wuttke, longtime president of the European Chamber of Commerce.[17] At the same time, it speaks volumes about the state of the relationship when even the mere act of speaking with the EU’s second most important trading partner is regarded as a success of the summit. References[1] https://policy.trade.ec.europa.eu/eu-trade-relationships-country-and-region/countries-and-regions/china_en[2] Exclusive | China tells EU it does not want to see Russia lose its war in Ukraine: sources | South China Morning Post[3] Neue Russland-Sanktionen: China droht EU mit Gegenmaßnahmen | tagesschau.de[4] Präsidentin von der Leyen beim G7-Gipfel[5] https://www.kas.de/en/web/mned-bruessel/global-europe-illustrated/detail/-/content/global-europe-illustrated-eu-member-states-voting-on-tariffs-ev-china[6] AGENCE EUROPE - Faced with economic and security challenges, EU emphasises i...[7] Vgl.

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.

In the Middle East, China seeks to appear neutral by engaging in dialogue with all actors, from Tehran to Tel Aviv, including Riyadh. Beijing's objective is clear: to establish itself as a guarantor of stability to secure its energy and commercial interests. The People's Republic of China's (PRC) commitment to the Middle East reflects a carefully calibrated geostrategic approach, aiming to preserve regional stability, ensure uninterrupted access to energy resources, and promote its famous Belt and Road Initiative (BRI), also known as the 'New Silk Roads.' In this region, the Sino-Iranian relationship is most often highlighted due to its political weight and military dimension; however, whether in economic, diplomatic, or strategic terms, Beijing's presence in this area certainly extends beyond its ties with Tehran. As elsewhere in the world, in the Middle East, China divides its diplomatic partnerships into several types, listed here in descending order of intensity: "global strategic partnerships" (in the Middle East: Egypt, Iran, Saudi Arabia, United Arab Emirates, and Bahrain); "strategic partnerships" (Iraq, Jordan, Kuwait, Oman, Qatar, Syria, Turkey, and the Palestinian Authority); "friendly cooperation partnerships" (Lebanon and Yemen); and finally, "innovative global partnerships" (Israel). China is redefining its priorities in the Middle East  Energy dependence is one of the essential drivers of China's policy in the region. Gulf countries, particularly Saudi Arabia, the United Arab Emirates, and Kuwait, are among the main suppliers of crude oil to the PRC—well ahead of Iran in terms of volume, as well as reliability and investment opportunities. This economic reality compels China to invest much more heavily in the Gulf Cooperation Council (GCC) countries, where financial stability, political predictability, and institutional openness promote sustainable strategic partnerships and infrastructure development, unlike in Iran. For these reasons, the Gulf countries have indirectly become essential nodes in the architecture of the BRI through trade, receiving nearly six times more Chinese investments than Iran. Although Iran has geographical interest as a potential corridor between China and Europe, the persistent effect of international sanctions, poor economic management, and regional adventurism severely limit its ability to attract sustainable Chinese investments. In contrast, Israel offers a functioning and favorable environment for investors, making it a preferred destination for Chinese capital and infrastructure projects. Its economy is based on solid infrastructure and a dynamic technology sector. Despite geopolitical shocks, including the recent clashes with Iran – which will undoubtedly impact the country's business environment – Israel, as a member of the OECD, remains attractive in terms of business environment and investment, mainly because the foundations of its economic environment are stronger than those of Iran or Saudi Arabia. The Hebrew state occupies an increasing place within the BRI – not due to the volume of Chinese direct investments, but because of its strategic position and ambitious infrastructure agenda. Its geographical location – straddling Europe, Asia, and Africa via the Mediterranean – makes it a key land and maritime connectivity point that provides an alternative option to Iran for linking China to Europe. In this context, China and Israel have made progress in their negotiations for a free trade agreement that has been discussed since 2016. Although discussions have been suspended since 2023, there remains hope that an agreement could be signed once stability returns to the region. China's trade with Israel and Iran: divergent trajectories China's commercial relations with Israel and Iran reveal two distinct economic approaches.  With Israel, trade is increasingly marked by imports of high technologies - particularly in the semiconductor field - reflecting a growing technological interdependence.  In contrast, trade with Iran remains focused on industrial goods and natural resources, illustrating a more traditional partnership based on access to raw materials. These contrasting dynamics reflect China's strategic flexibility, which relies on Israeli innovation while securing its supplies from Iran.  Tensions in the Strait of Hormuz are testing China's strategy in Iran  For nearly fifty years, Iran has turned to China for economic support. However, despite 21 Chinese greenfield investment projects between 2003 and 2020 – mainly in the energy sector – Beijing has gradually begun to disengage due to international sanctions and ongoing regional instability. Large companies such as CNPC and Sinopec have reduced their stake, or even abandoned some projects, while tech companies like Huawei and Lenovo have also scaled back their presence in the Iranian market. Between 2017 and 2019, Iran reportedly saw an outflow of Chinese capital estimated at $990 million. China views instability in the Middle East, particularly the confrontation between Israel and Iran, as a direct threat to its economic and commercial interests. As the world's largest buyer of Iranian oil, China is especially concerned about potential disruptions in strategic maritime routes, particularly the Strait of Hormuz. In June 2025, Chinese oil imports from Iran significantly increased, reaching up to 1.8 million barrels per day – a surge that occurred just before the military escalation between Israel and Iran, which raised concerns about the security of the Strait of Hormuz. A sign of the weight of the PRC in this region: after the reciprocal airstrikes between Israel and Iran, and Tehran's threat to close this crucial passage, U.S. Secretary of State Marco Rubio urged Beijing to intervene, emphasizing China's heavy dependence on this oil route. China–United States: strategic tensions in a transitioning Middle East China and the United States recently signed a trade agreement and established a 90-day tariff truce, aiming to resolve some key disputes and stabilize economic relations. Furthermore, on the military front, Iran and China signed a military cooperation agreement as early as 2016, reflecting their mutual desire to counter American influence in the region and secure trade routes. Historically, China has supported Iran through arms sales, technology transfers, and training programs. Moreover, despite the official rhetoric, some reports suggest that Chinese technologies have contributed to the development of Iran's ballistic program. The Sino-Iranian relationship in defense illustrates a two-level diplomacy: China discreetly supports Iran's military autonomy while ensuring it does not compromise its strategic relationships with other important regional partners, including Israel, with whom it also maintains top-level security dialogues. This highlights Beijing's broader ambition: to avoid regional polarizations and maintain a balance of power favorable to its interests. China's strategy in the Middle East towards the United States is based on a principle of equidistance: to increase its influence without direct confrontation, while drawing strategic benefits from Saudi Arabia, Israel, Iran, and Egypt. In this perspective, the People's Republic of China does not seek to replace the United States as the dominant power in the region, but rather to offer a multipolar presence focused on preserving stability. Maintaining the status quo, avoiding direct conflicts, and building a parallel system of influence through infrastructure, trade, and diplomacy are the pillars of China's position in the Middle East. This approach ensures Beijing secure access to energy, trade corridors, and sustainable geopolitical influence from Tel Aviv to Tehran.

Abstract European states currently lack a clear joint strategy on China and a coordinated approach to US–China competition. This article offers a novel perspective on the challenges for European approaches to this issue due to an omnipresent transatlantic component and the risk of an alliance dilemma. Illustratively focusing on France, Germany and the UK, it demonstrates that Europeans are facing a transatlantic alliance dilemma with the risks of abandonment and entrapment. It argues that Europe needs to strike a balance between its dependence on Washington, especially with regard to European security, while fearing entrapment by the US approach towards Beijing as it aims to maintain economic ties with China. The article concludes that the ramifications of this dilemma can be mitigated through a distinctly European approach to China, strengthening European coordination on China and bolstering European strategic autonomy. As a conceptual piece rather than a full empirical analysis, this article therefore unpacks the strategic challenge and lays the groundwork for further empirical works on the topic. Introduction Strategic competition between the US and China plays out in many realms of international affairs, ranging from global trade to security in the Indo-Pacific. European states are directly affected by this dynamic as they maintain critical ties with both sides. Albeit allies of the US through NATO, Europeans have been reluctant to align with the US on its approach to the Indo-Pacific and China, which is currently characterised by the quest to win the strategic competition with Beijing in all areas of international affairs (see Leoni 2023). Furthermore, Europe maintains close economic ties with Beijing, and imports from China to the EU have most recently increased (Lovely and Yan 2024). European governments certainly do not pursue an approach of maintaining equidistance between the US and China: not only do they regularly emphasise their strategic proximity to Washington, but more recent events, such as the willingness of European allies to publicly adopt the wording of the communiqué from NATO’s Washington summit (NATO 2024) describing China as an ‘enabler of Russia’s war effort in Ukraine’, clearly demonstrate that the tone is changing in European capitals (Politi 2023). However, Europeans still tend to emphasise China’s role in global affairs and the importance of including it in multilateral cooperation formats. With the re-election of Donald Trump as US president, European policy on China and its approach to US–China competition will increasingly be a focus of the US administration. While the exact approach of the new US government still remains to be defined, there are good reasons to anticipate a more hawkish China policy from Washington, through which the US might seek not only to further compete with China, but to actually win this competition (see Pottinger and Gallagher 2023). When designing their approaches towards China—which, among the key European states, only Germany has done so far, with the publication of its China strategy in 2023—Europeans always face a transatlantic elephant in the room. US–China competition, a structuring feature of international relations shaping the global order today through the increasing emergence of geopolitical blocs (see Leoni and Tzinieris 2024), and China’s rising global influence in almost all areas of international affairs—ranging from climate to economics, the rules-based order and security—are forcing European states to reflect on their approach vis-à-vis Beijing (for a full discussion, see Oertel 2023; García-Herrero and Vasselier 2024). As NATO members, European states also need to adapt their strategy in light of the partnership with the US as their key ally. This article argues that European approaches towards China, as shown in the examples of France, Germany and the UK, have a distinctly transatlantic component. It illustrates how these three European states find themselves in an alliance dilemma with the US, and how the risks associated with alliances also define European approaches to China and US–China competition more broadly. As the US administration regularly refers to China as a ‘challenge’ (US Department of Defense 2022), this article alludes to this formulation through the coining of the term ‘transatlantic China challenge’ to describe the strategic challenges Europeans are facing with regard to defining their approach vis-à-vis China and US–China competition more broadly. It offers a conceptual understanding of the strategic challenges for Europe in this context and thereby constitutes a basis for a more thorough empirical analysis. The alliance dilemma and European strategy in US–China competition Originating in realist international relations theory, the alliance dilemma generally describes a situation in which states face risks resulting from joining an alliance. As demonstrated by Snyder (1984), smaller allies especially face a parallel risk of abandonment and entrapment by a hegemon, that is, the dominating power, after joining an alliance. Abandonment, in these circumstances, implies that the hegemon has no further interest in defending or supporting the smaller allies, whereas entrapment refers to a situation in which a state is ‘dragged into a conflict over an ally’s interests that [it] does not share, or shares only partially’ (see Snyder 1984, 466–8). In the context of alliances, a small state is ‘the weaker part in an asymmetric relationship, which is unable to change the nature or functioning of the relationship on its own’ (Wivel et al. 2014, 9), and hence has more limited space for action than the great powers (Wivel and Thorhallsson 2018, 267). This definition arguably applies to Europe in its partnership with the US, as demonstrated by the excessive military and economic dominance of the US as compared to the European states (see Stockholm International Peace Research Institute n.d.; International Monetary Fund 2025). The re-election of Trump as US president now presents the risk of an increased alliance dilemma for Europeans. On the one hand, Trump has announced several times that he does not value the alliance commitments within NATO and potentially would not defend European allies (Sullivan 2024), threatening Europe with abandonment. This scenario is being taken seriously in European capitals, and reflections on how ‘defending Europe with less America’ (Grand 2024) could shape up have gained traction, especially in 2024. Similarly, defence initiatives within the EU to enhance the European contribution to the continent’s security have leapt forward in recent years (see Scazzieri 2025). On the other hand, even the Biden administration had pushed Europe to align with the US approach on China (see Lynch et al. 2023). However, France and Germany in particular, as the big EU member states, have been hesitant to do so, as reflected in France’s opposition to the opening of a NATO liaison office in Tokyo (McCurry 2023) and Germany’s vote against tariffs on Chinese electric vehicles, fearing reprisals from Beijing (Demarais 2024). Trump’s foreign policy might be strongly characterised by issue linkage, which means that policies in one area will be linked to those in another area. Through this strategy, the new US administration might force Europeans into alignment and thereby entrap them, making them accept policies they are not eager to support (see Barkin and Kratz 2025). The exact policies of the Trump administration vis-à-vis European allies remain to be seen, but it is not hard to imagine a scenario in which abandonment and entrapment could emerge or increase, namely when the threat of abandonment is used to entrap allies and force them to support certain policy decisions. The alliance dilemma could play out for Europeans specifically when designing their approaches towards China (see Barkin and Kratz 2025) and formulating their response to US–China competition more generally. As noted above, among the big European states, only Germany has formally adopted a strategy on China, in 2023 (The Federal Government of Germany 2023). However, China and the response to US–China competition takes a prominent place in France’s Indo-Pacific Strategy and its strategy review (Government of France 2021; Secrétariat général de la défense et de la sécurité nationale 2022), and the UK systematically included the dimension of strategic competition in its Integrated Review and its refresh (Government of the United Kingdom 2021, 2023) and has announced an ‘audit’ of its China policy under the new government (Taylor 2024). While these strategies emphasise their individual approaches towards China and the risks stemming from US–China competition, the US has increasingly pressured Europe to align with its approach (Lynch et al. 2023) and can be expected to continue this pressure (Barkin and Kratz 2025). Through the potential issue linkage of security (openly questioned by President Trump) and China policy, Europe therefore finds itself in a new form of alliance security dilemma. European approaches to US–China competition: strategic hedging How can Europe respond to the alliance dilemma of the risks of abandonment and entrapment when it comes to its approaches to China? Reviewing the theoretical literature on the alliance dilemma, one can imagine different strategies. According to Snyder, members of alliances can choose between strategies that strengthen or weaken their commitment to the alliance. To demonstrate commitment, actions could include reassurances for the ally or demonstrations of loyalty, whereas actions to weaken the commitment to the alliance could consist of restraining the ally (mostly to reduce the risk of entrapment in a conflict), increasing bargaining power over the ally or preserving options for realignment outside the existing alliance (for a full discussion, see Snyder 1984, 466–9). Alternative strategies include hiding from cooperation, that is, ‘seeking to maximize autonomy by opting out of specific aspects of the cooperation or by setting up “bastions” in the cooperation’, or bandwagoning, through which states pursue strategies of adaptation ‘to the more powerful actors in the cooperation’ (Pedersen 2023, 442). At the moment, it seems that France, Germany and the UK ‘drive on sight’ rather than approaching the question holistically. The following analysis aims to unpack how the three European states see US–China competition, the risk of the alliance dilemma and how these reflections have played out so far in their strategies. The strategies of France, Germany and the UK on China demonstrate that their approaches are influenced by a distinctly transatlantic component and reflect the transatlantic alliance dilemma. This is visible in their (1) high awareness of the risks stemming from great power competition, (2) approaches to managing the risk of short-term abandonment, and (3) hedging to mitigate the medium- and long-term risks of abandonment and entrapment. The empirical evidence for this analysis was gathered through a qualitative analysis of European strategic documents, statements and policy decisions taken mostly during the period of the Biden administration. However, in light of the risk of a scaling-up of the alliance dilemma under the Trump administration, sources and evidence accessible by the end of January 2025 were included to illustrate the European approaches. In addition to publicly available documents and the sources mentioned above, this paper draws on conversations with policymakers and experts under the Chatham House rule. Mitigating risks from US–China competition: multilateralism instead of alignment That France, Germany and the UK are close allies with the US is clearly visible in their respective strategies on China, not least because of references they make to the importance of the alliance and their descriptions of their own positions between the two great powers. Overall, France, Germany and the UK share the perception of US–China competition and the emergence of blocs as potentially harmful to their interests. As a consequence, all three call for an inclusive multilateral order instead of falling into a logic of blocs, as the increasing competition is seen as a risk for Europe (Secrétariat général de la défense et de la sécurité nationale 2022, 9–15; The Federal Government of Germany 2020, 24–6; Government of the United Kingdom 2023, 22–6). The response of all three European powers to the emergence of blocs is multilateralism: instead of clearly aligning with the US, the French, German and British strategies call for building broader multilateral coalitions, which should, eventually, also include China (The Federal Government of Germany 2020, 23–6; Government of the United Kingdom 2023). The tone in Paris, Berlin and London towards Beijing has clearly changed over recent years; accordingly, the European capitals were also willing to support strong wording on China in the 2024 NATO summit declaration, which describes China as a ‘critical enabler’ of Russia’s ongoing war against Ukraine (NATO 2024). Albeit also recognised as a critical partner for key issues such as climate policy and trade, European states openly describe China as a ‘systemic rival’ and occasionally call out China’s behaviour, as they did, for example, in the case of a note verbale on the South China Sea (UN 2020). Nevertheless, Europe has not (yet) given in to US pressure to align with Washington’s more confrontational approach towards China (Etienne 2024). Even if European states and Washington have moved closer to each other, especially on economic security (Meyers and Reinsch 2023), the European positions on US–China competition demonstrate that Europeans are not willing to fully endorse or follow Washington’s approach—not least because European imports from China have increased in recent years (Lovely and Yan 2024). Managing the risk of short-term abandonment Since Trump’s election, the risk of abandonment by the US has been seen as increasingly high in Paris, Berlin and London.1 This is not least because Trump has openly questioned his willingness to adhere to Article 5 of the North Atlantic Treaty in the case of an armed attack on Europeans (Sullivan 2024). Europeans are especially concerned about issue linkage in this context, meaning that demands in a policy area other than security could be used as a condition. Concretely, Trump could use the threat of abandonment as leverage to compel Europe to align with the US on China policy.2 Barkin and Kratz (2025) suggest that Europe adopt a ‘carrot and stick’ approach, whereby Europe could start with an offer to the US: buying more liquified natural gas, defence goods and agricultural products from the US could mitigate the risk of abandonment. However, there is awareness among European states that coercion from the US to align on US–China policy, especially when linked to the threat of abandonment, might best be mitigated through enhancing European military capabilities—which would still leave the continent exposed to these threats, though to a lesser extent.3 Addressing the risk of medium- and long-term abandonment and entrapment: transatlantic hedging However, the risk of at least partial abandonment is not a new challenge for European strategy, and had already infused earlier strategic thinking. The shift of US strategic priorities away from Europe and to the Indo-Pacific has already been demonstrated in the allocation of resources to the different theatres. Moreover, European states have increasingly become aware that US forces will be withdrawn from their territories in the future and have concluded that they will have to step up their own commitment to European security (see Grand 2024). In parallel, there is an awareness in European capitals that showing more interest in the Indo-Pacific and giving more importance to policy on China is also a way for Europeans to demonstrate an understanding of their ally’s strategic priorities.4 Accordingly, the approaches of France, Germany and the UK to China and the Indo-Pacific also have to be understood as a commitment to the priorities of the US in order to keep this ally engaged in the European theatre and mitigate the risk of abandonment; however, European states abstain from fully aligning with the US approach, as their capabilities and strategic goals are perceived as diverging from those of the US. In this way, Europe aims to avoid entrapment over the medium term through slightly distancing itself from US policy. While all three European states also call for de-risking from China and diversification of their supply chains, maintaining strong economic ties with Beijing is a key component of their respective approaches—which contrasts with the US calls for decoupling. Furthermore, these states have never formally endorsed the US policy on China (Etienne 2024). Nevertheless, enhancing European capabilities would not only send a signal to Washington, but also qualify as hedging, understood as an ‘insurance policy’ to avoid a deterioration in US–Europe relations if the US opted for abandonment, or even as part of a move towards emancipation to reduce strategic dependencies on Washington (see Fiott 2018, 4–6). Conclusion: a transatlantic China challenge Designing their approaches to China and to US–China competition more broadly constitutes a complex strategic dilemma for European states. Paris, Berlin and London do not fully align with Washington’s approach, and it remains to be seen whether they will be willing to do so under the second Trump administration. To manage the risk of abandonment and entrapment, European states pursue different individual approaches to strategic hedging: their strategies on China and US–China competition are designed in a way that allows them to mitigate the risk of abandonment which might stem from significant transatlantic divergence, and to avoid automatic entrapment through their slight distancing from the US approach. From a theoretical perspective, this article has demonstrated that the alliance dilemma, along with the parallel fear of abandonment and entrapment by the US, is a major factor accounting for Europe’s limited strategies on China and its hedging behaviour. This article offers a conceptual analysis of the structural forces explaining European strategies, but other strategic cultures and relationships with the US could offer important complementary insights. To further analyse how individual European states design their strategies vis-à-vis China in light of the alliance dilemma and potential domestic constraints and specificities, neoclassical realism could offer an interesting analytical concept. This approach posits that structural forces set the parameters for foreign policy and treats domestic factors, including strategic culture, as intervening variables (see Rose 1998). Accordingly, it appears well suited for foreign policy analysis, and has indeed gained popularity in the field in recent years (see, for example, Martill and Sus 2024; Meibauer et al. 2021; Weber 2024). Empirically, this article constitutes a conceptual starting point rather than an exhaustive analysis of the strategy-making processes of European states with regard to China and US–China competition and makes a more comprehensive assessment desirable. The findings of this article have broader implications for policymaking. First, they demonstrate the necessity for Europe to determine its place in the increasing US–China competition. European coordination on the respective approaches vis-à-vis the US—especially in light of potential coercion to align—and China is of paramount importance to ensure that foreign policy strategies are mutually reinforcing and not undermining European objectives. Second, the article demonstrates that Europe currently responds to the ‘transatlantic China challenge’ through transatlantic hedging: while this strategy seems to be promising in the short term, it is questionable to what extent the strategy is sustainable and could help European states to navigate the parallel challenges of abandonment and entrapment. Unless Europe decides to fully align with the US—and it is questionable whether this decision would be in its interest—European states would be well advised to develop a sustainable long-term approach to China. A transatlantic dialogue on China, in which Europe and the US openly discuss synergies and divergences, could help prevent misunderstandings and decrease the risk of coercion or issue linkage due to a misreading of European approaches in Washington. Third, as the risks of (at least partial) abandonment and entrapment are systemic challenges due to the current composition of the transatlantic alliance, a logical step for European states to decrease their dependence on the US as the hegemon in the alliance would be to significantly strengthen European capabilities. Stronger military capabilities could help mitigate the ramifications of abandonment, and the aforementioned distinctly European strategy could allow Europe to avoid strategic entrapment in relation to China imposed by Washington. As Europe remains the junior partner in the transatlantic alliance, the parallel risks of abandonment and entrapment, as well as issue linkage, are highly likely to influence its approaches towards China in the long term, but there are certainly ways to render this ‘transatlantic China challenge’ less challenging. ORCID iDGesine Weber https://orcid.org/0009-0008-2643-0400Footnotes1.

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.
