Provider of in-depth & balanced analysis on hot issues around the world

Introduction Technological innovation is accelerating at an unprecedented pace, reshaping how societies generate energy, transport people and goods, produce food, fight disease, and explore space. Across multiple sectors, groundbreaking solutions are emerging in response to global challenges such as climate change, public health threats, energy insecurity, and resource scarcity. This article examines seven transformative technologies — from wireless electric-vehicle charging roads and regenerative ocean farming to graphene applications and disease-eliminating robots — each demonstrating how science and engineering are redefining sustainability, resilience, and human capability in the 21st century. 1. Wireless Electric Vehicles Charging Roads Electric Vehicles (EVs) have become key technology to decarbonise road transport, a sector that accounts for over 15% of global energy-related emissions. The increase of their sales globally exceeded 17 million in 2024, and it is forecasted to surpass the 20 million units by 2025. (IEA, 2025) Source: IEA analysis based on country submissions and data from the European Automobile Manufacturers Association (ACEA), European Alternative Fuels Observatory (EAFO), EV Volumes and Marklines. Despite this growth, several concerns continue to slow down their widespread adoption. Limited charging infrastructure, battery-related autonomy issues, high purchase costs, slow charging times, and the environmental impact of the battery productions remain major obstacle. The broader EV industry, however, is actively developing new technologies to overcome these challenges. (Automotive Technology, 2025) In this context, one of the most pressing challenges is energy supply – specifically, the need for better batteries and more accessible charging points. To address this bottleneck, a promising new trend has emerged: wireless roads capable of charging EVs while they drive. This technology could fundamentally transform the charging experience and significantly reduce dependence on stationary chargers. The idea is simple, a system that supplies power to EVs while driving, using embedded inductive coils (wireless charging) or conductive rails on the road, in other words a dynamic or in-motion charging on the road. In fact, this technology already exists and there are several examples worth mentioning: - South Korea: introduced in 2013, the first road-powered electric vehicle network, in which electrical cables were buried below the surface and wirelessly transfer energy to the electric vehicles via magnetic resonance. An electrified road has the advantage of eliminating the plug-in infrastructure and vehicles usually require a smaller battery, reducing weight and energy consumption. In 2009, KAIST introduced the OLEV (online electric vehicle), a type of EV that uses wireless dynamic charging through inductive coils embedded in the road. The OLEV public transport buses were later used in the 2013 first electric road in the city of Gumi, which consisted of a network of 24 km, by 2015 the number of OLEV buses increased to 12 (Anthony, 2013) and another bus line was launched in Sejong that same year. (SKinno News, 2021)- Sweden: a 1.6 km road linking Stockholm Arlanda airport to a logistic site outside the capital city was a pilot project achieved in 2016. (The Guardian, 2018), (Carbonaro, 2022) However, the Swedish government didn’t stop there and by 2020 they built a wireless road for heavy trucks and buses in the island city of Visby, and they are planning to expand it to the 13-mile E20 highway – logistic hub between Hallsberg and Örebro – and even have a plan of further 3,000 km of electric roads in Sweden by 2035. (Min, 2023), (Dow, 203)- USA: a quarter mile (400 m) section of road through the Corktown area of Detroit was changed to a wireless electric road. Electreon was the company in charge of the project. (Paris, 2024), (6abc Philadelphia, 2025)- France, Norway and China: Electreon – a leading provider of wireless charging solutions for EVs – has partnered and gained projects for wireless highways in France – a section of the A10 highway (Electric Vehicle Charging & Infrastructure, 2023) –, Norway – evaluation of wireless charging for AtB’s BRT routes in Trøndelag (Foster, Electreon to install the first wireless electric road in Norway, 2023) – and China – not wireless but in an 1.8 km electrified highway in Zhuzhou. (Foster, China demonstrates electrified highway, 2023) While all these examples show a “tendency” to switch into wireless roads, it is important to highlight three points to keep that are decisive and have slowed down the transition: in first place, these wireless roads are being targeted mainly for freight trucks and buses, the second point is the initial cost of the infrastructure is high and third point is the technology that should be added to the EVs. 2. Fire Suppression Using Sound Waves Seth Robertson and Viet Tran, engineering students from George Mason University in Virginia designed a fire extinguisher that uses sound waves to put out flames. Their device emits low-frequency sound waves that disrupt the conditions necessary for a fire to sustain itself, meaning that no foam, powder, chemicals or water are needed to extinguish a fire, just sound. In order to understand how it can be possible to extinguish fire with sound it is necessary to remember that a fire needs heat, fuel and oxygen to survive, if one of these elements does not appears, there is no fire, under this principle, Robertson and Tran’s prototype uses sounds to separate the oxygen from the flame, as a result, the fire extinguish. The interesting part is that the sound must have the right frequency, specifically between 30 to 60 Hz – low frequency sounds. The sound waves will act as pressure waves moving the air molecules back and forth, and in the right frequency, the movement will disrupt the flames’ structure, separating the oxygen molecules and the fire will simply die out with the lack of these molecules. Potential applications include small kitchen fires or small fires, while unfortunately, large-scale structural or wildland fires still remain a challenge, mostly due to the environmental factors, like wind, air density and flame intensity, that can be a hurdle in uncontrolled environments. Moreover, the generation of low-frequency sound waves powerful enough to suppress fires requires a significant amount of energy. Nonetheless, an early prototype consists of an amplifier to generate low-frequency sound and a collimator to focus the sound waves directly on the fire, and as mentioned before, one limitation is that specialized equipment is required to produce the high-pressure sound waves. Still, research has been carried out recently and it is expected that this technology could be a non-destructive and less damaging method for firefighters soon. https://www.youtube.com/watch?v=uPVQMZ4ikvM 3. Regenerative Ocean Farming Regenerative ocean farming is a climate-friendly model of aquaculture where seaweed and/or shellfish are grown in a way that requires no freshwater, feed or fertilizer, as the crops naturally filter nutrients from the water and capture carbon and nitrogen. This farming model can benefit coastal ecosystems and communities by increasing food security, creating jobs, improving water quality, protecting coastlines, supporting ocean justice (Urban Ocean Lab, 2023) and most importantly, mitigating climate change. Ocean farming can rely on a polyculture system – cultivate a mix of shellfish and seaweeds – or just a single species system. While the climate conditions determine the species to grow, it does not affect the system itself. The system follows a vertical layer farming way, in which farms use ropes that extend vertically from the surface to the seabed, in addition to the use of different levels and cages for scallops, oysters or clams, for example, as shown in Figure 2. Other species like kelp, abalone, purple sea urchins or sea cucumbers can also be harvested. Figure 2: Ocean farming diagram. Source: Urban Ocean Lab The big advantage is the maximization of the ocean space, producing more food in a smaller footprint, in addition to the use of the benefits of the species – seaweed and shellfishes – which are both natural filters that help to clean the water and absorb excess nutrients, combating ocean acidification and reducing marine pollution (Hassan, 2024) naturally. Moreover, the versatility of these species allows them to use them in other areas, such as biofuels, soil fertilizers, animal feed or cosmetics and not only for human food. Around the world, there are several projects that have adopted this methodology (Hassan, 2024): 1. GreenWave (USA): increased biodiversity by 50%, reduced nitrogen level in water by 20% and created sustainable job opportunities for locals.2. Ocean’s Halo (Ireland): annual harvest of 500 tons of kelp, creation of 20 jobs in rural areas and carbon footprint reduction by 30%3. Kitasaku Marine (Japan): Nori production increased by 25%, coastal water quality improved by 15% and local support of 50 locals.4. Catalina Sea Ranch (USA): harvested 1 million pounds of mussels annually, increased local biodiversity by 20% and created 10 new jobs.5. Blue Ventures (Madagascar): harvested 146 tonnes of red seaweed, plus they have created a sea cucumber market with a value of $18,000 and 700 farmers have been trained to farm in the ocean. (Blue Ventures Conservation, 2015)6. Havhøst (Ocean Harvest) (Denmark): they are growing seaweed, mussels and the European flat oyster in 30 communities along the Danish coast. In addition, they focus on educational activities to introduce ocean farming to more people. (Waycott, 2022) Overall ocean farming creates a positive environmental impact; it provides a sustainable food source and economic opportunities for the local people and the industry. Of course it faces challenges, but it has become a way to mitigate climate change and protect the ocean. 4. Wave Energy Generators There are two types of waves. Surface waves are generated by a combination of wind passing over the sea’s surface raising up water and gravity pulling it back down. In a technical way, warm air rises and expands, creating areas of low pressure compared to places with cooler air. Air then moves from high-pressure areas to low-pressure areas. This movement of air is wind and when it rushes across the surface of the Earth it creates waves in oceans. (Lumley, 2025) On the other hand, underwater waves are sound waves produced by earthquakes or volcanic eruptions; these waves travel by compressing and expanding the water. (Kadri, 2025) In both cases temperature variations and other factors can affect the nature of the waves. For instance, wave energy or wave power harnesses the ocean’s waves to generate energy by converting a wave’s kinetic energy into electricity. Wave power is a form of renewable and sustainable energy which has potential cost benefits over solar and wind but faces technological challenges limiting its large-scale adoption in electricity generation and water desalination. (Lumley, 2025) The nature of the waves makes wave energy the world’s largest source of energy with a potential of annual global production of 29,500 TWh, according to the Intergovernmental Panel on Climate Change (IPCC, 2012). In addition, it works well in tandem with other renewables such as wind. (Ocean Energy Europe, s.f.) In terms of technology itself, wave energy has relied on the next devices: 1. Point absorbers: floating buoys that capture the vertical movement of waves, which then is harnessed through a cable anchored to the seabed. The vertical movement of the waves is subsequently transformed into electricity via converters (alternators, generators or hydraulic systems). These are usually mounted on the seabed in shallower water and are connected to the floating buoys.2. Oscillating water columns (OWCs): a partially submerged, hollow structure connected to an air turbine through a chamber. These devices use the rise and fall of the waves to compress air, the air is forced to move back and forth in the chamber and creates a strong air flow that powers the turbine, generating electricity.3. Overtopping devices: a floating structure made of segments linked together, which lifts up and down with the waves. These devices harness wave energy by allowing waves to flow into a reservoir, which then releases the water through turbines to generate electricity. Design, flow dimensions, turbine efficiency and structural elements influence their efficiency. Source: BKV Energy Despite its huge potential and considering it as a clean energy source with no GHG emissions, the main concern related to wave energy is the marine life affectation – including habitat alteration, noise pollution or collision risks for marine life. On the other hand, high costs, complex design, maintenance and technological constraints also have become a problem, still, the potential of this continuous energy is huge compared to the more limited wind energy, for example. (Lumley, 2025) Despite all that, there are some active projects being developed in different parts of the world, for example: Azura Wave Power (tested in Hawaii), Anaconda WEC (UK’s prototype), CalWave (in California), CETO (tested in Australia and expected to be tested in Spain too), Crestwing (tested in Denmark), HiWave-5 (Swedish-based tested in Portugal), the Wave Energy Program (in India) or the Ocean Grazer WEC (developed in The Netherlands), among many others. (Wikipedia, 2019) 5. SpinLaunch SpinLaunch is a spaceflight technology development company working on mass accelerator technology to move payloads to space. This innovative space company is known for their Meridian Space and their Suborbital Accelerator. The Meridian Space is a low-cost, highly differentiated LEO satellite communications constellation which offers speed, reliability and flexibility (SpinLaunch, 2025). The company has partnered, and investments have been achieved in order to launch 280 satellites (Berger, 2025) as part of their satellite constellation, which will satisfy the needs in any area needed such as maritime, national security, communications, corporate networks, aviation, military, etc. The highlight of these satellites is their mass that is only 70 kg, and its facility to be launched in one or two rockets. On the other hand, SpinLaunch is aiming to build a kinetic launch system that uses centrifugal force instead of traditional rockets and spins a rocket around at speeds up to 4700 mph (7,500 km/h) before sending it upward toward space. At 60 km or so altitude, the rocket would ignite its engines to achieve orbital velocity. To achieve this, they have built a Suborbital Accelerator prototype, in Spaceport America, New Mexico. This prototype is a 33-meter vacuum chamber that can launch payloads from 800 to 5000 mph. Several tests have already been carried out, being the 10th the latest on September 27th, 2025. (Young, 2025) SpinLaunch hopes to have a 100-meter Orbital Lauch system by 2026. The engineering behind these systems is as follows: both systems are circular accelerators, powered by an electric drive that uses a mechanical arm to sling payloads around in circles to reach incredibly high speeds of up to 5,000 mph. They then release the payload through a launch tube and spaceward. (Young, 2025) The company claims that their method is cheaper as it eliminates 70% of the fuel compared to the traditional rocket launch, in addition, the infrastructure is less, and it is more environmentally friendly than the traditional methods. However, the limitations are seen in the payload weight (no more than 400 kg per payload) and their resistance (payloads must be able to withstand up to 10,000 G’s of force during the centrifugal acceleration process) Source: SpinLaunch. 6. Disease-Eliminating Robots “Disease-eliminating robots” encompass a diverse set of robotic and AI-driven systems designed to prevent, monitor, and treat infectious diseases while minimizing human exposure to risk. These technologies operate at multiple scales — from environmental disinfection in hospitals to microscopic interventions inside the human body. Environmental disinfection robots are among the most established applications. Devices such as Xenex and UVD Robots utilize pulsed ultraviolet (UV-C) light to destroy viral and bacterial DNA, effectively sterilizing hospital rooms within minutes (UVD Robots, 2023; Xenex, 2024). Others deploy vaporized hydrogen peroxide (VHP) to disinfect enclosed environments like train carriages and operating rooms (WHO, 2022). These systems substantially reduce hospital-acquired infections (HAIs) and cross-contamination risks. In medical and clinical settings, robotics contribute to precision and safety. Surgical robots such as Intuitive Surgical’s da Vinci and Ion platforms enable minimally invasive operations with reduced infection risk and faster recovery times (Intuitive Surgical, 2024). At the microscopic level, nanorobots are under development for targeted drug delivery, capable of navigating the bloodstream to deliver chemotherapy agents directly to tumor sites, thereby minimizing systemic side effects (Lee et al., 2023). Meanwhile, biofilm-removing microbots are being engineered to eradicate bacterial colonies on medical implants and dental surfaces (Kim et al., 2022). Automated systems are also emerging for precise injections, such as intravitreal therapies for ocular diseases, helping reduce clinician workload and human error (Zhou et al., 2024). Beyond clinical contexts, robots support public health surveillance and disease prevention. Prototypes like MIT’s “Luigi” sewage-sampling robot autonomously collect wastewater data to monitor community-level infections and anticipate outbreaks (MIT News, 2025). In precision agriculture, AI-guided robotic systems detect infected crops early, controlling plant disease spread and protecting global food security (FAO, 2023). Collectively, these robotic systems demonstrate the increasing convergence of automation, biotechnology, and artificial intelligence in safeguarding human and environmental health. By taking on tasks that are dangerous, repetitive, or biologically hazardous, disease-eliminating robots represent a pivotal advancement in the global strategy for infectious disease control and public health resilience. 7. Graphene Graphene is the world’s thinnest material, consisting in a single layer of carbon atoms arranged in a hexagonal honeycomb lattice. Despite its thinnest it is stronger than steel and diamond. In addition, graphene is flexible, transparent, conductive, light, selectively permeable and a 2D material. In summary it is a versatile material with many different applications and that has gained attention since its isolation in 2004 by Russian and Nobel prize scientists Andre Geim and Konstantin Nocoselov. (Larousserie, 2013) The characteristics of graphene make them an important player in the energy, construction, health and electronics sectors. In a deeper analysis, its high conductivity is valuable for battery life, autonomy and energy efficiency. Its lightness is suitable for manufacturing drone batteries, which reduce their weight, and the drone’s weight too. Graphene’s transparency and flexibility could be used in screen devices including cell phones, televisions or vehicles – Samsung already produced a flat screen with graphene electrodes. In addition, its high resistance and excellent heat and electric conductivity make them valuable for the light industry. Other sectors that are beneficial from graphene include the construction and manufacturing sector. For example, adding 1 g of graphene to 5 kg of cement increases the strength of the latter by 35%. Another example refers to Ford Motor Co., that is adding 0.5% of graphene to increase their plastic strength by 20%. (Wyss, 2022) Graphene has become a promising material, and it has been studied and tested to be used as a replacement or equivalent of silicon in microelectronics. It has been used in sports, like tennis rackets made by Head or in electric cars concepts like BASF and Daimler-Benz Smart Forvision. Bluestone Global Tech partnered with mobile phone manufacturers for the first graphene-based touchscreen to be launched in China. (Larousserie, 2013) Paint with graphene for a better thermal regulation in houses; bones, prosthesis, hearing aids or even diagnosis of diseases could also rely on graphene. (Repsol, 2025) Nowadays, its costs are high, but the graphene is going through a moment of intense academic research that surely in some years will end up with even more promising results and applications. Conclusion Together, these seven emerging technologies form a powerful snapshot of the future. Their diversity — spanning transportation, renewable energy, aquaculture, aerospace, robotics, and advanced materials — reflects the multi-sectoral nature of today’s global challenges. Yet they share a common purpose: to create more sustainable, efficient, and resilient systems capable of supporting a rapidly changing world. Wireless charging roads challenge the limits of mobility; ocean farming and wave energy reimagine how we use marine ecosystems; SpinLaunch and graphene redefine what is physically possible; and disease-eliminating robots transform public health. These innovations are still evolving, but they show that the solutions to some of humanity’s most pressing problems already exist — they simply need investment, scaling, and political will. By embracing these technologies and continuing to pursue scientific discovery, societies can accelerate the transition toward a cleaner energy future, safer communities, healthier ecosystems, and a more equitable and technologically advanced world.

1. Introduction: AI as a Reconfiguration of the Global Order Artificial intelligence (AI) has become one of the most influential factors shaping the contemporary international system. Major powers are competing to lead the new technological revolution that impacts the economy, security, foreign policy, defense, communications, and scientific innovation. The development of AI depends on three strategic inputs: 1. Human talent (research, data engineering, mathematics, computer science). 2. Computational capacity and access to large volumes of data. 3. Robust innovation ecosystems, with companies, universities, and aligned industrial policies. Global spending on artificial intelligence is expected to exceed USD 52 billion over the next three years, consolidating AI as the central axis of the Fourth Industrial Revolution (IDC, 2023; Stanford AI Index Report, 2024). 2. Talent as a Global Strategic Resource More than 60% of top AI researchers work in the United States, and about half of them are immigrants, primarily from China, India, Europe, and Iran (Stanford AI Index Report, 2024). The so-called brain drain is not merely an academic issue, but a geopolitical one: • States compete to attract talent through visas, high salaries, and access to frontier laboratories. • Innovation in AI depends on who concentrates the largest amount of specialized human capital. The United States dominates due to its ability to attract international researchers, while China compensates through massive investment and domestic talent production. 3. The United States Leads the AI Race for Three Main Structural Reasons 1. Innovation, talent, and industry: The United States leads in high-impact research publications and AI startups (more than 50% worldwide). Private investment exceeded USD 350 billion in 2023 alone. Key companies include Google, Meta, Microsoft, OpenAI, NVIDIA, Tesla, and IBM, among others. 2. Computational infrastructure and chips: The country concentrates the most advanced computational infrastructure and controls cutting-edge chips (such as the NVIDIA H100), a resource that China cannot yet produce at the same level. 3. AI and national security: The United States allocates more than 16 federal agencies and billions of dollars annually to AI development for defense, cybersecurity, and intelligence (White House AI Budget, 2024). 4. China: The Emerging Superpower on the AI Path China ranks second globally in the AI race but follows a more aggressive, centralized, and ambitious strategy. • Massive investment as state policy: China has pledged to invest more than USD 150 billion by 2030 in AI under its Next Generation Artificial Intelligence Development Plan (AIDP) (Government of China, 2017). • Domestic talent production: China trains more AI engineers than any other country. Annual graduates in science and engineering reach 4.7 million, compared to 600,000 in the United States (UNESCO, 2023). However, a significant portion migrates to the U.S. due to better research conditions. • China’s role in the global AI industry: China leads in AI-based facial recognition, with generative AI startups such as Baidu, SenseTime, Alibaba Cloud, and Tencent AI Lab. It produces massive numbers of publications, although with lower scientific impact than those from the United States. AI is widely implemented in governance, security, and smart cities. • The chip dilemma: China depends on advanced semiconductors produced only by Taiwan (TSMC), South Korea (Samsung), and the United States/Netherlands (ASML). • Export controls: Export restrictions imposed on China since 2022 limit its ability to train frontier models, although the country is making radical investments to achieve chip sovereignty. 5. Europe, India, Israel, Canada, and Other Relevant Actors • Europe: The United Kingdom, Germany, France, and the Netherlands generate a solid ecosystem in algorithmic ethics, digital regulation (AI Act), and applied research. • India: The world’s main hub of engineering talent and a global provider of technological services. • Israel: A powerhouse in cybersecurity and military AI, with per-capita innovation comparable to Silicon Valley. • Canada: The birthplace of deep learning (Geoffrey Hinton, Yoshua Bengio) and a strong center for basic research. 6. Africa on the AI Chessboard: Intentions, Challenges, and Opportunities Although Africa does not lead the AI race, its geopolitical role is growing rapidly for four strategic reasons. Africa is a major producer of critical minerals. AI depends on lithium, cobalt, graphite, and rare earth elements, and Africa holds 70% of the world’s cobalt reserves (in the DRC), as well as other strategic minerals in Zambia, Namibia, South Africa, and Mozambique. This places the continent in a key position within the supply chains for batteries, computers, and data centers. There is also a rapid expansion of digital infrastructure. China, through Huawei and ZTE, has built around 70% of Africa’s 4G network, as well as Ethiopia’s first smart data center and technology innovation hubs in Egypt, Kenya, and South Africa. Africa is entering the AI space through fintech, digital health, smart agriculture, and biometric systems. In terms of AI policy, African countries with formal AI strategies include Egypt, Rwanda, Kenya, and South Africa. • Threats and challenges: limited computational infrastructure, a deep digital divide, the risk of dependence on external technological solutions, the use of AI for political surveillance (as seen in Ethiopia and Uganda), and a shortage of specialized talent. 7. China and Africa: The Intersection of AI, Data, and Geopolitics China combines its role in AI with its influence in Africa through investments in digital infrastructure, the sale of surveillance systems, the construction of data centers, and technical training programs. This creates interdependence but also raises concerns: Africa could become dependent on Chinese systems that are difficult to replace. Data may become centralized on foreign platforms, and the risk of a technological debt trap adds to existing financial dependence. 8. AI, Regulation, and Global Governance The rapid expansion of AI calls for international treaties on data use, security standards, limits on military automation, and ethical regulations to protect civil society. Governance will be decisive in determining not only who leads, but also how this technology will be used in the coming decades. In this context, global AI governance has become a new field of geopolitical competition. While the European Union promotes a regulatory approach based on human rights and risk prevention, the United States favors market self-regulation and innovation, and China advances a model of state control and technological sovereignty. Multilateral organizations such as the UN, the OECD, and the G20 have begun discussing common principles, but there is still no binding international regime. The absence of clear rules increases the risks of an algorithmic arms race, the use of AI for mass surveillance, and the deepening of global inequalities in access to and control over technology. 9. Conclusions The United States leads due to innovation, global talent attraction, and computational capacity. China follows closely with a comprehensive state-led strategy and dominance in global digital infrastructure. Europe, India, Israel, and Canada contribute key elements to the global ecosystem. Africa, while not a leader, occupies an increasingly strategic role due to its resources, data, markets, and alliances. The race for AI will define not only the global economy, but also the balance of power in the international system of the 21st century. References -Stanford University.(2024). AI Index Report 2024.

The recently released Trump Administration’s National Security Strategy (NSS) has upended what had been the decades-long consensus about American foreign policy. Most notable in it is the Trump Administration’s prioritization of the Western Hemisphere as an American security concern, its deemphasis on defending America’s traditional European allies, its identification of China as far more of a threat than Russia, and its determination not to be drawn into conflicts in the Middle East and Africa. But while the 2025 Trump Administration National Security Strategy breaks with much of previous American foreign policy, the logic behind it is not something completely new. Even though the document makes no mention of him, the policy outlined in the NSS comports with what John Mearsheimer described in his influential book, “The Tragedy of Great Power Politics”, which was first published in 2001 and updated in 2014. In his book Mearsheimer declared that no nation has ever achieved global hegemony. According to Mearsheimer, America is the only country that has achieved predominant influence in its own region (the Western Hemisphere) and has also been able to prevent any other great power from dominating any other region. Mearsheimer wrote, “States that achieve regional hegemony seek to prevent great powers in other regions from duplicating their feat. Regional hegemons, in other words, do not want peers” (2014 edition, p. 41). Trump’s 2025 National Security Strategy has, whether knowingly or not, adopted these aims as well. It discusses the various regions of the world in the order of their priority for the Trump Administration: the Western Hemisphere first, followed by Asia (or Indo-Pacific), Europe, the Middle East, and lastly Africa. With regard to the Western Hemisphere, the NSS unambiguously calls for the restoration of “American preeminence in the Western Hemisphere,” and states, “We will deny non-Hemispheric competitors the ability to position forces or other threatening capabilities, or to own or control strategically vital assets, in our Hemisphere.” This is very much in keeping with what Mearsheimer described as America being a regional hegemon in the Western Hemisphere. As for the other four regions of the world, though, the Trump Administration seeks either to prevent any other great power from becoming predominant — or it doesn’t see this as a possibility that needs to be worried about. According to the NSS, the Middle East was a priority in the past because it was the world’s most important energy supplier and was a prime theater of superpower conflict. Now, however, there are other energy suppliers (including the U.S.) and superpower competition has been replaced by “great power jockeying” in which the U.S. retains “the most enviable position.” In other words: the Trump Administration does not see any other great power as able to become predominant in this region which is now less strategically important than it used to be anyway. Similarly, the NSS does not see any other great power as even seeking to become predominant in Africa. The NSS thus sees America’s main interests there as mainly commercial. By contrast, China is seen as a threat in the Indo-Pacific region. The NSS, though, discusses Chinese threats in the economic and technological spheres before turning to the military one. A continued U.S. military presence in the region is seen as important for preventing Chinese predominance. But Japan, South Korea, Taiwan, and Australia are all enjoined by the NSS to increase their defense spending in order to counter this threat. The NSS also identifies “the potential for any competitor to control the South China Sea” as a common threat that not only requires investment in U.S. military capabilities, “but also strong cooperation with every nation that stands to suffer, from India to Japan and beyond.” Unlike the Middle East and Africa, then, the NSS does identify a rival great power as striving for predominance in the Indo-Pacific region. Countering it, though, is not seen as just being America’s responsibility, but also that of other powerful states in the region. The strangest section in the 2025 NSS is the one on Europe. While acknowledging that “many Europeans regard Russia as an existential threat,” the NSS envisions America’s role as “managing European relations with Russia” both to “reestablish conditions of strategic stability” and “to mitigate the risk of conflict between Russia and European states.” This is very different from the decades-long U.S. policy of seeing America’s role as defending democratic Europe against an expansionist Soviet Union in the past and Putin’s Russia more recently. Indeed, the NSS’s claim that the European Union undermines “political liberty and sovereignty” and its welcoming “the growing influence of patriotic European parties” (in other words, anti-EU right wing nationalist ones) suggests that it is not Russia which the Trump Administration sees as a rival, but the European Union. The 2025 NSS does call for a “strong Europe…to work in concert with us to prevent any adversary from dominating Europe.” The NSS, though, seems to envision the European Union as either greater than or equal to Russia in threatening to dominate European nations. In his book, Mearsheimer did not envision the European Union as a potential great power rival to the U.S. Indeed, there isn’t even an entry for it in the book’s index. The way that the NSS envisions the world, though, comports with how Mearsheimer described America’s great power position: predominant in the Western Hemisphere and able to prevent any other great power from becoming predominant in any other region of the world. Mearsheimer, though, is a scholar who described the position in the world that he saw the U.S. as having achieved and which would seek to maintain. The 2025 NSS, by contrast, is a policy document laying out how the Trump Administration believes it can best maintain this position. And there is reason to doubt that it has done so realistically. Keeping non-Hemispheric great powers out of the Western Hemisphere will not be easy when there are governments there that want to cooperate with them. Further, devoting American resources to being predominant in Latin America when this will be resented and resisted could not only take away from America’s ability to prevent rival great powers from becoming predominant in other regions, but could counterproductively lead Latin American nations than have already done so to increase their cooperation with external great powers which the Trump Administration wants to avoid. Further, the Trump Administration’s efforts to reduce the influence of the European Union runs two risks: the first is that such an effort will succeed, but that the rise of anti-EU nationalist governments throughout the old continent results in a Europe less able to resist Russian manipulation and incursion. The second is that Trump Administration efforts to weaken the European Union backfire and result not only in a Europe united against American interference but unnecessarily emerging as a rival to the U.S. It would be ironic indeed if pursuing the NSS’s plan for upholding what Mearsheimer described as America’s ability to predominate over the Western Hemisphere combined with an ability to prevent any rival from predominating over any other region ended up undermining America’s ability to do either.

As international order evolves in the 21st century, strategic competition is increasingly shaped by technological frontiers and emerging domains of power. Unlike the unipolar moment following the Cold War, the contemporary landscape is defined by multipolarity, where major powers vie for influence across space, cyberspace, and biotechnology. Outer space has emerged not only as a frontier for exploration but also as a potential arena for resource acquisition and military projection, raising novel challenges for international law, security policy and cooperative governance. Examining interstellar phenomena in this context underscores the importance of preparedness, coordination, and risk management, even without assuming the presence of extraterrestrial intelligence, yet acknowledging the unprecedented nature of events that are pushing the boundaries of human observation. Humanity is gradually entering an era in which technological progress is reshaping our conception of cosmic exploration. As advancements in rocket propulsion, materials science, and observational astronomy accelerate, the prospect of humanity departing Earth towards other worlds becomes less a distant dream and more an inevitable chapter in our long-term evolution. The future of our species increasingly appears to be tied to the potential terraforming of new planets and celestial bodies, alongside the development of aerospace technologies capable of carrying us deeper into the cosmos. Within this transformative horizon, the Fermi paradox or the Dark Forest theory gains renewed relevance, challenging humanity to consider the existential filters that civilizations must surpass to survive, expand and potentially encounter other life forms. Yet, while such milestone may unfold centuries from now, the foundations of that future are being laid in the present. In the 21st century, specifically by the year 2026, humanity will become more capable of observing its immediate cosmic neighborhood. Modern telescopes and space-based observatories allow us to detect objects that for centuries have likely passed through our solar system unnoticed. Only within the brief span of our scientific maturation have we acquired the tools to identify interstellar objects, bodies originating beyond the solar system whose physical properties and trajectories challenge our existing frameworks. These objects, often catalogued as cometary in nature, possess characteristics that warrant careful study. Their unusual shapes, compositions, and velocities offer insights into environments beyond our interstellar cradle and, in some cases, raise questions about their natural origin or even the possibility of artificial extraterrestrial technology. As our detection capabilities improve, the arrival of each interstellar visitor represents not only a scientific opportunity but also a critical data point for understanding planetary security and defense. Consequently, their study urges nations to evolve towards a more serious and coordinated international framework capable of addressing the strategic, scientific, and existential implications of interstellar encounters. The emergence and Relevance of Interstellar Objects The scientific understanding of interstellar objects (ISOs) has evolved rapidly in recent years, propelled by technological advances and the unexpected discovery of bodies crossing the solar system on hyperbolic trajectories. Before 2017, the existence of such objects was largely theoretical, supported by models of planetary formation and stellar dynamics that predicted the ejection of debris during the early stages of planetary system evolution. These models implied that the Milky Way should contain vast populations of wandering fragments- comets, asteroids, and potentially more complex bodies such as extraterrestrial debris moving freely through interstellar space. Yet observational confirmation remained unattainable due to instrumental limitations. This changed with the detection of the first confirmed interstellar object, 1/Oumuamua, whose physical properties departed radically from known solar system bodies. Its non-gravitational acceleration, lack of a visible coma, and elongated shape challenged established models of cometary activity and asteroidal composition (Meech et al, 2017). The subsequent discovery of 2I/Borisov, a more conventionally cometary object, confirmed that the solar system is indeed exposed to material originating from other stellar environments (Jewitt & Luu, 2019). The contrast between both objects highlighted a key insight: ISOs are highly diverse, and their properties may reveal mechanisms and materials absent from our own planetary system. Advances in wide-field surveys, high-resolution instrumentation, and automated sky- monitoring systems have significantly expanded humanity´s capacity to detect and track ISOs. The increasing sensitivity of these tools marks a transition toward a new observational era in which interstellar detections may become more frequent. As a result, we are now able to observe the behavior of bodies entirely foreign to the solar system-objects whose trajectories, compositions, and signatures often defy established expectations and expose gaps in existing theoretical frameworks. This expanding observational capability not only advances scientific knowledge but also underscores the urgency of early warning detection. Because ISOs are typically identified within narrow observational windows, delayed characterization can lead to the loss of critical scientific and strategic information. Consequently, the growing presence of ISOs calls for enhanced global coordination, standardized protocols, and a more serious international approach to monitoring and interpreting near-Earth interstellar encounters. The Impact and Arrival of 3I/ATLAS The discovery of 3I/ATLAS, the third confirmed interstellar object entering our solar system, marks a significant milestone in modern astronomy. Unlike 1/Oumuamua and 2I/Borisov, whose observational windows were limited and partially constrained, 3I/ATLAS has provided a comparatively longer period for systematic study. Its hyperbolic trajectory, unusual photometric behavior, and non-standard luminosity variations have made it an object of exceptional scientific interest. While early observations suggest that while 3I/ATLAS shares key characteristics with known cometary bodies, its behavior reinforces broader findings that interstellar objects often display physical and dynamical properties that do not fit neatly within exiting taxonomies of solar system objects (Jewitt, 2023). The media response to 3I/ATLAS has been unprecedented. As with Oumuamua, the object rapidly became the subject of public fascination, sensational claims, and speculative narratives. News outlets, online forums, and social media ecosystems proliferated interpretations ranging from exotic physics to extraterrestrial probes. While much of this discourse lacks grounding in empirical evidence, its widespread circulation reflects a broader sociological trend: interstellar phenomena increasingly operate not only as a scientific event but also as catalysts for public, imagination, cultural anxiety, and geopolitical attention. As Kaku (2020) notes, humanity approaches a technological threshold where cosmic discovery intersects directly with public consciousness, provoking both curiosity and apprehension. From a scientific standpoint, researchers such as Loeb (2021) have emphasized that anomalous behavior in interstellar visitors should not be dismissed lightly. Although 3I/ATLAS currently appears consistent with a natural origin, its unique features-and the difficulty in categorizing ISOs-underscore the need for serious, methodical investigation. Loeb argues that humanity must abandon its complacency regarding the unknown nature of interstellar technologies or civilizations and instead adopt a posture of preparedness, open inquiry, and systematic risk assessment. In his view, phenomena like 3I/ATLAS are reminders that humanity is not isolated, and that contact-whether intentional or incidental—with non-human intelligence represents a real possibility with profound implications. The arrival of 3I/ATLAS has also highlighted the potential consequences of extraterrestrial technological encounters. Even in the absence of direct evidence of artificial origin, the mere ambiguity of such objects can trigger global destabilization through speculation, misinformation, or geopolitical competition. Historical examples such as the economic collapses of 1929 and 2008, the disruptive effects of the COVID-19 pandemic, and the global tensions surrounding major wars demonstrate how uncertainty-especially when amplified by media-can generate widespread instability. In this context, an interstellar object exhibiting unexplained characteristics could easily become a flashpoint for international tension, economic turbulence, or strategic miscalculation. Thus, beyond its scientific significance, 3I/ATLAS has brought renewed attention to the vulnerabilities and responsibilities of a species becoming increasingly aware of its cosmic environment. The object serves as a practical reminder that humanity must develop not only more advanced observational systems but also coordinated international frameworks for managing unexpected astronomical events. As we confront the possibility of encountering technologies or life beyond Earth, the world must adopt a more mature, structured approach to detection, interpretation, and global communication. This moment sets the stage for next critical dimension of the discussion, the implications of interstellar objects for planetary security and defense, and the urgent need to assess humanity’s readiness for cosmic contingencies. Toward a Multiplanetary Security Architecture Planetary security has grown increasingly complex as scientific capabilities expand toward detecting and characterizing interstellar objects whose origins and physical attributes lie beyond conventional astrophysical categories. Within the United Nations framework, existing mechanisms-such as COPUOS, the International Asteroid Warning Network (IAWN), and the Space Mission Planning Advisory Group (SMPAG) provide the foundational structure for global coordination on natural impact hazards (UN COPUOS, 2014). However, these institutions were established under assumptions limited to solar system derived natural threats, leaving them poorly equipped to address unknown interstellar phenomena. The Outer Space Treaty and subsequent conventions introduced broad principles on cooperation and peaceful use, but no anticipated scenarios involving technologically anomalous interstellar objects or potential artificial extraterrestrial artifacts, resulting in a significant global governance vacuum. These mechanisms are designed primarily for probabilistic, natural impact scenarios, not for interstellar objects exhibiting anomalous trajectories, non-gravitational accelerations or uncertain technological signatures. Recognizing this gap, recent scientific proposals-most notably those advanced by Loeb (2023)-have called for the development of a dedicated international coordination mechanism under the United Nations system for the study and assessment of interstellar objects. Rather than proposing a fixed institutional blueprint, these contributions emphasize the need for a structured platform capable of integrating scientific analysis, risk assessment, and transparent diplomatic communication in cases involving anomalous interstellar phenomena. Such proposals should be understood not as a definitive institutional prescription, but as forward as a definitive institutional prescription, but as forward-looking reference points for the type of governance architecture of international community must begin to contemplate. As humanity´s observational reach extends beyond the boundaries of the solar system; this governance gap becomes increasingly consequential. Interstellar objects introduce forms of uncertainty that existing planetary defense regimes-designed around predictable, solar system-derived threats were never Intended to manage, underscoring the need for flexible and adaptive legal frameworks capable of integrating scientific uncertainty into decision making processes. Within this emerging landscape, conceptual assessment tools have gained relevance as mechanisms to structure uncertainty rather than eliminate it. One illustrative example is the Interstellar Threat Assessment Scale (ITAS) proposed by Loeb (2024), which offers a simplified framework for evaluating interstellar detections based on observable characteristics rather than speculative intent. As its lower levels, the scale categorizes objects that behave consistently with natural interstellar debris, such as comet-like bodies exhibiting predictable physical and dynamic properties. Higher levels correspond to increasing degrees of anomaly-such as unexplained non-gravitational acceleration, unconventional trajectories, or geometries inconsistent with known natural formation processes. While the scale is not explicitly designed to identify extraterrestrial technology, it intentionally encompasses characteristics that fall outside established natural baselines. This design allows it to function across multiple scenarios, from rare or poorly understood natural phenomena to detections that may warrant closer scrutiny due to their atypical behavior. In this sense, the framework remains agnostic regarding origin, yet adaptable enough to support both conventional astrophysical analysis and precautionary assessments under conditions of elevated uncertainty. Importantly, it does not assert hostile intent or artificial origin, rather it operates as a risk-management tool that helps differentiate levels of scientific uncertainty and potential planetary relevance. Approached in this manner, such frameworks contribute to the evolution of international space governance by providing a shared analytical language for policymakers, scientific institutions, security agencies and statecraft-oriented decision-makers. By standardizing how uncertainty is assessed and communicated, they reduce fragmented national interpretations, limit reactive or militarized responses, and promote cooperative, evidence-based decisions. Decision-making under conditions of incomplete information. This process reflects a broader need for international space law to evolve dynamically. However, the governance of interstellar risk cannot rely solely on conceptual models or isolated scientific initiatives. It requires a genuinely planetary response that integrates the full spectrum of contemporary technological, institutional, and political capacities. International legislation governing outer space must be adaptive and evolutionary, capable of responding to emerging scientific realities. Artificial intelligence, real-time global surveillance networks, and autonomous detection algorithms must be incorporated into a unified planetary architecture capable of identifying and characterizing interstellar objects far earlier than current capabilities allow. Equally important is the sustained collaboration among major space agencies-including NASA, ESA, CNSA, ISRO, Roscosmos, and JAXA- alongside private actors such as SpaceX, Blue Origin, and emerging aerospace enterprises, whose technological capabilities and rapid innovation cycles are increasingly central to space governance. Equally critical is great-power cooperation. From a realist perspective, the international system remains defined by competition, power asymmetries, and strategic mistrust. Yet planetary defense represents a rare domain in which shared existential vulnerability can partially override zero-sum logic. The detection of an anomalous interstellar object must never become a catalyst for geopolitical rivalry or strategic miscalculation, but rather an opportunity for transparent scientific collaborations and coordinated global response. In an international order strained by power competition, planetary security stands as one of the few areas where shared survival interests necessitate shared responsibility. Ultimately, interstellar objects compel humanity to transcend political fragmentation and adopt a forward- look global strategy. Building a resilient planetary security architecture requires the integration of scientific expertise, adaptive international governance, technological innovation, and coordinated commitment of state and private actor alike. Whether future interstellar encounters prove benign or reveal unprecedented anomalies, preparedness is not speculation, it is an essential step in the evolution of humanity´s role within the cosmos.

1. Introduction The relationship between China and Africa has become one of the most influential geopolitical dynamics of the 21st century. For China, Africa represents a strategic source of raw materials, an emerging market of 1.4 billion people, and a key partner for strengthening its political influence within international organizations. For Africa, China has represented an alternative to traditional Western financing, capable of offering infrastructure, investment, and trade openness without explicit political conditions. However, this relationship has also generated debates regarding economic dependency, debt risks, and the real balance between mutual benefit and power. 2. Theoretical Framework: Realism, Core–Periphery, and Interdependence 2.1 Realism From a realist perspective, China’s engagement can be interpreted as a strategy to strengthen state power, secure energy resources, increase its influence vis-à-vis the United States, and promote international recognition of the People’s Republic of China over Taiwan. 2.2 Core–Periphery Theory Following Wallerstein, the China–Africa relationship reflects a core–periphery dynamic: China, as an industrialized country with high technological capacity, occupies the core, while African states, as exporters of raw materials, occupy the periphery. However, China seeks to project a narrative of mutual benefit in order to differentiate itself from former European colonial powers. 2.3 Power Transition Theory China’s rise demonstrates how an emerging power can alter the international system. Examples include Deng Xiaoping’s economic opening (1978), accelerated industrialization, and strategic global integration through the Belt and Road Initiative (BRI). 3. Historical Evolution of the China–Africa Relationship The formal relationship was consolidated in the 1960s, but it was significantly strengthened in the 21st century through mechanisms such as the Forum on China–Africa Cooperation (FOCAC), established in 2000. This period has been characterized by billions of dollars in foreign direct investment and the integration of African ports into the New Silk Road. Africa came to view China as a non-colonial partner, while China found diplomatic support that enabled it to occupy China’s seat at the United Nations in 1971 as the “legitimate China.” 4. Key Data and Statistics of the China–Africa Economic Relationship From a realist perspective, the volume of China’s trade and investment in Africa does not respond solely to economic dynamics, but rather to a deliberate strategy of accumulating structural power. Secured access to oil, critical minerals, and strategic metals is essential for sustaining China’s industrial growth and reducing its vulnerability to external disruptions, particularly in a context of systemic competition with the United States. Likewise, from a core–periphery perspective, the composition of bilateral trade reproduces classic patterns of unequal exchange, in which Africa continues to export primary goods with low value added while importing manufactured goods and technology. Although China discursively distances itself from European colonialism, the data suggest that the structure of exchange maintains asymmetries that may limit the autonomous industrial development of the African continent. 4.1 Bilateral Trade Trade between China and Africa reached USD 282 billion in 2023, making China the continent’s largest trading partner. African exports to China consist of approximately 70% oil, minerals, and metals. China primarily exports machinery, textiles, electronics, and vehicles. 4.2 Investment and Infrastructure Projects Between 2013 and 2023, China financed more than 10,000 km of railways, 100,000 km of roads, and over 100 ports in Africa. China is responsible for approximately 31% of total infrastructure investment on the continent. 4.3 Debt Africa’s debt to China amounts to approximately USD 73 billion. In countries such as Angola and Kenya, Chinese debt accounts for more than 20% of their total external debt. 5. Country-Specific Examples The cases of Ethiopia, Kenya, Angola, and Zambia demonstrate that China’s cooperation is not homogeneous, but rather strategically differentiated according to each country’s geopolitical and economic importance. Ethiopia, as Africa’s diplomatic hub and host of the African Union, is key to China’s political projection on the continent. Kenya and Angola stand out for their logistical and energy value, respectively, while Zambia illustrates the financial limits of this model of cooperation. From the perspective of interdependence theory, these relationships generate mutual benefits, but in an asymmetric manner: China diversifies trade routes, secures resources, and expands its influence, while African countries obtain infrastructure, often at the cost of increased financial vulnerability. In this sense, Africa is not merely a passive recipient, but a central space in the architecture of China’s global rise. 5.1 Ethiopia: A Symbol of Cooperation Ethiopia is one of China’s main allies in Africa. The Addis Ababa–Djibouti railway represents an investment of approximately USD 4 billion, almost entirely financed by China. In 2022, Ethiopia exported more than USD 200 million in agricultural and mineral products to China. 5.2 Kenya: Infrastructure and Debt The Mombasa–Nairobi railway, valued at approximately USD 3.6 billion, is the most expensive infrastructure project in Kenya’s history. Kenya owes China around USD 6.3 billion, equivalent to nearly 20% of its external debt. 5.3 Angola: Oil as Collateral Angola is one of China’s main oil suppliers. A significant portion of Angola’s debt to China is repaid through oil shipments, creating a form of structural dependency. 5.4 Zambia: Risk of Over-Indebtedness Zambia was the first African country to fall into default in the post-pandemic period. China is its principal bilateral creditor, with more than USD 6 billion in outstanding loans. 6. The New Silk Road in Africa Africa’s incorporation into the Belt and Road Initiative (BRI) should be understood as an extension of China’s broader project to reconfigure the international system. Maritime and port corridors in East Africa not only facilitate trade, but also reduce China’s dependence on routes controlled by Western powers, thereby strengthening its strategic autonomy. East Africa is central to the maritime expansion of the BRI. It offers strategic ports in Djibouti, Kenya, Tanzania, and South Africa, as well as new maritime corridors that allow China to connect Asia with the Red Sea and the Mediterranean. For African countries, this integration represents greater commercial connectivity, access to modern infrastructure, and regional logistical opportunities. From the perspective of power transition theory, the BRI in Africa constitutes a key instrument through which China consolidates its position as an emerging global power, gradually displacing the traditional influence of Europe and the United States on the continent. For Africa, this integration offers opportunities for connectivity and development, while simultaneously reinforcing its centrality as a space of global geopolitical competition. 7. Criticisms of China’s Role in African Debt 7.1 Accusations of “Debt-Trap Diplomacy” China is accused of using large-scale loans to obtain strategic influence, as illustrated by the case of the Hambantota Port in Sri Lanka, although it lies outside the African continent. Similar concerns exist in Kenya regarding the port of Mombasa. Accusations of “debt-trap diplomacy” must be analyzed beyond normative discourse. While not all cases confirm a deliberate strategy of financial domination, the concentration of debt in a single creditor limits the room for maneuver of African states, especially in times of crisis. From a structural perspective, debt becomes a mechanism of indirect influence that can translate into political concessions, preferential access to resources, or diplomatic alignments favorable to China in international forums. Nevertheless, it is also true that responsibility lies partly with African governments, whose negotiation capacity and strategic planning are decisive in avoiding scenarios of prolonged dependency. 7.2 Lack of Transparency Loan contracts may include confidentiality clauses, resource-backed guarantees, and high penalties for renegotiation. 7.3 Long-Term Dependency For fragile states, the concentration of debt in a single creditor limits political and economic autonomy over the long term. 7.4 China’s Position China rejects these accusations and maintains that it has renegotiated and forgiven billions of dollars in debt. It argues that its loans are long-term, carry moderate interest rates, and that its cooperation is based on “mutual benefit” rather than imposition. 8. Conclusion The China–Africa relationship is complex, strategic, and multidimensional. It presents significant opportunities for African development, but also poses risks related to debt, economic dependency, and political influence. The challenge for Africa is to negotiate from a stronger position, diversify its partners, and ensure that agreements with China translate into sustainable long-term development. The core–periphery relationship between China and Africa constitutes one of the most relevant axes of the contemporary international system. Through trade, investment, infrastructure, and financing, China has consolidated itself as a central actor in African development while simultaneously strengthening its global projection as an emerging power. For African countries, this relationship offers real opportunities for growth, modernization, and integration into the global economy. However, these benefits will only be sustainable if accompanied by national strategies aimed at productive diversification, financial transparency, and collective negotiation vis-à-vis external actors. Looking toward the future of the international system, China–Africa cooperation reflects a transition toward a more multipolar order, in which emerging powers challenge traditional structures of power. Africa, far from being a peripheral actor, is emerging as a decisive space in the redefinition of global balances. The central challenge will be to transform this centrality into autonomy and sustainable development, avoiding the reproduction of old dependencies under renewed narratives. References - Castro, G.
