China’s dominance of the rare-earth mineral supply chain gives Beijing a powerful tool of economic coercion against rival states. Vital rare-earth minerals like cobalt, copper, lithium, and graphite are crucial inputs for products used in daily life and in national defense. These include electric vehicles, solar panels, military aircraft, and semiconductors. Ensuring control over the supply chains of these critical minerals is becoming a key aspect of geopolitical rivalry. 

Much of this competition is focused on Africa, which holds about 30 percent of the world’s mineral reserves. China has already secured dominant positions in essential parts of these supply chains, recognizing the strategic importance of controlling access to these critical resources. 

China produces nearly 70 percent of the world’s rare earth minerals, and has reinforced this position through deliberate efforts to control every stage of the critical mineral supply chain. This process begins long before extraction, with Chinese banks and engineering firms securing involvement. Beijing then extends that control to the project’s end, pairing ownership of mines with ownership of the railways, roads, and ports through which these materials move. The result is a supply system in which China extracts, refines, and exports minerals from Africa which ensures that, in many cases, raw materials move on Chinese terms. 

China’s dominance in the rare earth mineral trade stems from its strategic approach to mineral supply chains, not just profit. This allows Beijing to maintain long-term control of mines during economic downturns. This is a luxury that profit-driven Western competitors do not have. Chinese firms enter the market fully prepared and offers financing, workforce, equipment, and logistics that often gain significant control over project execution from the start. This strategy has helped Beijing achieve “processing dominance,” meaning control over the refining system to the point that winning a mining contract in Africa does not ensure independence from Chinese supply chains. Although China produces only about 10 percent of the world’s lithium, cobalt, and copper, it controls roughly 40-90 percent of the refining capacity for these materials. Therefore, a Western company extracting ore in sub-Saharan Africa has not truly succeeded if the ore must be processed through a Chinese refinery. For the United States, this distinction has far-reaching consequences beyond market competition. 

The U.S. is highly exposed to supply chain disruption risks because critical minerals have uses that extend far beyond consumer products. They are key components of systems essential to national defense, including F-35 fighter jets, Virginia- and Columbia-class submarines, Tomahawk missiles, radar systems, Predator unmanned aerial vehicles, and more. The U.S. maintains only one domestic rare earth mine, possesses minimal refining infrastructure, and relies on China for 70% of rare earth imports. Expanding domestic mining and refining capacity requires significant capital investment and highly specialized expertise, limiting the speed at which domestic production can realistically offset exposure risks. The result is a situation in which the U.S. defense industrial base is significantly dependent on a strategic adversary for materials it cannot easily replace, and which are essential to the production and sustainment of advanced military capabilities. 

The risks of relying on a strategic adversary like China for materials vital to American national security are clearly shown by the China–Japan Rare Earths dispute of 2010. In September 2010, a Chinese fishing boat collided with two Japanese Coast Guard ships in the East China Sea, leading to the arrest and detention of the boat’s captain. In reaction, the Chinese government stopped exporting critical minerals to Japan. Tokyo, which depended on Beijing for nearly 90 percent of its rare earth mineral imports, saw prices for these goods rise nearly 10-fold in the year after the incident. Although the United States and Japan are in different positions within global supply chains, Japan’s experience demonstrates the broader strategic dangers that arise when a country becomes heavily dependent on a geopolitical rival for key resources. 

The coercive value of rare earth dominance lies not only in China’s ability to deny access but also in the threat of disruption. Even the possibility of export restrictions can drive price volatility, delay industrial production, complicate defense procurement, and undermine long-term investment planning. Japan’s response to the 2010 dispute reveals that dependency on rare earth elements is not unavoidable. Japan’s proactive approach included investing in recycling technologies, developing alternative materials, diversifying supply chains through overseas mining projects in Australia and other countries, and building stockpiles to secure reserves. As a result, Tokyo reduced its reliance on Chinese rare earths by about 30 percent, demonstrating that policy actions can yield tangible results. More broadly, Japan’s experience underscores a key truth of modern strategic competition: dependence on an adversary for vital materials can create vulnerabilities that go beyond economics. Washington and its partners should take notice.

Semiconductors: The Backbone of Cyber Power

Semiconductors enable the computing power that drives everything from commercial applications to military operations. Advanced chips are critical for AI, autonomous systems, and national security infrastructure. As nations race to secure technological dominance, control over semiconductor production becomes a central element of cyber deterrence.

The production of semiconductors is extraordinarily complex and relies on a global supply chain. No single country is self-sufficient in this domain. Manufacturing processes demand rare metals, precision tools, and expertise spanning Japan, the Netherlands, South Korea, Taiwan, and the United States. Companies like TSMC (Taiwan), Intel (United States), and Samsung (South Korea) dominate the field, with TSMC leading in advanced chip production. Advanced Semiconductor Materials Lithography (ASML), a Dutch company, monopolizes the production of extreme ultraviolet (EUV) lithography machines, critical for fabricating cutting-edge chips.

The Strategic Importance of Semiconductors

Semiconductors are more than just a commercial product—they are a strategic resource that nations leverage to project power in cyberspace. The United States has long recognized the importance of staying ahead in chip technology, aiming to maintain at least a two-generation lead over adversaries like China. This lead is not just about technological superiority but is also about cyber deterrence.

Cyber deterrence relies on the ability to defend, retaliate, or disrupt an adversary’s cyber capabilities. Advanced semiconductors provide the computational power necessary for AI-driven cybersecurity systems, intelligence gathering, and offensive cyber operations. For example, autonomous systems in modern warfare require sophisticated chips to function effectively. If a nation lacks access to such technology, its cyber capabilities are significantly weakened.

China’s Vulnerability and Response

China, despite being the second-largest economy and a global manufacturing powerhouse, has a surprising weakness in the semiconductor supply chain. It spends more on importing chips than oil and relies heavily on foreign suppliers, including its geopolitical rivals. This dependency creates a critical vulnerability in its cyber and AI ambitions.

Recognizing this weakness, China launched massive initiatives to achieve self-sufficiency in semiconductor production. However, the barriers to entry are steep. Manufacturing cutting-edge chips requires material purity at a level of 99.99999 percent, and even a minor defect can render a chip unusable. The complexity of the global supply chain further complicates China’s efforts. For instance, ASML’s EUV lithography machines, essential for advanced chip production, are legally restricted from being sold to China under export control agreements led by the United States.

China’s strategy focuses on targeting chokepoints in the supply chain while ramping up domestic production of less advanced chips. Success in this endeavor would significantly alter the balance of power in cyberspace, enabling China to compete more effectively in AI and cyber operations. However, for now, its reliance on foreign technology remains a significant deterrent.

US Strategy: Strengthening Deterrence Through Dominance

The United States took proactive steps to secure its dominance in semiconductor technology as part of its cyber deterrence strategy. Legislation like the 2022 CHIPS and Science Act provides billions in subsidies to bolster domestic chip production. The US also works to integrate government, industry, and academia to address challenges in manpower, education, and research and development.

The American approach to cyber deterrence is twofold. First, it seeks to maintain its technological edge by investing in leading-edge chips while ensuring a robust supply of legacy nodes for essential systems. Second, it actively restricts access to critical technologies for adversaries. For instance, since 2018, the export of EUV lithography machines to China has been prohibited, a move aimed at stalling China’s progress in advanced semiconductor manufacturing.

This strategy aligns with the broader geopolitical framework, where supply chain control becomes a tool for exerting influence. By leveraging its dominance in semiconductors, the US can deny adversaries the tools they need to compete in AI-driven cyber capabilities, thereby strengthening its cyber deterrence posture.

The Role of AI and Advanced Chips in Cyber Deterrence

AI is a cornerstone of cyber operations, from defensive systems that identify and mitigate threats to offensive tools that exploit vulnerabilities in adversarial networks. The power of AI is directly tied to the availability of advanced chips, which enable greater computational efficiency and data processing.

In the AI arms race, semiconductors are the critical enabler. Nations with access to advanced chips can train larger models, process more data, and deploy more sophisticated algorithms. Conversely, those lacking access are at a significant disadvantage. This dynamic emphasizes the importance of securing semiconductor supply chains as part of national cyber deterrence strategies.

Geopolitics and the Future of Cyber Deterrence

The geopolitical implications of semiconductor dominance extend beyond cyber operations. Control over the chip supply chain influences alliances, trade policies, and even the balance of power in global governance. Governments increasingly push nations and companies to choose sides, creating a polarized landscape.

The US and its allies currently hold a strong position, but the race is far from over. As China invests heavily in self-sufficiency, the stakes in the semiconductor arms race continue to rise. The future of cyber deterrence will depend on the ability of nations to secure their supply chains, innovate in chip technology, and adapt to the rapidly evolving landscape of AI and cybersecurity.

Conclusion

Semiconductors are not just a technological marvel—they are a strategic weapon in the cyber domain. As nations compete for supremacy, control over chip production and supply chains will play a pivotal role in shaping cyber deterrence strategies. The US, with its technological edge and integrated approach, aims to maintain its dominance, while China’s efforts to overcome its vulnerabilities will redefine the global order. In this high-stakes competition, the invisible hand of the market is guided by the visible hand of governments, ensuring that semiconductors remain at the heart of cyber power.
