Rare Minerals And The New Geometry Of US–China Power – OpEd
By Aishwarya Sanjukta Roy Proma
Rare earth minerals now occupy a central place in strategic policy debates, appearing in discussions about electric vehicles, renewable energy, semiconductor supply chains, and advanced weapons systems. Their importance does not stem from scarcity alone. It stems from concentration.
Rare earths comprise 17 elements, including neodymium, dysprosium, and terbium. These elements enable high-strength permanent magnets, precision guidance systems, radar components, and energy-efficient motors. Deposits exist in the United States, Australia, Canada, and parts of Africa. The constraint lies in separation and refining. Processing rare earth ore into usable oxides and metals requires complex chemical techniques, environmental management, and technical expertise. Over the past three decades, China built that capacity at scale.
China accounts for the majority of global rare earth refining and an even larger share of permanent magnet production. Even when ore is mined outside China, it often travels there for processing. This structural position gives Beijing leverage within critical manufacturing chains. It does not amount to absolute control, but it shapes the terms of trade. The strategic implications first became visible in 2010. Following a maritime dispute between China and Japan in the East China Sea, rare earth shipments to Japan were disrupted. Prices rose sharply. Japanese manufacturers faced uncertainty in electronics and automotive production. Although Beijing denied an official embargo, the episode signaled that export flows could shift in response to political tensions.
In Washington, that incident reinforced a broader reassessment of supply chain exposure. Rare earths entered national security reviews. The Department of Defense examined dependencies within weapons platforms, including the F-35 fighter jet and precision-guided munitions. Policy debates began to link mineral supply with strategic autonomy. The United States had allowed its own rare earth industry to contract in the 1990s and early 2000s, partly because environmental compliance raised costs. Market logic favored Chinese production. Strategic logic now points elsewhere. The reopening of the Mountain Pass mine in California marked a first step. Mining alone does not resolve dependence. Until recently, much of the ore extracted at Mountain Pass was shipped to China for separation. Building domestic refining capacity requires capital, regulatory approval, and sustained demand. Coordination with partners such as Australia and Canada forms part of a diversification strategy.
China’s approach reflects long-term planning. Beginning in the 1990s, Beijing identified rare earths as a strategic sector. It consolidated smaller producers into large state-backed groups, imposed production quotas, and tightened export licensing. These measures aimed to curb environmental damage, stabilize prices, and increase bargaining power. They also aligned with a broader industrial strategy to move Chinese firms up the value chain from raw material extraction to high-technology manufacturing.
Rare earths now sit at the intersection of climate policy and defense policy. Electric vehicle motors rely on neodymium-iron-boron magnets. Wind turbines require similar components to maintain efficiency at scale. Advanced missile systems and radar arrays incorporate rare earth alloys for heat resistance and signal processing. As governments pursue decarbonization targets and modernize military forces, demand rises across both civilian and defense sectors.
The analogy to oil circulates in policy commentary. It captures one dimension of the issue: resource concentration can generate leverage. But rare earths differ from oil in key respects. Oil is combusted. Rare earth elements are embedded in durable goods. Their markets are smaller and less liquid. Price spikes can occur rapidly because volumes are limited. Substitution is possible in certain applications, though often at the cost of efficiency. The comparison clarifies strategic stakes but obscures industrial complexity.
States use economic instruments to pursue strategic objectives. Export controls, investment screening, and industrial subsidies are part of this toolkit. In recent years, the United States has expanded restrictions on advanced semiconductor exports to China and tightened review of outbound investment. Rare earth policy fits within this broader shift, away from the assumption that open markets alone can guarantee supply security.
China has strengthened oversight of critical mineral exports and signaled that resource controls remain available as policy instruments. Beijing also invests in overseas mining projects in Africa and Latin America, with infrastructure financing through state-linked banks supporting access to raw materials. Allies have recalibrated their own positions. The European Union adopted the Critical Raw Materials Act, which sets benchmarks for domestic extraction, processing, and recycling. Japan increased investment in overseas partnerships and stockpiles after the 2010 episode. These policies share a premise: concentrated supply chains generate risk, and diversification reduces vulnerability even if it raises costs in the short term.
Environmental considerations complicate this transition. Rare earth processing generates chemical waste and radioactive byproducts. Regulatory review can delay projects for years. Policymakers face a trade-off between rapid diversification and environmental safeguards. China’s early dominance partly reflected its willingness to absorb environmental costs that other jurisdictions avoided. Market forces alone are unlikely to resolve the imbalance quickly. Building separation plants and magnet factories requires technical expertise that accumulated in China over decades. Skilled labor, supplier networks, and economies of scale reinforce existing advantages. Public funding can accelerate development, but industrial ecosystems take time to mature.
Complete dependence is unlikely to persist indefinitely. Australia’s Lynas Rare Earths has expanded processing capacity outside China. The United States has supported pilot projects for domestic magnet manufacturing. Recycling technologies may recover rare earth elements from end-of-life electronics and turbines, though current volumes remain limited.
The rivalry between the United States and China unfolds within constraints. Neither side can sever economic ties without a high cost. Policy language has shifted, though. Governments now accept higher production costs in exchange for reduced exposure to disruption. Industrial policy has regained legitimacy in advanced economies. Rare earths connect climate ambitions, digital infrastructure, and military modernization. They show how economic concentration can translate into strategic influence. They also reveal the limits of simple resource analogies. Unlike oil, rare earth elements operate within layered supply chains spanning mining, separation, alloy production, magnet fabrication, and final assembly.
The next phase of competition will hinge on capacity and coordination. If the United States and its partners establish viable refining and magnet industries at scale, the leverage associated with concentration will diminish. If projects stall due to regulatory delay, cost overruns, or weak demand signals, dependence will continue. China’s position rests not only on mineral deposits but on accumulated industrial depth. That depth cannot be replicated quickly. Transparent markets, environmental standards, and multilateral coordination could reduce the risk of coercive leverage. Whether such arrangements emerge remains uncertain. Strategic mistrust complicates cooperation.
The United States seeks to reduce vulnerability without abandoning global integration. China aims to preserve industrial advantages while projecting influence. The outcome will depend on sustained investment, regulatory choices, and alliance management. Beneath the surface of everyday devices, a quiet contest over minerals continues to reshape geopolitics.
