The world’s transition to clean energy runs through a single country. China controls 90% of rare earth supply chain processing[s], creating a vulnerability that threatens electric vehicles, wind turbines, and defense systems alike. These 17 metallic elements power the magnets in EV motors, the generators in offshore wind farms, and the guidance systems in precision munitions. Without them, the green transition stalls.
The concentration is striking. China accounts for roughly 70% of global rare earth mining, 87% of processing, 91% of refining, and 90% of permanent magnet production[s]. The European Union sources 98% of its rare earth magnets from China[s]. This is not a minor dependency. Over 80% of large European firms are no more than three intermediaries away from a Chinese rare earth producer[s].
A Rare Earth Supply Chain Built Over Decades
China’s dominance did not happen overnight. Since the 1980s, Beijing has invested billions in building an integrated rare earth supply chain[s]. State support, cheaper labor, and looser environmental standards allowed Chinese producers to undercut American competitors[s]. China increased production from 31,000 metric tons in 1994 to 270,000 metric tons in 2024[s].
The strategy was geopolitical, not purely economic. As one analyst noted, Beijing’s rationale for absorbing this originally American industry was more about strategic positioning than profit margins[s]. China progressively moved from extraction to separation, refining, metallurgy, and magnet manufacturing. In the 1990s, Japan and the United States led magnet production. By the early 2010s, China had acquired the last missing technologies[s].
Demand Is About to Surge
The timing could not be worse for Western economies. Demand for rare earth elementsSeventeen metallic elements with unique magnetic and conductive properties essential for modern electronics and defense systems. is expected to grow 400% to 600% over the coming decades[s]. The International Energy Agency projects rare earth demand could increase sevenfold by 2040 under its Sustainable Development Scenario[s]. Electric vehicles require six times more critical mineralsRaw materials essential for economic security and national defense, often subject to supply chain vulnerabilities. than conventional cars[s].
Supply gaps are already emerging. Global demand for neodymium, essential for permanent magnetsMagnets that retain their magnetic field without external power. The primary application of rare earth elements, used in EV motors and wind turbine generators., is projected to exceed supply by 250% by 2030[s]. Offshore wind turbines require 80 to 200 kilograms of rare earths per megawatt of capacity[s]. A single F-35 fighter jet contains over 400 kilograms of materials with rare earth content[s].
Beijing Has Already Used This Leverage
China has demonstrated willingness to weaponize rare earth exports. In 2010, following a maritime dispute over islands in the East China Sea, Beijing halted rare earth exports to Japan for two months[s]. The embargo choked Japanese industries that relied on high-tech manufacturing materials.
More recently, in April 2025, China imposed export controlsGovernment regulations restricting the transfer of sensitive technologies, materials, or data to foreign entities for national security reasons. on seven heavy rare earth elements in response to U.S. tariffs[s]. In October 2025, Beijing expanded these controls to require foreign firms to obtain approval for shipping magnets containing as little as 0.1% Chinese-sourced material[s]. Though suspended until November 2026, the controls signaled Beijing’s willingness to leverage its rare earth supply chain dominance[s].
The economic impact was immediate. Rare earth prices in the EU rose up to six times following the restrictions[s]. In early 2026, China continued restricting shipments of export-controlled rare earth compounds and metals to the United States[s].
Can the West Diversify?
The geological resources exist. Rare earths are not actually rare; they exist in deposits across the United States, Australia, Vietnam, Brazil, and Madagascar[s]. Australia has the world’s fourth-largest reserves and hosts the only significant producer of heavy rare earthsA subset of rare earth elements including terbium, dysprosium, and others, critical for advanced magnets and defense applications. outside China, Lynas Rare Earths[s].
The problem is processing infrastructure. Building an alternative rare earth supply chain requires massive investment over many years. Mining industry veterans estimate it could take a decade to build competitive domestic capacity[s]. New mining projects take an average of 15.5 years from discovery to production[s]. In the United States, permitting alone averages 16 years[s].
Governments are now mobilizing. In October 2025, the United States and Australia signed an $8.5 billion framework to accelerate rare earth projects[s]. The EU’s Critical Raw Materials Act sets targets for domestic extraction, processing, and recycling by 2030[s]. But these efforts face a fundamental challenge: the world will likely remain dependent on Chinese rare earth processing for years to come[s].
The Green Transition’s Uncomfortable Truth
The clean energy transition depends on materials controlled by a strategic competitor. Every electric vehicle motor, every wind turbine generator, every missile guidance system relies on a rare earth supply chain that Beijing can disrupt at will. This is the geopolitical reality that Western policymakers must now confront.
Diversification is possible but slow. Recycling helps but cannot meet surging demand. The critical mineral demand needed to meet climate pledges could quadruple by 2050[s]. Until alternative supply chains mature, the green transition remains hostage to a monopoly built over 30 years of strategic investment.
The global rare earth supply chain presents a textbook case of strategic chokepoint economics. China controls approximately 90% of rare earth processing capacity[s], with corresponding dominance across extraction (71%), processing (87%), refining (91%), and permanent magnet production (90%)[s]. The 15 lanthanidesThe 15 metallic elements with atomic numbers 57-71. Together with scandium and yttrium, they make up the 17 rare earth elements. plus scandium and yttrium (17 rare earth elementsSeventeen metallic elements with unique magnetic and conductive properties essential for modern electronics and defense systems. in total) are irreplaceable in neodymium-iron-boron permanent magnetsMagnets that retain their magnetic field without external power.

European Central Bank economists have mapped this exposure: over 80% of large EU firms sit within three intermediaries of a Chinese rare earth producer[s]. The EU imports 98% of its rare earth magnets from China[s]. Light rare earths (neodymium, praseodymium) and heavy rare earthsA subset of rare earth elements including terbium, dysprosium, and others, critical for advanced magnets and defense applications. (dysprosium, terbium) flow through processing bottlenecks that took Beijing three decades to construct.
Historical Development of the Rare Earth Supply Chain
China’s rare earth dominance resulted from sustained industrial policy beginning in the 1980s[s]. Production scaled from 31,000 metric tons (1994) to 270,000 metric tons (2024)[s]. Chinese producers systematically undercut competitors through state subsidies, lower labor costs, and regulatory arbitrageThe practice of exploiting differences in regulatory frameworks between jurisdictions to minimize compliance costs or avoid oversight. on environmental standards[s].
The value chain capture followed a deliberate sequence. Beijing moved from extraction to separation, refining, metallurgy, and finally magnet manufacturing. The acquisition of Magnequench (General Motors’ magnet subsidiary) by Chinese entities in 1997 marked a turning point[s]. Japan’s magnet producers relocated production to China in exchange for market access, transferring the remaining technical gaps by the early 2010s[s]. By 2019, China produced 92% of global rare earth permanent magnets[s].
Demand Projections and Supply Constraints
IEA modeling projects rare earth demand increasing threefold (STEPS) to sevenfold (SDS) by 2040[s]. Broader estimates place rare earth element demand growth at 400% to 600% over coming decades[s]. Critical mineral demand overall could quadruple by 2050 under announced climate pledges[s].
Specific supply gaps are acute. Neodymium demand is projected to exceed supply by 250% by 2030; praseodymium by 175%[s]. Offshore wind installations require 80 to 200 kg of rare earths per MW[s]. EVs demand six times the critical mineral input of internal combustion vehicles[s]. Defense applications compound civilian demand: an F-35 contains over 400 kg of rare earth materials[s].
Export Control Mechanisms and Precedents
Beijing has demonstrated willingness to deploy rare earth supply chain leverage as a coercive instrument. The 2010 Japan embargo, triggered by territorial disputes in the East China Sea, halted exports for two months[s]. The 2025 export control regime introduced more sophisticated mechanisms.
In April 2025, China imposed licensing requirements on seven heavy rare earth elements (samarium, gadolinium, terbium, dysprosium, lutetium, scandium, yttrium) plus compounds and magnets[s]. October 2025 controls extended extraterritorially: foreign firms require Chinese approval to export magnets containing 0.1% Chinese-sourced material or produced using Chinese technology[s]. This mirrors the U.S. Foreign Direct Product Rule applied to semiconductors.
Market response was severe. EU rare earth prices increased up to sixfold following restrictions[s]. Though the October controls were suspended until November 2026, early 2026 data shows China continuing to restrict export-controlled rare earth compound and metal shipments to the United States[s].
Alternative Supply Chain Development
The geological constraint is overstated; the processing constraint is not. Rare earths exist in commercially viable deposits across the United States (Mountain Pass carbonatite), Australia, Vietnam, Brazil, and Madagascar[s]. Australia holds the fourth-largest reserves globally and hosts Lynas Rare Earths, the only significant non-Chinese heavy rare earth producer[s].
Processing capacity remains the bottleneck. Rare earth supply chain development timelines are substantial: mining projects average 15.5 years from discovery to production[s]. U.S. federal permitting averages 16 years[s]. Industry estimates suggest a decade minimum to build competitive non-Chinese capacity[s]. The United States remains 100% import-dependent for 12 critical mineralsRaw materials essential for economic security and national defense, often subject to supply chain vulnerabilities. and over 50% dependent for 28 others[s].
Recent policy responses include the October 2025 U.S.-Australia $8.5 billion framework for rare earth and critical mineral projects[s], EU Critical Raw Materials Act benchmarks (10% domestic extraction, 40% processing, 25% recycling by 2030)[s], and Japan’s recycling infrastructure investments since 2010. Environmental constraints complicate scale-up: producing one ton of rare earth elements generates approximately 2,000 tons of toxic waste[s].
Strategic Assessment
The rare earth supply chain monopoly differs structurally from other chokepointsCritical bottlenecks in manufacturing or supply chains where concentrated control or limited capacity creates dependencies that can disrupt entire industries.. Unlike ASML’s EUV lithographyA chip manufacturing technique using extreme ultraviolet light to etch transistors below 7nm. Only one company (ASML) makes the machines, making them a key export control target. machines (impossible to replicate in the near term), rare earth processing is theoretically contestable[s]. The barriers are financial, technological, and environmental rather than fundamental. However, the timeline for diversification exceeds the timeline for demand growth. Western economies face a multi-year window of acute vulnerability during which Beijing retains coercive leverage over green transition and defense supply chains.
