What is the rare earth supply chain and why does China dominate it?

About rare-earths

Direct answer

The rare earth supply chain is a multi-stage industrial process spanning mining, separation, refining, and manufacturing of 17 critical elements, and China dominates every stage — controlling approximately 60% of global mining output, 85-90% of global refining/separation capacity, and over 90% of permanent magnet production. China's dominance stems from decades of deliberate state investment beginning in the 1980s under Deng Xiaoping, who famously declared 'the Middle East has oil, China has rare earths.' Low-cost labor, lax early environmental regulations, and massive state subsidies allowed China to undercut global competitors and force closures of Western processing facilities. Today, even ore mined outside China — in Australia, the U.S., or Africa — is largely shipped to China for processing, making the entire supply chain structurally dependent on Chinese industrial infrastructure.

Key Takeaways

  • China controls ~60% of rare earth mining, ~85-90% of separation/refining, and ~90%+ of NdFeB permanent magnet production — dominance spans the entire value chain, not just mining
  • The 17 rare earth elements (REEs) include critical materials like neodymium, dysprosium, terbium, and lanthanum used in EV motors, wind turbines, defense systems, and consumer electronics
  • MP Materials (MP) operates the only active rare earth mine in the U.S. (Mountain Pass, California) but historically shipped concentrate to China for processing — it is now building domestic separation capacity
  • Lynas Rare Earths (LYC.AX) is the largest rare earth producer outside China, mining in Australia and processing in Malaysia, representing the most significant non-Chinese separation operation globally
  • China has demonstrated willingness to weaponize REE supply chains — it imposed export restrictions on Japan in 2010 following a territorial dispute, cutting shipments by ~40%, and announced new export controls on gallium and germanium in 2023
  • Western governments are investing heavily in supply chain diversification: the U.S. DoD has awarded hundreds of millions in contracts to MP Materials and others; the EU Critical Raw Materials Act targets 40% domestic processing by 2030
  • Processing rare earths is technically complex and environmentally intensive — separation requires hundreds of solvent extraction steps, creating significant barriers to entry that protect China's incumbency advantage
  • Defense dependency is acute: U.S. F-35 fighters, Tomahawk missiles, and Virginia-class submarines all require rare earth permanent magnets, making supply chain security a national security priority

Evidence & Analysis

  • China produced approximately 210,000 metric tons of rare earth oxides in 2023 out of a global total of ~350,000 metric tons — roughly 60% of global mine supply (USGS 2024 Mineral Commodity Summaries)
  • China's share of global rare earth separation/processing capacity is estimated at 85-90%, meaning most non-Chinese ore must still enter Chinese processing infrastructure
  • Deng Xiaoping's 1992 statement 'The Middle East has oil; China has rare earths' laid the ideological foundation for China's 40-year strategic accumulation of the sector
  • China flooded global markets with cheap rare earths in the 1990s-2000s, causing the closure of Mountain Pass in 2002 and effectively eliminating Western processing competition
  • In July 2023, China announced export licensing controls on gallium and germanium — related critical minerals — demonstrating continued use of mineral supply as geopolitical leverage
  • The U.S. Department of Defense obligated over $439 million between 2020-2023 to domestic rare earth and critical mineral projects to build resilient supply chains per DoD annual reports

Key Companies
