China Rare Earth Export Controls: 70% Global Supply Under Strategic Restriction
China controls approximately 70% of global rare earth mining and 90% of processing capacity, increasingly weaponising export controls on critical minerals as geopolitical leverage.

Scope of Chinese rare earth dominance#
China produces approximately 70% of global rare earth minerals and processes over 90% into refined oxides, metals, and magnets. This dominance spans the full value chain from mining through permanent magnet manufacturing, with Chinese companies controlling majority capacity at each stage. The six major rare earth groups consolidated under government direction operate as strategic national assets with production quotas and export licensing. This market control over 17 elements critical to modern technology gives China unprecedented leverage over global manufacturing supply chains.
Export control escalation timeline#
China implemented export controls on gallium and germanium in August 2023, followed by antimony restrictions in late 2024, and rare earth processing technology export bans in early 2025. Each round has been calibrated as response to US semiconductor export controls, establishing a pattern of reciprocal technology denial. Export licence approval rates vary by destination country, effectively creating a tiered access system rewarding countries maintaining cooperative relationships with Beijing.
Impact on downstream manufacturing#
The defence industry faces acute vulnerability, with Chinese rare earth magnets used in guidance systems, jet engines, and communications equipment. EV manufacturers depend on neodymium-iron-boron magnets, with China supplying approximately 92% of global NdFeB production. Wind turbines require 600-800 kg of rare earth permanent magnets each. Consumer electronics, medical imaging, and industrial lasers all require rare earth components for which non-Chinese supply is currently insufficient.

Diversification efforts and alternative supply#
The US, Australia, and Canada have accelerated rare earth mining projects, but development from discovery to production typically takes 10-15 years. Lynas Rare Earths in Australia remains the largest non-Chinese producer but supplies less than 10% of global demand. Recycling contributes under 5% of supply. The processing bottleneck is even more severe, as establishing refining capacity requires specialised expertise that China has spent decades developing.
Business risk mitigation strategies#
Companies should conduct detailed supply chain mapping to identify direct and indirect exposure. Building strategic inventories of 6-12 months provides buffer against disruptions. Qualifying alternative material technologies reduces dependency but typically involves performance trade-offs. The most resilient strategy combines inventory building, supplier diversification, and product redesign to reduce rare earth intensity across the portfolio.
People also ask
How much of global rare earth supply does China control?
China produces approximately 70% of global rare earth minerals and processes over 90% into refined products, with dominant positions at every stage from mining through permanent magnet manufacturing.
What products use rare earth minerals from China?
Chinese rare earths are essential for EV motors, wind turbines, military guidance systems, MRI machines, smartphones, hard drives, and numerous products requiring permanent magnets, phosphors, or catalysts.
Can rare earths be sourced outside China?
Non-Chinese sources supply less than 30% of mining and under 10% of processing capacity. Diversification projects in Australia, US, and Canada are underway but require 10-15 years to reach meaningful scale.
