Understanding the US-China Rare Earth Conflict
The global rare earth elements (REEs) market represents a $9.3 billion industry dominated by China's 85% control over processing capacity, despite the United States importing only $170 million annually. This paradox stems from China's strategic consolidation of separation technologies and solvent extraction capabilities since the 1990s, coupled with lax environmental regulations that reduced production costs by 30-40% compared to Western counterparts. While military applications consume just 9% of REE output, their irreplaceability in guidance systems like the F-35 fighter jet's AN/APG-81 AESA radar creates asymmetric vulnerabilities. The 2010 Dongfeng missile crisis, where China restricted exports to Japan during Senkaku Islands tensions, demonstrated REEs' weaponization potential, causing neodymium prices to spike 750% within three months. Current diversification efforts through Mountain Pass Mine's 15,000-ton annual output and Lynas Corporation's Malaysian processing plant remain constrained by China's export restrictions and 90% market share in permanent magnets.
