The United States is intensifying efforts to reduce its dependence on China for critical minerals, particularly lithium and rare earth elements essential for electric vehicles (EVs), defense, and technology manufacturing. Currently, China controls about 70% of U.S. imports of rare earths and dominates approximately 70% of global rare earth mining and 90% of processing. Beijing has imposed export restrictions on strategic minerals such as samarium, terbium, and dysprosium, which are vital for EVs and defense applications, despite a 90-day tariff truce.
In response, U.S. companies Exxon, Occidental, and Equinor are piloting direct lithium extraction (DLE) technology in Arkansas to tap underground brines, a method compared to the shale oil revolution. Meanwhile, Australian firm Lynas Rare Earths has achieved a milestone by producing dysprosium oxide, a heavy rare earth element, outside China, enhancing supply chain diversification. The geopolitical tensions over mineral supply chains have prompted countries including the U.S., Brazil, and European nations to boost mining and processing capacities domestically and abroad. China has pledged to revoke some export curbs as part of a recent trade truce, signaling potential easing of restrictions. However, global firms continue to face challenges securing these critical minerals amid ongoing export controls and geopolitical competition.
