In a significant escalation of tensions in the trade war with the United States, China has announced a halt to its critical rare earth exports. This decision is seen as a direct response to recent tariffs imposed by the Trump administration and poses serious implications for U.S. industries, particularly in defense and technology sectors. With companies like Tesla, Lockheed Martin, and others reliant on these vital minerals, the move raises concerns about potential shortages and market disruptions. As China tightens its grip on rare earth supplies, experts warn of a looming crisis that could affect global supply chains and U.S. economic and defense capabilities.
