In a significant escalation of the US-China trade war, China has suspended exports of critical rare earth minerals essential for various industries including technology, automotive, and defense. This decision threatens global manufacturing and security operations as countries scramble for alternative suppliers. China produces nearly 90% of the world's rare earths, which are vital for electric vehicles, smartphones, and military hardware. With many Chinese ports halting shipments, the move could severely impact US military contractors and tech manufacturers, raising concerns over supply chain disruptions.
