China's shipments of rare earth magnets to the United States jumped sharply in June. The rebound came after months of disruption and signaled renewed momentum in critical mineral trade between the two countries.

China’s exports of rare-earth magnets increased nearly threefold in June from the previous month, after the country lifted some export controls on the critical industrial inputs following a deal with the U.

China's Ministry of State Security says it is cracking down on alleged smuggling of rare earths materials that it says threaten national security.
