China's exports of rare earth magnets to the United States in June soared to more than seven times their May level, marking a sharp recovery in the flow of critical minerals used in electric vehicles and wind turbines after a Sino-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.

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.
