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.

The quotas are closely monitored as a barometer for the global supply of rare earths, a group of 17 elements used in electric vehicles, wind turbines, robots and missiles. China is the world's largest producer of the minerals and the government typically issues them twice a year to state-owned companies but they have been delayed this year.

Despite a detente on China’s restrictions on the critical manufacturing inputs, shipments remain far below last year’s levels.
