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.

Total cargoes of the magnets rose to 3,188 tons last month, according to Chinese data on Sunday, more than double volumes of 1,238 tons in May in the midst of China’s curbs.

It is an opportunity to build domestic capacity, strike deals with other countries and address dependency in its green energy transition.
