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.

July 7 (Reuters) - China's export restrictions on rare earths brought parts of the global auto supply chain to a halt and U.S. President Donald Trump to the negotiating table. But at home, they're a big headache for companies already struggling with a slow economy.

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.
