President Trump said China's Xi agreed to resume rare earth mineral exports to the U.S. after an April halt, marking progress in trade negotiations between the two countries.

China's critical-mineral export controls have become a focus on Trump's criticism of Beijing, which he says has violated the truce reached last month to roll back tariffs and trade restrictions.

Beijing has approved more export licenses for the critical minerals and magnets in recent days, but supplies remain scarce and factories in the West are running out.
