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.

President Donald Trump said his Chinese counterpart Xi Jinping had agreed to restart the flow of rare-earth materials, as negotiators from the two nations prepare to resume trade talks on June 9 in London.

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.
