US President Donald Trump said Chinese leader Xi Jinping has agreed to restart the flow of crucial rare earth materials, after announcing a new round of US-China trade talks will be held in London on Monday.

Mr. Trump said in a post on Truth Social that his call with Xi Jinping, China’s top leader, had focused entirely on the trade relationship between the nations, which has soured in recent months in a dispute over the export of critical minerals used in an array of industries.

The rare leader-to-leader call confronted weeks of brewing trade tensions and a battle over critical minerals but left key issues to further talks.
