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.

News of the call came as new data showed U.S. goods imports dropped significantly in April as sweeping tariffs rolled out.

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.
