U.S. President Donald Trump and Chinese leader Xi Jinping confronted weeks of brewing trade tensions and a battle over critical minerals in a rare leader-to-leader call on Thursday that left key issues to further talks.

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.

Trump said in his Truth Social post that the hour-and-a-half conversation phone call was “focused almost entirely on TRADE,” while the Chinese readout singled out Xi’s stern warning on Taiwan – the reddest of lines for Beijing – and the issue of Chinese student visas.
