President Trump and Chinese President Xi Jinping haven't spoken since before Mr. Trump took office, but Trump administration officials say a call between the two leaders could happen as soon as this week to discuss the ongoing trade war.

President Donald Trump is using his love of tariffs to threaten high-profile American companies. Over the past month, Trump has said he’d like to target two specific and very different companies – Apple and Mattel – with tariffs aimed at their key products over comments by their CEOs.
