Chinese President Xi Jinping and U.S. President-elect Donald Trump held their first phone talks in four years Friday. According to Trump, he spoke with Xi about TikTok, just hours before the Supreme upheld a law set to ban the social media platform in the United States in less than 48 hours.

Donald Trump said he held a “very good” phone call with China’s President Xi Jinping, as the US-President elect prepares to return to the White House next week.
