President-elect Donald Trump said on Friday he spoke to China's President Xi Jinping about TikTok and other issues as he prepares to take office in a matter of days.

       Trump confirmed the call in a post on his social media platform, calling it a "good one" for both nations.

       "It is my expectation that we will solve many problems together, and starting immediately," Trump said. "We discussed balancing Trade, Fentanyl, TikTok, and many other subjects. President Xi and I will do everything possible to make the World more peaceful and safe!"

       The call came just before the U.S. Supreme Court upheld a bipartisan law that could see TikTok banned in the U.S. after Jan. 19 unless its Chinese-owned parent company sells the widely popular app.

       The Biden administration doesn't plan to take action to immediately force TikTok go dark, ABC News has reported, instead leaving it to the incoming Trump administration to implement.

       Trump, who tried to ban TikTok in his first term, has now promised to save it. He met with TikTok CEO Shou Chew at his Mar-a-Lago club in December, and Chew plans to attend Trump's inauguration, sources told ABC News.

       In addition, Trump had extended an invitation to Xi to attend Monday's ceremony in Washington. Though experts noted it was unlikely Xi would attend.

       But Xi's special representative, Vice President Han Zheng, will attend, a Chinese Foreign Ministry spokesperson announced Friday.

       "We stand ready to work with the new U.S. government to enhance dialogue and communication, properly manage differences, expand mutually beneficial cooperation, jointly pursue a stable, healthy and sustainable China-U.S. relationship and find the right way for the two countries to get along with each other," the spokesperson added.
