WASHINGTON (AP) — U.S. President Donald Trump said he would meet Chinese leader Xi Jinping at a regional summit taking place at the end of October in South Korea and will visit China in the “early part of next year,” following a lengthy phone call between the two Friday.

In a Truth Social post, Trump said Xi would come to the United States “at an appropriate time” and that they had made progress on “the approval of the TikTok Deal” to allow the popular social media app to keep operating in the U.S.

A statement from the Chinese government did not mention the visits, nor did it offer clarity on what Xi had agreed to regarding a sale of a controlling stake by TikTok’s Chinese parent company to avoid a U.S. ban. But Xi told Trump to avoid imposing trade restrictions to keep trade ties from getting worse.

While the highly anticipated call suggested a cordial relationship between the leaders of the world’s two largest economies, their statements showed the challenges facing two countries with conflicting worldviews.
