TikTok Deal Complicated by Disagreement Over U.S. Ownership

A deal intended to address the Trump administration’s concerns about TikTok’s ties to China was complicated by a disagreement over whether a U.S. company would control the social media app and the president’s threat to block any agreement that leaves the service in the hands of a Chinese company. Mr. Trump had said he had given his “blessing” to a transaction that he said would result in non-Chinese investors, including Oracle and Walmart, owning TikTok.
