ByteDance has stepped up efforts to separate its social media app TikTok from much of its Chinese operations, amid a U.S. national security panel's inquiry into the safety of the personal data it handles, people familiar with the matter said.

The Chinese technology company is seeking to provide assurances to the Committee on Foreign Investment in the United States (CFIUS) that personal data held by TikTok, which is widely popular with U.S. teenagers, is stored securely in the U.S. and will not be compromised by Chinese authorities, the sources said.
