Why TikTok's security risks keep raising fears

TikTok is once again fending off claims that its Chinese parent company, ByteDance, would share user data from its popular video-sharing app with the Chinese government, or push propaganda and misinformation on its behalf.

China's Foreign Ministry on Wednesday accused the United States itself of spreading disinformation about TikTok's potential security risks following a report in the Wall Street Journal that the Committee on Foreign Investment in the U.S. - part of the Treasury Department - was threatening a U.S. ban on the app unless its Chinese owners divest their stake.
