Down to the Wire: TikTok at Center of Battle Between US and China Michelle Quinn SAN FRANCISCO - These are nail-biting days for the millions of people in the U.S. who useTikTok, the wildly popular video sharing app owned by a Chinese firm. The stakes are high. The U.S. government, citing national security concerns, has given the firm until Sept. 15 to sell itself or leave the country. ByteDance, the Chinese firm that ownsTikTok, is reportedly talking to several potential buyers including Microsoft and Walmart, which have joined forces to possibly make a bid, as well asOracle. And the Chinese government has changed its export rules about what parts of the firm's technology can beincluded inthe deal to exclude the app's powerful recommendation algorithm. Itpowers the "For You" feature in the app that suggests what short video a user would like to see next. Whatever happens, the imminent fate ofTikTokstands out as a key moment in the Trump administration's efforts to shield the U.S. from China's reach, observerssay. .
