The TikTok law kicks off a new showdown between Beijing and Washington. What's coming next?

TikTok is gearing up for a legal fight against a U.S. law that would force the social media platform to break ties with its China-based parent company or face a ban. A battle in the courts will almost certainly be backed by Chinese authorities as the bitter U.S.-China rivalry threatens the future of a wildly popular way for young Americans to connect online. Beijing has signaled TikTok should fight what it has called a “robbers” act by U.S. lawmakers “to snatch from others all the good things that they have.” But should a legal challenge fail, observers say Chinese authorities are unlikely to allow a sale, a move that could be seen as surrendering to Washington.
