China has already indicated that because the sale would require a "technology export" of the algorithm, it would need their approval. And also that they would not approve it.

So if China has already made it clear it considers a TikTok sale illegal, this is a ban.

That being said, you don't get Nancy Pelosi and Marjorie Taylor Greene on the same side unless there is some serious fire behind all of the smoke. My guess is everyone who has seen the classified info agrees this ban is too critical to even play games with it.
