It would take time to wind down the company, i.e., sell the Chinese stake to some guppie in the U.S., just before it crashed and burned because the teenies would take it out on the new entity. By the time the alleged president could get his revenge on the teenies and deprive Xinping of valuable windows on their adolescent angst, Biden would have a chance to change the rules. At this point, it probably isn't a burning item on his agenda. He's more concerned with stopping the appalling damage to the country,

That assumes a decision made based on practical logic.

It's a bit late if the business is sold to a US company in a fire sale at a low price. How does a later administration unwind that?
