Can we audit American corporations?
Also, who decides which entities are adversaries? I don't personally consider "China" my adversary. As an American who has to deal with US companies, many of them are far more antagonistic to me than a foreign country 10K km away. If "China" decides it doesn't like me, my life really isn't going to change much. If my electric company decides it doesn't like me, I'm in big trouble.
They're not an adversary in the same way that a guy demanding your wallet at knifepoint is, or a company able to cut off your electricity is.
China is an adversary in the sense that they're a totalitarian government, who, by the nature of that system, cannot brook any sort of opposition to their ideology, plans, or desires. All within the state, none without. That sort of system cannot exist in harmony with other systems for any extended length of time because doing so will suggest that the powers-that-be in China might not have all of the answers to the human condition. Either you fall in line, or you have to be eliminated.
If you're an American used to calling other Americans antagonistic, that's not going to work out well for you over the long run.
