> These actions may look anti-competitive, but these companies are all foreign. China does anti-competitive stuff to US companies . . .

I don't think there's any exception in the antitrust laws like "but you can be anti-competitive if the other guy did it first." And anti-competitive behavior in a Chinese company can hardly justify anti-competitiveness against a Japanese company or a Korean company. They may all be in Asia but they are nonetheless different countries. Google is also not a Chinese company, as you are probably aware.

Also a note: you don't have to be a monopoly to be charged with anti-competitive behavior. Being a monopoly can raise the standard of behavior and increase the penalties, but anti-competitive behavior can be illegal on its own, aside from whether you have an actual monopoly.
