> I can't remember a covert operation done by China

Why would you expect to? Have you been watching for them? Are you privy to information the rest of us don't have? They are covert after all. "I don't remember" says more about your perception than about the underlying reality. As others have pointed out, there are many known instances of Chinese malfeasance, mostly around misappropriation of military secrets. There are surely some unknown as well.

Again, more to do with your perception than the underlying reality. That those are the first explanations you grasp for says nothing about whether they're the right ones.
