A lot of China fearmongering (in general, not you in particular) is just xenophobia. You will see the argument that the US has to do imperialism because if it doesn't, then China will become dominant and do the exact same sins. It's also a bit of a self-report: we tend to assume other people will act like us if given the chance so any accusation is really a confession.
