Unlike the USA? So if China came along bombing the shit out of mexico, you'd expect the US to sit on their hands?

> They've also annexed Tibet

Annexed is hardly the right word. Tibet was part of China for centuries, they regained power after a brief period of independence. It's well within reasonable to disapprove of that, but putting it like China just conquered that totally different country that it had no relations with before is just wrong.

Same with Taiwan. To China it's a province where the government has been taken over by separatists, so why should they just give it up? Western media conveniently never mentions this so again in the minds of people Taiwan is just this country that has existed forever and is now attacked by the evil Chinese. Just pull up a list of countries which do and don't regard Taiwan as its own sovereign country and not part of China.
