No one said it was good. It is however better than, well, invading countries and getting a million people killed, training genocidal militia and getting a million people killed and the rest of the things France, Britain, the US and Russia have done. Some of them multiple times.
No country accepts Taiwan as independent. It'd be like, well, Georgia deciding to invade reintegrate South Ossetia; except of course that would be an invasion because we like Taiwan and don't like China- and Taiwan makes rather a lot of computer stuff we really don't want China getting their hands on.
In terms of actual invasions there's been one from China in the past 60 years which lasted six weeks and resulted in no occupation or similar. Which is just a tad better than those other countries mentioned.
Though neither of those examples are exactly great since there are more than a few examples of the west kidnapping people. As well as extrajudicially blowing them up. And invading their countries, and murdering their citizens, then imprisoning the people who blow the whistle on that behaviour rather than the perpetrators. All depends on how you couch the terms of reference.
When it comes right down to it most people only care about other people's governments when it effects them- or they're told to by the media. Hence, the use of 'internationally'. China's conduct towards certain ethnic minorities is without doubt genocide; though as we've continually seen recently genocide, torture, mass killing of protected classes like journalists and medics etc is not actually a bar to western support, if we like the perpetrator.
