I'd be criticizing western countries if this article had been about the western world - but it's not, so that's not really relevant commentary. If I showed up to say something like "why aren't western countries doing better" it would be a valid point, but would absolutely not address the issue - that china is in no uncertain terms absolutely failing the environment. Trying to deflect that with accusations of racism is... transparent, at very least because you have yet to address the criticism but only the form my argument takes.
Why are you so biased that you can't even accept criticism of a group you support might be legitimate in an article explicitly about the actions of said group? People from the US do that all the time, what makes China special?
