China is ahead of the US, behind the EU and many other (Western and non-Western) countries (with almost no country or bloc is on track to reach the Paris agreement targets). These are simple facts. As the world's largest polluter, China should do much more than it does, but it seems there is not even a willingness to do so.
I won't comment on your accusation of being biased. I am not long here on Lemmy, but the reaction here if and when you criticize China is often weird. It's certainly not all, but some people appear to be personally insulted if you just say something critical of this regime. That's often not a sane reaction.
