The west doesn't really do more than hand wrong China on the environment, and why should they? China is basically destroying their country so they can make cheap junk for the west! I mean, where else can they process rare earth elements so cheaply? Why China continues to do this at this point is a mystery, but the west isn't complaining much. Perhaps the CCP is afraid of moving to a consumer driven economy, people whose lifestyles are raised too much begin demanding political rights....
Honestly, if China wants to avoid complete environmental collapse, they'll have to drastically change their ways soon. You can say the west did it and survived, but the west didn't have 1.4 billion people doing it with the level of toxicity of a modern economy. The brink China is at now (and India is approaching) is unprecedented.
