China is actually quite environment savvy. They understand that environmentally friendly tech is an economic growth machine. The US less so. I do t worry about China as much as I worry about US.
But overall, my impression is that disregard for the environment is rampant: - 60% of the country's rivers suffer from pollution to such an extent that they cannot be safely used as drinking water sources https://en.wikipedia.org/wiki/Water_resources_of_China - https://www.theguardian.com/cities/2017/mar/24/river-rubbish... - http://www.businessinsider.de/china-factories-shut-down-to-c...
As is it stands now, it is a pretty disgusting place to live in and these habits need a lot of time to be fixed (just because government announced they care environment, it doesn't mean that people/businesses will suddenly start caring as well). However, as you say - they are at least on the right direction for the change.
