China has actually been leading the charge in terms of green energy lately, at least in terms of making solar power equipment more accessible by way of driving down cost.

I have no idea however if they're just exporting this to other countries or if they're also pushing renewable energy domestically.

From what little I've read on this topic in recent years though they seem to realize that all of that smog is coming from somewhere and are taking meaningful action to remedy it, which is in stark contrast to what we're doing in the states these days with stifling clean energy and promoting coal.
