While I agree with the fact that China has a lot of coal power plants, afaik they are the ones investing the most into new nuclear tech. And also it's not like their emissions happen on a vacuum; first the world outsources all of their factories to China, and then they complain that they pollute a lot, as though the demand for consumer goods was China's fault.

For a practical example, the government of the UK likes to claim that they are on track to be "zero emissions"[0] -- great effort on their part. However, here all the imported manufactured products that definitely are not "zero emissions" aren't counted. All these emissions were exported to China, and then they have the gall to complain that China's emissions are too high.
