Not easy to do so, it will take quite some time before China can abandon coal. More than 50% of Chinas power generation is through thermal power plants.
The only alternatives is renewable/nuclear both having its own drawbacks.
I think it will be slowly replaced in the main cities just to improve on air pollution. The likely replacements will be natural gas and nuclear where hydropower isn't available. China could never fully replace coal with nuclear unless they had a closed fuel cycle. Without that they would need to import a lot of uranium which would be yet another problem. Well, China is working on that though. They have a program for building fast reactors and fuel reprocessing plants.
