If no one else wants to burn coal, coal will be cheap. It's not that expensive to dig it out of the ground and transport, and most of China's coal is mined in China.
Any solution that doesn't involve everyone agreeing to care about the externalities of coal (air pollution and greenhouse gases) will result in someone continuing to burn a lot of coal.
