We heard it before. This is just going to be on the paper. China is pro-business, if they can get money out of it they will make money out of it including mining. As long as miners pay their energy bills, they will have no problem with it.

China's government may hate BTC for they can't control it, but if they announce they are going to ban BTC another country will take advantage of it and will start accepting. BTC is rare. The Chinese government knew they can use BTC as their wealth. They may even be buying the fresh BTC from the miners.
