As right now China is thinking of creating their own coin, so it means that they wont stop mining but they can regulate it and make more strict restriction so that illegal usage of power in mining wont work
The title says bitcoin mining so it only includes the mining of bitcoins. Mining anything else there is no law against or anything. Yes, the illegal use was not really illegal it was more of taking advantage of a situation that was never meant to work if people require such high amounts of power. Keeping things normal is fine so that is why that worked for a long time. I am surprised they were able to mine as much as they were for so long without anything being done.
