I don't think this is a factor , mining of the bitcoin is a necessary need of bitcoin life because if bitcoin will not be mine then surely there is no chance for the transaction to run in the bloclchain system .
And also if the miners are mining in more amount then we should see towards the factor that bitcoin's transaction will become more faster then with what we have confirmation speed in lack of miners .
And another thing that is the demand of the bitcoin , if demand of the bitcoin is high then surely price will grow according to that and if not then surely it will not increase and will remain at constant or will drop step by step .
So we should it target China for such things , but surely price sometimes depends upon the Rumours that we heard many times from Chian .
