Miners will go where the big bucks are. Plain and simple. Or put it simpler, hash rate will go where the big bucks are, irrespective of the actual Chinese miners.
The "big bucks" are in China (another plain and simple point you seem to have missed).
How did BTC ever get to over 1000 USD - China - how has BTC suddenly jumped up in value recently - again China - you seem to really have a trouble with China.
Don't like Chinese people?
