Actually i think you need to update this as it is not true (unless you are after sensationalism) - the Central Govt in China has told the regional areas (who like to pad their GDP numbers to look more successful) to properly regulate BTC miners in their provinces instead of giving them deals for free/cheap power - it is not an overall crackdown on mining - nor will it affect any of the large miners - it is all the small ones who popup in a region.
