The Chinese authorities have given deadlines for the rest of the mines until 30.09.2017 but this is a Chinese policy itself where there have been cases similar to this.
A broader clampdown will likely include blocking mainland access to websites of foreign bitcoin exchanges such as Coinbase in the U.S. and Bitfinex in Hong Kong.
This concurs with a document which surfaced last week detailing how the Chinese government will try to block access to bitcoin exchanges and other important services that reside outside of the country. While the document is unverified, Sinaclaimed that it is authentic.
But my idea is that china will not block bitcoin because there are some kind of attempts in the past I think they will postpone this decision for another year
