Not for long china can controlling bitcoin price, im sure now they on trouble due their efforts to make the price under $ 1000 always can not last long and now all trader are smart they not easy get in on the trap.
Honestly I used to believe that China is trying to control the price when Bitcoin price go up more than $1000 but the last two press release of PBOC does not mean that they are or in a position of wanting to control Bitcoin price. They are just after the implementation of the law regarding money laundering and possible support to the terrorist activities. There is no way in their announcement that they are banning or want to control bitcoin price. they are just preparing their exchanges for a more legal way of implementing rules on the transactions of Bitcoin.
It is true that they are not controlling it directly but since the majority of the miners are located in china since mining is profitable there because of how cheap electricity is makes them the ones that affect the price in some way like if they try to make strict laws about bitcoin transactions there means they want to come back more stronger than before.
