I don't think so, bitcoin is growing up and if in mining you mean there are some companies outside of china that mining bitcoin. 
you might right,but leets see how china take control on some exchange,and big farm on china have biggest bitcoin mining,we can't deny that china have better power consumption and can handle any problem related miner,and also their exchange have better price than coinbase or itbit. No doubt that China have some big whales and manipulators. They are the one who is starting the price rally starting from their exchanges. If succeeds it will now be dragged to other exchanges and the result? Price rally.
China is always been greedy when it comes to something that they can get profit. Like reverse engineering of original products. And now they are trying to manipulate bitcoin with by their mining power.
Because most of miners are they.
