Chinese exchanges are already losing their significance, but if this continues, then you can bet on it that people will look for other ways of obtaining Bitcoin. P2P is still in its early stage in China, but if regulations will force Chinese exchanges to tighten their policies to more extreme levels, then it will only push people away from them, where they will give the P2P market a massive boost. One thing I am happy with, is that all these regulations won't harm the price of Bitcoin anymore. China sinks, Japan is about to break through.
