I disagree with you. China is all about
control and Bitcoin does not give them control over many aspects of their citizens. They want to control capital flowing in and out of China and
Bitcoin is borderless. They want to know what their citizens are spending their money on and
Bitcoin is pseudo anonymous.
Japan will soon rule the Crypto currency scene, because they have none of these restrictions and their government is embracing the technology.
Agreed Japan already does in some respects - legislation + guidance already in place
