Private sector is made up of people; people like you and I in fact.
In China, the larger your "private" company is, the more direct and overt interference you will end up with from the PRC government. They don't infiltrate businesses in subtle/clever ways like in the West, or outright strongarm you like in a despotic Middle Eastern regime. It's the law in China that enterprises of set sizes are subject to progressive levels of hands-on, close government supervision, sort of like an honest form of despotism.
In relation to the Chinese Bitcoin industry, make of that what you will.
