Seems like you just had a bad dream, and you're being paranoid about China, first of all China just can't close its Internet cables, how will they do hacking, and cyber attacks, in the age of digitalization no country can afford to be without net cables and if it's any news to you, there is just a fresh update coming that China is planning to regularise Bitcoins. So no banning on the net.
