And what or who is stopping them from adopting the bitcoin(blockchain technology), bitcoin is obviously created in "that" way, for it to be beneficial to all, if only they will accept the technology, and also know that it would reduce the ease with which they perpetuate their corrupt practices.

Bitcoin isn't finding it's feet, this is a technology that is making waves, if China decides to stop it's citizens from trading bitcoin, I do not think it'll have that much adverse or lasting effect on it.
I'll be prepared to buy more coins during that period, as the whole furore would definitely see a temporary reduction in price, "buy on the news"
