What I took from it was that China doesn't want its banks in the bitcoin economy right now, its too volatile. They aren't banning bitcoin, they just don't want their countries financial future to be linked to it. I can't blame them at this point, the swings are wild. Private citizens and corporations are free to buy, trade, sell bitcoin however. People and corporations are allowed to accept bitcoin as payment (except banks).
They're just trying to contain it so that the whole country doesn't go belly up when/if this great experiment crashes.
