No, but they expect to be able to do it in the short term. I think at this point they are just hoping to delay a more open internet for five or seven years -- much beyond that begins to seem laughable.
I suspect the leaders of China understand better than we do just how tenuous their control is, and I think their fear of free political speech is legitimate. A protest in Tiananmen Square once almost brought down the government, and I don't think the CCP could withstand another protest of that magnitude, though of course less-lethal crowd dispersal technology has come a long way.
