Huh!?! They (the Chinese Government) SURE CAN. If you are not aware of that, they can block the whole Internet in a matter of days, if they really have to do it. Sorry, but you are being too naive. While the government of the day (Hu-Wen) is the most liberal and open-minded in the past 50 years, it doesn't mean that the state is not capable of running in the New Authoritarian model. Actually, there has probably been a consensus among the ruling elite in Zhongnanhai since the post-Deng days that China will remain so for at least the next generation in order to secure a relatively more stable political and social environment for economic growth. Again, when it comes to China, the civil society is still too young to make a difference. Okay, class dismissed.
