When China won the right to hold the Olympics, they heralded it as the event that would show China was becoming more tolerant, more open minded, more democratic and essentially less censored.
China that "unblocked" websites in the run up to the Olympics as evidential proof that their promises to the IOC were being kept.
However, less than five months later, the Chinese government are again blocking foreign websites for fear that they may report on the 20th anniversary of the Tiananmen square massacre when thousands of Chinese students and protesters were machine gunned to death in a Nazi style killing orgy by the Chinese Army in 1990. Needless to say, the Chinese government want no details of this or the burning of the bodies being mentioned to their population.
So now we know that China's promise to the IOC was a hollow lie. Welcome to China. Land of the repressed.
