Can you imagine what would happen to the global economy if the 2008 Olympics were boycotted?
The Chinese could instantly cease all trade agreements with the nations that boycott the games. I really do not think they would give a rancid rodents rectum about any perceived economic impacts, they've already got what they really wanted, the technology and the means to use it. They've been an isolationist country for so many years it really wouldn't bother them in the slightest to slam those doors shut again. The rest of the world however has invested so much money getting into China that it would have a devastating impact on their economies. In short, it really does not matter how the rest of the people of the world feel about it, nothing is going to happen.
