China's Olympics

I support the positions taken by some celebrities (Spielberg, Clooney) regarding the connection between China's policy towards Darfur and the Olympics. But isn't the real issue China's policy towards China? Surely whatever harm the Chinese government is doing by propping up the bad guys in Sudan is trivial compared to their own totalitarian policies at home that affect 1.3 billion people. Let's protest China policy in Africa, but don't forget Chinese policy in China.
