There is an obvious reason why China don't like people's war against Gadafi. During last few months we have seen that public has thrown out many dictators who were ruling since 20 - 40 years. People want freedom and growth and this is the reason why all such dictators are getting annexed by Libya war. China don't have democracy hence people has no choice in China and this is the real fear in CCP that same thing could be repeated with them and this is the reason they don't like people's war against Gadafi. However it has least possibility but this is also true that public can do anything so CCP be careful.
