What?!?! Either explain or apologize.
What is China's relations with these Middle east regimes and terrorist organizations?
Take Iran for one example. That regime is the largest granddaddy of all terrorist sponsoring regimes and spearheaded the modern Islamicist movement.
The communist regime in China has close tie to the Iranian Islamicist regime. Rather than being concerned that they are supporting Xinjiang rebels, the communist regime has been overly freindly with the Iranian regime. They have cooperated in terms of weapons development and nuclear development.
Shortly after Bush's "Axis of Evil" speech the Communist Pary General Secretary Jiang Zemin held a summit metting in Iran pledging further cooperation and alliance.
This is but one example. Your analysis is being presented by some but there is no actual basis for it given the closeness of the Chinese regime with terrorist sponsoring states.
