This is nominally the correct answer. The key fault that lied with the Communists of the former socialist Afghanistan they fell into ultra-left deviation of moving too far ahead of the Afghan people and attempted to force their people to move faster than they were willing from afar, leading to their masses becoming fertile grounds for reactionary religious fundamentalist sentiments to sprout and causing an unbroken vicious cycle of violent reprisals that would lead to the fall of Socialist Afghanistan and the weakening of the Soviet Union.

Material improvements are indeed one of the primary means of countering festering reactionary seeds, but the methods of application of ideology is another one as well. And currently I'm of the belief that China's currently pursuing, as far as we can generally see thus far, the correct course in relation to their own self-governance. Nevertheless I do hope they're paying close attention and have been working thoroughly to ensure the defenses of their western regions.
