Superiority complex is a westerner thing (eg. Semite, aryan, American white). Chinese historically has no notion of racial superiority like Nazi Germany or even Imperial Japanese. They don't even consider blood purity like Japanese. Their cultural norms is to preserve what they own. Like HK, Macao, Tibet and Taiwan. They will take decades or centuries to get it back because that is what they own even if it is millenia ago. The closest this idea would be Israel...but unlike them Chinese dont view it as God-given. It is more like it is because it is as nature dictate. China and Russia wont be allies for long because of difference in races. But as long it serves their immediate purpose they will do so. Read up how Jin fall to Mongol because the sourthern Song want to appease the Mongol. In the end they fall too. The northern also killed their best general because that can buy appeasement with Mongols. Chinese historically is like that all in tactically but very short-sighted when it comes to long-term strategy.
