If it is that important that there should be favourable Sino US relations, then why is it not there? Why is China wanting everything to go her way? True that they have historically been able to convert people to become Hans, but why should Americans also become Hans? What is so great about being a Han? Instead of their desire that the US should not step on Chinese corns, the Chinese should stop stepping on the US' toes and the world's toes. They are not talking to 'barbarians' as they used to think of everyone who was not Hans. In fact, the action of the Chinese indicate that they are barbarians and not the world, if one goes by the genocide they are practising in Tibet and against Uighurs!
