I am neither Chinese nor American, but I fly on both Chinese and American airlines quite often...both to and from China and America. So I have no axe to grind. Airlines from both countries, and governmental agencies from both countries have, and are entitled to have their own rules and processes. Please be assured, from the point of view of someone who is objective, that on the whole they operate sane and sensible rules and processes. But both have strange and bizarre obsessions that you just have to embrace, because they are simply not going to change. You might not like them, but if you get crazy about them, you are the only one who’s going to feel bad.
