The only racism is from characters specifically said to be racist. And they never say China is number 1. China has a lead due to that being where seer started the game. Plus later we see that they have a slight edge in genes but it's not so massive that it matters.The only people who are shown to be superior is anyone who has been trained in the "game". Since the alien civilization has had billions of years to develop vastly superior tech and cultivation material compared to anything on earth.Plus every country we see shows patriotism. We even see why they show so much patriotism since most of the people who are showing it are military people or politicians.The players show "patriotism" in that they like to say their country is the best but that's also done in games and is just being reflected here. Most of the players don't actually care about their country and just care about the game. They just mess with other country's players for fun.
