You can’t even compare cities to cities, since even an entity like Beijing is structured and defined so differently from how we define a city like NYC or Chicago.
This is why I stressed the ethnocentrism of it all. It’s a country that has developed tremendously but not at all in the same way that we have traditionally defined development in the western sense, and a lot of that comes from its size, its historic dynastic cultures and their political structures, and its population (count and local densities).
I haven't ever heard of the Chinese government claiming China to be a developed country - that was one of the original contentions above. I also think that by any reasonable metric, China is a developing country. There are pockets that are much more developed than others, but the country as a whole is still very far behind developed countries.
That's not what I'd call "reasonable." You have to normalize by population.
