I noticed this too. China, by many of its aspects, didn't feel like a developing country while I was there. People were actually doing their job instead of cheating each other all the time. The Netherlands is fine but as far as I see (and unfortunately we see since English is the global language) the UK and USA are filled with scammers and "get rich quick" type of people nowadays.
Well, its not a developing country to begin with, its a Soviet style economy that avoided the institutional mistakes of the USSR and because of that later thrived.
There is no major commonality in neither cultural history, industry, economy nor education systems between China and any developing country. Eastern Europe or possibly Japan are the direct comparisons if one must be made.
So its not that surprising that it looks completely different, because that's what it tend to look when you look at 2 vastly different objects side by side.
