China's population is not homogeneous, and neither is Singapore's. Singapore has large Indian and Malay ethnic populations, China's got dozens of ethnicities and the main Han ethnic group is really a mix of different cultural and ethnic groups where the best analogy is how "White" people in the US are treated as the same ethnic group despite originating from dozens of European countries. No population is truly homogeneous. The trick is putting together the right social and economic incentives so you can brush over the ethnic differences. To get to a point where people think of ethnic differences as less dividing them into tribes in a battle royale where only one can survive, and more as different opinions on the best flavor of ice cream.
