What is the moral values of nations?(China, for example)

I had a question about the moral values of nations, what are they really?

When I’m thinking of what the high level values of a state are such as China, I always assume that they want to make their populous as happy as possible. I don’t really think this is the case but what is then the truth in reality?

I’m uncertain about the answer but also what questions to ask, if anyone has any thoughts please let me know! Some questions I’ve thought of are the following: What do you think the average Chinese politician values morally?
How do you find out what the average Chinese politician values? What is the incentive structure for politicians?

The question of how individual moral values affect divergence from the incentive system is particularly interesting to me as this can help predict the effect of placing a system in one country compared to another among other things. (how would an average person in China use a totalitarian state compared to an average person in Indonesia?)
