For Chinese aims to be "Nazis", it's got to be pretty extravagant. Here's what I'd go with:
- Getting HK, Macao, and Taiwan back. They are populated by Chinese, they should be ours!
- Getting the old Qing borders back. Self-explanatory; what are those damned Russkies doing all the way over here? Go back to whence you came!
- Conquering Korea. Sure Korea was never actually ruled by China, but now it will be.
- Taking Vietnam. See Korea. Also if it's ruled by France, that's a major no-no.
- Thailand: Maybe we can co-opt them. If not, our army will.
- Malaysia/Singapore: Another Western colony? It'll be ours soon.
- Pacifying Japan: No point in ruling over those dwarfs, but they have to recognize our power. Let's go and bomb them into the stone age.
- Philippines: Maybe, if we've got time and forces to spare.
- Indonesia: Ditto Philippines.
- Tibet: Duh, almost forgot.
