Cambodia probably.

Singapore is a poor country, very third world

Myanmar

Laos

No idea (probably Cambodia), but Thailand is literally the best.

Are you a Thai, or a Eurorapist?

I don't have much knowledge of the region, but probably Indonesia.

If Papua New Guinea was counted, that would be my choice.
