Singapore is a tiny bubble that if you are rich you can live a luxurious life style without fearing (too much) for your safety but I would not call it western by any means.
It is a tiny city, but it has a massive role in Southeast Asia. I have lived there before and lived a great life without being rich by US or Singapore standards. The national language is English. They are by all means a capitalist country. It is a modern high tech society. Very western if you ask me.
The only way they aren’t that I can think of is that they are not a democracy.
