Not really. That implies that a) there's some kind of objective end state for a country and b) they've reached it.
I definitely don't think "western" was the right term for it.
Another chilling moment when I realise that I'm way too old and can perceive slow changes of things (like the meanings of words). Please don't do that.
I highly doubt you are old enough that western did not always have that meaning for the majority of your life. It's a holdover from the Cold War, after all.
