If you live outside the three supported countries, you don't have to be permanently switched to them to use News on macOS. You only need to switch once, create an alias for the now revealed News app and then switch back. It will continue working (and as far as my testing went, it also syncs with iCloud).
You can also use my alias (if it's not portable across computers, I apologize). Just put it in your Applications folder (and/or wherever you see fit).
