Neuroi one could be, I mean it's clear that under Chinese Culture Witches would not be able to prosper as much (Which why in the map their witch data is so low), so they would have TONS of problems dealing with Neuroi.
A Remanant of Imperial China is also a good possibility too, same for the other since the official map has no name for the territoy leaving it open for being either a of these possibilities.
It couldn't be comunist china thought, comunism doesn't exist in the SW universe and I can see why, it wouldn't be needed as it'd be a very "Anti Witch" ideology, not mas much as Abrahamic religions, but they definetely wouldn't like depending on little girls to defend themselves from Neuroi.
Thanks for the suggestions, I think I'd go with either the second or third one when I redisign the map
