I’m not 100 percent sure. All I know is that now the area is called Xinjiang, so if this map is from the future, why would it be called sinkiang? Even if it’s a correct name from the past it wouldn’t make sense to use it for the future unless your only source of geography is hoi4

Sinkiang too instead of Xinjiang. I like the game but my god, it is not a completely accurate source for any information pertaining to the non western countries at all, far from it in fact.
