thats like saying pan-white. most pan-nationalists arent that insane. theyre usually like pan-scandinavian or something. its possible to do it in a socialist way but there are also some really fucking weird ones like pan-turkism which would require the invasion of like 6 countries

china controls the area of all sinitic languages and tbh almost the entirety of the sino-tibetan group sans myanmar. outside of outliers like singapore and taiwan. though there are groups in both of those countries that wanna join china

the fact that china controls all of sinitic is kinda like an analogue of say, all of scandinavia uniting. or all the east slavic groups being together in the soviet union
