Vietnam is a SEA country, but the govt is communist and very similar to China. There is a reason why it's called the mini-China. Anti-korean sentiment are rising in Vietnam after many years of koreans treating them as garbage. Especially the foreign bride situation. Also, lately many korean events involving Kpop idols and celebrities are boycotted by domestic artists because of unfairness and treatment. VPOP biggest star, Son Tung M-TP would rather work with american stars like Snopp Dogg than Kpop groups. He has videos with over 100-200 million views and he avoids any korean events, even after many invitations. Vpop, their music industry is booming and they would rather support their own than foreigners. If Vietnam bans Kpop, it could be a domino effect in the rest of SEA. Kpop never cared about SEA frankly. So for them, it's probably no loss right?
