@Rezcore I'm not also up-to-date, but from what I gathered, apparently it all started with K-Pop fans from Malaysia clashing with Koreans because of concert stuff? Then Koreans retaliated by pointing out their superiority over Southeast Asians.
Then, having dragged the entire SEA region, Flips, Malays, Indos, Viets, Thais, Burmese, Lao, Cambodians, Singaporeans, Timorese and Bruneians united against a common enemy.
It kept on escalating, and eventually, the Chinese, Japanese, Indians, Pakistanis, Poles, and some other African states were dragged and sided with SEA countries.
