I heard that both sides of the ongoing civil war ( https://en.wikipedia.org/wiki/Myanmar_civil_war_(2021%E2%80%... ) work with these criminal organizations to secure foreign revenue for weapons purchases - but that it is primarily a junta-driven thing. And that the people running them come from PRC Chinese organized crime (triads).
Well it's a sinosphere (insert one china joke) organized crime thing.
TLDR Taiwanese organized pioneered telco fraud 20 years ago, started third country scam call centers, primarily targetting tech illiterate PRC retirees. PRC/HK org crime saw how profitable, scaled up, ande more sophisticated (pig butcher + crypto to evade capital controls), targetted global Chinese diasphora. PRC cracks down domestically. They move to Myanmar / south eat asia, partner with local armed groups. Taiwanese call centers still around, but they're squeezed to other part of big butcher scacm chain, i.e. trafficking people. Anyway, every once in awhile their activities piss enough neighbours off especially PRC off that actual state power like junta has to intervenene.
