myanmar has had an ongoing civil war for decades so location is moot. there is no central authority that has the ability to deal with these things. the scam centres can get a lot of freedom just by supplying tinned food and petrol to whichever group they are closest to.
https://www.aljazeera.com/news/2015/4/4/hundreds-of-enslaved... one thing that is still happening is fishing fleets buy myanmar people and keep them as slaves on trawlers or in remote island prison camps
there are 100+ formal languages in Myanmar, at least 100 unique ethnic groups, and over 150 armed combat groups. and the ethnic diversity is very abrupt, people living 30km away from each other can be so different they can't communicate with each other at all. foreign governments have almost zero influence on the ground

because the languages are so complex and dialect driven, they are often impossible to translate and monitor too.
Aeon[1] just published a piece on the topic. It discusses the victim versus villain aspect.
Having read that, it seems that the only remedy would be a Chinese government intervention (as it seems to be Chinese criminal gangs that run these facilities). That intervention might be triggered by the international image lose for the government in being associated with these scams.
