Efforts to shut down online scam centers in Myanmar appeared to gain momentum on Monday as a top Chinese security official visited both sides of the Thai-Myanmar border.

A group of 200 Chinese nationals plucked from scam centres in Myanmar crossed into Thailand and were flown home on Thursday, as part of a multinational effort to repatriate hundreds caught up in massive internet fraud schemes,

Myanmar handed over more than 100 Chinese scam centre workers to be repatriated through Thailand on Saturday, the third batch in a major crackdown on the illegal operations.
