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 300 Chinese scam centre workers to be repatriated through Thailand on Friday, as authorities intensify a crackdown on the illegal operations. Myanmar's junta said in a statement that a second group of 300 Chinese nationals was handed over on Friday via the Thailand-Myanmar Friendship Bridge 2 at the Thai border town of Mae Sot.
