Thailand has cut electricity, internet and fuel supplies to five border areas in Myanmar, a senior Thai minister said on Wednesday, as the Southeast Asian nation steps up efforts to choke scam centres that have become a growing security concern.

Thailand on Wednesday cut off power supplies to areas in Myanmar where scam networks operate, following a public outcry demanding government action to tackle the problem

The power cut at 9 a.m. local time affects Myanmar’s Payathonzu in Mon state, Ban Muang Daeng and the Thai-Myanmar Friendship Bridge in Tachileik, Shan state, and the eastern town of Myawaddy in Kayin state, he said.

Thailand will suspend electricity supply to some border areas with Myanmar in an effort to curb scam centres, its government said on Tuesday, amid growing pressure on the illegal compounds that have ensnared vast numbers of people of multiple nationalities.

The measures were announced on the eve of PM Paetongtarn Shinawatra’s state visit to China, during which she is set to discuss anti-scam efforts with Xi Jinping.
