An airlift carrying more than 1,000 Chinese nationals who had worked at online scam centers in eastern Myanmar began Thursday, after the rescued workers were taken across the border to Thailand and put on chartered flights to China.

China began repatriating 200 of its citizens who worked in cyber fraud operations in Myanmar, the first batch returning from the centers international groups have said are a nexus of human rights abuses and criminal activity.

China will fly home about 200 of its nationals found in scam-running compounds on the Thai-Myanmar border, a Thai security official said on Tuesday, as part of a multinational effort to crack down on illegal online operations run from the region.
