An ongoing effort targeting scam compounds along Thailand's border with Myanmar has led to only a small proportion of workers there being pulled out, a top Thai opposition lawmaker said, calling for more comprehensive measures to stomp out a booming illegal industry.

Thousands of human trafficking victims await repatriation in Myanmar, straining resources in neighboring Thailand.

The crackdown coordinated among Thailand, Myanmar and China follows Thai Prime Minister Paetongtarn Shinawatra's visit to Beijing this month, where she told Chinese leader Xi Jinping that Thailand would act against the scam networks that have drawn in hundreds of thousands of people.
