Chinese authorities have detained a key suspect in human trafficking cases linked to online scam networks in Myanmar.

Thailand and China will work together to combat fast-growing networks of illegal call centres along the Thai border with Myanmar and Cambodia, often staffed by trafficked workers, that aim to defraud people in phone and online scams.

A key suspect wanted in connection with human trafficking and telecoms fraud cases - including that of Chinese actor Wang Xing - has been arrested and sent to China, Beijing's Ministry of Public Security said in a statement posted on its website on Sunday.
