PHNOM PENH, Cambodia (AP) — Police in Cambodia have arrested more than 200 Chinese citizens accused of defrauding people in China over the internet.

Gen. Y Sok Khy, director of the Interior Ministry’s Department of Counter-Terrorism and Transnational Crime, said 36 women were among the 235 Chinese arrested Monday in three different villages in Takeo province, south of the capital, Phnom Penh.

Online scams by Chinese gangs that operate from foreign countries and target mainland Chinese are common throughout Southeast Asia and have been found as far away as Kenya and Spain. Cambodia has arrested and sent at least 1,000 Chinese and Taiwanese residents allegedly involved in such schemes to China since 2012.

The scams are carried out by making phone calls over the internet and employing deception, threats and blackmail against the victims.
