Online scams by Chinese gangs that operate from foreign countries and target mainland Chinese are common throughout Southeast Asia. Since 2012, Cambodia has sent at least 1,000 Chinese and Taiwanese residents involved in such schemes to China.
The arrests have caused controversy because suspects from Taiwan are usually deported directly to China in deference to Beijing, which views Taiwan as its own territory without sovereign legal status.
Taiwan rejects China's claim to its territory and wants its citizens returned there.
The deportations highlight Beijing's efforts to assert its sovereignty over Taiwan, and the leverage it wields over smaller nations to achieve that.
