Beijing - Chinese authorities say 37 Chinese nationals have been extradited from the southwestern African country Angola, where they are accused of crimes against fellow Chinese citizens such as kidnapping, robberies, extortions and forcing them into prostitution.

Such crimes are a major concern for China, which has emerged as Africa's main trading partner and a major source of investment for infrastructure. As a result, a large number of Chinese are working and living on the African continent, and their presence has sparked problems such as violent crimes among Chinese nationals, especially in politically volatile countries.

The Ministry of Public Security said Saturday that Beijing worked with Angolan police in the operation that destroyed 12 Chinese gangs, resolved 48 criminal cases and rescued 14 Chinese victims. - Sapa-AP
