BEIJING — Chinese police arrested 802 people on suspicion of child trafficking and rescued 181 children in a major operation spanning 15 provinces, the Chinese Ministry of Public Security said Friday. The recent operation broke up two trafficking rings and led to the arrests of the ring leaders, the ministry said in a statement posted on its website. Trafficking in children is a big problem in China. Its strict one-child policy has driven a thriving market in babies, especially boys because of a traditional preference for male heirs. State media report that a baby girl can fetch 30,000 to 50,000 yuan ($4,800 to $8,000) and that a baby boy sells for 70,000 to 80,000 yuan ($11,200 to $12,800). Last year, China rescued more than 8,000 children who were abducted or willingly sold by parents. — AP
