GUIYANG?-?Chinese police have cracked down two children trafficking rings, and rescued 14 children from southwest China's Guizhou Province, local police said Saturday.

So far, 38 suspected members from the two rings have been captured in a joint hunting efforts by police of Guizhou, Henan, Chongqing, and Zhejiang, said Li Song, a police officer with the public security section of the railway bureau in Guiyang.

The rings were identified after police seized two suspects, surnamed Wang and Xiao, on train on December 8 last year, saving two baby infants. Wang and Xiao, with their family members involved, "purchased" children in Guizhou and transferred them by train to Henan Province for sale, said Li.

DNA tests would be carried out for the rescued children to find their families, he said.

In recent years, China has taken a tough stance on trafficking and repeatedly launched crackdowns. Official figures show that last year,police across the country rescued 8,660 abducted children and 15,458 women in busts of 3,195 human trafficking rings.
