Chinese state media say authorities have rescued 89 children and arrested 369 suspects in a crackdown on suspected human trafficking gangs.

Newspapers says the arrests were made in two operations this month. In one case in the southern regions of Guangdong and Guangxi provinces, police detained 39 people suspected of being involved in abducting and selling children from Vietnam. Eight infants were rescued in the operation.

Police say most of the suspects are Vietnamese residents.

In the other operation, 81 infants were rescued and 330 people were arrested in a crackdown that spanned 14 provinces and autonomous regions.

China has a thriving black market in children and women. The China Daily newspaper says national police have uncovered more than 39,000 cases of human trafficking since 2009, involving more than 14,000 women and more than 8,700 children.
