A court in the southern province of An Giang on Monday sentenced two women to nine and 11 years in jail for trafficking 21 Vietnamese women to China.
Nguyen Thi Huong, 50, received nine years and Nguyen Thi Hong Phuong, 40, the longer term.
Phuong, Huong and the latter’s sister Nguyen Thi Thom, who is still at large, had brought 21 women from poor families in the Mekong Delta to China between November 2012 and December 2013, the indictment said.
Phuong herself had been trafficked to China by Huong, but she later came back to Vietnam to help Huong look for more women.
Police launched an investigation after several victims managed to escape in February last year.
Phuong was arrested soon after that when she was trying to escape to Cambodia. Huong turned herself in.
Investigation found Phuong earned VND82.5 million (US$3,670) and Huong VND168.1 million ($7,472) from trafficking the women.
Phuong said at the court that her Chinese husband forced her into the crime. She said the man threatened to sell their own son if she could not find Vietnamese women aged between 18 and 29.
Of all the victims, 18 have returned home. Three are still unaccounted for.
Most of them were sold to Chinese men who could not find a wife.
