Human trafficking crimes are posing a grave threat to Vietnamese security.
On Wednesday, the government's anti-human trafficking committee claimed that police across the country have identified nearly 4,000 suspects nationwide.
At an anti-domestic violence and human trafficking conference held in Hanoi the same day, the 130/CP Steering Committee reported that since 2004 local agencies have logged 1,949 cases of human trafficking involving 4,793 victims.
Most of the cases took place at border crossings between Vietnam and China (65 percent), while others occurred between the Vietnam-Cambodia and Vietnam-Laos borders, the committee was quoted as saying by VTC News.
The victims were mainly poorly educated women and children living in underprivileged areas, it said. They were promised well-paying jobs in cities or town. Instead, they were sold to other countries as sex workers and to criminal syndicates abroad.
Some, meanwhile, were sent to China where they had their internal organs removed, it added.
To Cong Luan, a 20-year-old student in the central province of Ninh Thuan, for example, was cheated out of his kidney in China in 2008; he died in September of the same year. His story attracted broad media attention at the time.
More and more infants and fetuses became the victims of human traffickers, according to the committee.
In 2008, police busted a ring in Hanoi that had sold 40 babies to China for between VND10 and 30 million (US$514.13-1,542), the anti-human trafficking committee cited.
It also noted that among the reported cases, some agencies discovered that men in northern provinces had been sold into slavery in Chinese mines.
