More than 24000 abducted women and children were rescued by the police from across China 2011, a government report said on Sunday.
Some of the women were being forced into international prostitution rings.
The report released by the ministry of public security did not give the total number of women and children still missing. But the figure of the rescued gives a clear indication about how big the problem is in the country.
The report said 8660 kidnapped children and 15468 women were freed in hundreds of operations carried out across China.
In one case, the police busted an international ring of traffickers who were sending Chinese women to Angola in Africa for prostitution; 19 Chinese women were rescued and 16 suspects detained in this particular case.
The report also mentioned the ministry's work in facilitating abducted children to get home, such as setting up a DNA database for missing children.
The ministry reaffirmed its tough stance on trafficking and vowed sterner crackdowns against such crimes.
"Public security organs across China will deepen the campaign against abductions to save more women and children and work hard to reduce the number of abduction and trafficking cases," the ministry said
According to Associated Press, the exact numbers of victims are difficult to obtain as China's vast size, rural poverty and population of 1.3 billion mean many such cases never get reported beyond local areas.
“The rescued children are usually put into orphanages while authorities try to reunite them with their families. In order to identify the rescued children, an "anti-abduction" DNA database has been set up to match missing children with their families,” the news agency said.
It added the abductions are often fuelled by traditional preference for male heirs. The one-child policy has also driven a thriving market in baby boys, who fetch a considerably higher price than girls. Girls and women also are abducted and used as laborers or as brides for unwed sons.
Given how big the problem is even frequent crackdowns have failed to curb the menace; in December, the police rescued 200 children after uncovering two child-trafficking gangs and arrested more than 600 people.
