The move follows an International Organisation for Migration (IOM) report highlighting the plight of an increasing number of Cambodian brides migrating to South Korea in marriages hastily arranged by brokers who make large profits.

Some 1,759 marriage visas were issued by South Korea in 2007, up from just 72 in 2004, the report said. While no systematic exploitation was uncovered, several cases of abuse did raise a red flag with the government, said You Ay, secretary of state with the Women's Affairs Ministry.

"Seven women have returned from South Korea because they could not stand what happened to them there," You Ay told AFP. "The government has temporarily suspended all (paperwork) for Cambodia women to marry foreigners," she said.

You Ay commented that the ban, which was approved last week, would be lifted after the government developed a legal framework to address mixed marriages. "This suspension is to prevent human trafficking through marriage," she said, adding that while the brides often receive as little as USD 1,000, agencies can make tens of thousands of dollars on each marriage.
