HANOI, Vietnam (AP) _ Two Vietnamese officials were arrested in the southern province of An Giang for their alleged roles in selling 92 children to foreigners for adoption, provincial officials said Saturday.

Their arrests brought to six the number of people arrested for alleged involvement in a child-trading ring.

Vietnam has allowed foreigners to adopt Vietnamese children since the country launched economic liberalization in the mid-1980s. There are no numbers available on how many children have been sent abroad.

In this case, Pham Thanh Hai, director of the Long Xuyen center for orphans and the elderly, and Pham Thi Tinh, deputy chief of the nationality division of the provincial justice department, were arrested Thursday, said Nguyen Van Ngoc, deputy chairman of the provincial Red Cross.

Ngoc said the six suspects sold 92 children to foreigners over the past two years. The children were sent to France and Switzerland and several other countries, he said.

Under Vietnamese regulations, children for foreign adoption must come from the center for orphans.

Ngoc said the suspects allegedly solicited children from poor families, prepared false documents and charged the prospective parents $2,000.
