Although a rising number of Cambodian women are being sold as brides in China, complaints and convictions are on the decline, with many victims refusing to speak out because their families are colluding with trafficking rings, a regional police chief says.

Thousands of Cambodian women have gone to China in recent years on the pretense that they would be able to marry, work and send money home to their families, only to find themselves sold into forced — and often abusive — marriages, campaigners say.

But survivors who return to Cambodia often decide against filing police complaints because they fear implicating their relatives in criminality, according to Thol Meng, deputy chief of the anti-trafficking bureau in the province of Kompong Cham.
