Coping with life after a daughter's disappearance

In the remote north of Vietnam, girls are disappearing. These girls, some as young as 13, are victims of bride trafficking, having been kidnapped and taken to China to be sold into marriage.
According to child rights organisation Plan International, this type of forced marriage has been growing slowly but steadily over the past decade.
Exacerbated by a decades-long one-child policy, a preference for sons is deeply embedded within Chinese society, leading to a growing gender imbalance within the country.
Photographer Vincent Tremeau travelled to Vietnam with Kirsty Cameron of Plan International to meet the families in one remote village where children have been taken.Fifty-six-year-old Do has been diagnosed with a terminal illness. Her only wish is to see her daughter Mi again before she dies. However, Mi has been missing for two years.
She was running errands in the market the day she was kidnapped, but all Do and her family have been able to establish was that she had been followed by two men when she left the stalls.
They traced Mi as far as Ha Giang, a city in the north of Vietnam, but by the time they got there, she was gone. Nobody had seen her, and they were told by local people that she had probably been taken to China to be sold as someone's wife.
Mi's framed photograph hangs on the wall of the family's house.
