Cambodian government had promoted the policy “Family Reunion Program” between 2016 and 2018, and sent 30% of the children staying at each residential care institution each year. It was started with a survey on residential care institutions. Cambodian government found so many unregistered residential care institutions. And also number of children staying at the residential care institutions are found to be “one out of three hundred and fifty children.” And moreover, many of those children have families and are not orphans. We visited Cambodia in March, 2019 to interview the children who went back to their family to investigate if they are well taken care of and they are going to school.
