Thousands of Cambodian children were adopted overseas between the late 1980s and 2009. During that time it emerged that many of the adopted children were not orphans but had parents who placed them in orphanages because of extreme poverty. Their parents placed them there on the understanding that they would return home at a later date. They did not consent to their children's adoption. Instead, orphanage directors, with the help of local authorities, created documents falsely stating that the children were orphans or had been abandoned.
