According to this article from Channel News Asia, China has recently updated its rules regarding the adoption of abandoned or trafficked children, allowing a child to be adopted if authorities do not find parents or guardians during a year-long search. Many trafficked or abandoned children currently end up in state-run orphanages while authorities search for their families. Now, according to this article, children will be able to be placed in adoptive homes while authorities search for their families, under the condition that adoptive families return the children to the biological parents if found.
