CRC/C/THA/CO/3-4 52. The Committee reiterates its previous recommendations that the State party: (a) Undertake a comprehensive study to assess the situation of children placed in institutions, including their living conditions, care plans and services provided; (b) Set clear standards for existing institutions and the foster care system, including rules for the involvement of children and their parents in decision-making processes in accordance with article 9 of the Convention and ensure periodic review of the placement of children, in light of article 25 of the Convention. In this regard, the Committee encourages the State party to complete and operationalize the National Strategy on Temporary Family-based Care ensuring the best interests of the child; (c) Ensure that all alternative care institutions and programmes are well monitored, including by independent complaint monitoring mechanisms and nongovernmental organizations, with a view to ensuring the protection of children’s rights, and provide children with easy access to these mechanisms; (d) Pursue all necessary measures to allow children placed in institutions to return to their families whenever possible and use the placement of children in institutions as a measure of last resort; (e) Take proactive measures for family strengthening and preservation to prevent widespread institutionalization of children. The Committee recommends that State party take into account the Guidelines for the Alternative Care of Children (General Assembly resolution 64/142 of 18 December 2009, annex). Adoption 53. The Committee welcomes the Child Adoption Act of 2010 and notes as positive that the State party gives priority to domestic adoption over inter-country adoption and has established regulations with regard to inter-country adoptions. In view of the large numbers of children in vulnerable situations in the State party, especially children with disabilities, children living in poverty, children in street situations and stateless children as well as the high incidence of human trafficking, the Committee recommends that the State party ensure an effective monitoring system of the adoption process. Abuse and neglect 54. The Committee welcomes the large scale study on the situation of violence against children initiated by the State party in 2011. However, it remains concerned that considerable numbers of children are neglected due to their parents’ migration to urban areas or AIDs-related death of parents. 55. The Committee recommends that the State party take necessary measures to create conditions for reunification of families separated due to migration, including possibilities for parents to bring their children with them to the urban areas. It also recommends that State party pays particular attention to orphan children and ensure that they are provided with foster families in a timely manner. 11
