Children belonging to indigenous and minority communities 78. The Committee expresses its concern about the situation of children belonging to indigenous, tribal and minority communities who are subject to both stigmatization and discrimination. In particular, it is concerned about widespread poverty among indigenous peoples and minorities and the limited enjoyment of their human rights, in particular, concerning their access to social and health services and education. The Committee is also concerned that many indigenous and minority children are stateless and/or have no birth registration and are at increased risk for abuse and exploitation. It further notes that there is at present insufficient demographic data on the hill-tribe population in Thailand. 79. The Committee recalls the State party’s obligations under articles 2 and 30 of the Convention and recommends that it ensure the full enjoyment, by indigenous and minority children, of all of their human rights equally and without discrimination. In this regard, the Committee urges the State party to take adequate measures to protect the rights of indigenous and minority children to preserve their historical and cultural identity, customs, traditions and languages, taking into account the recommendations adopted by the Committee on its day of general discussion on the rights of indigenous children in September 2003. It also urges the State party to continue to develop and implement policies and programmes in order to ensure equal access to culturally appropriate services, including social and health services and education. The Committee also recommends that the State party ensure access to birth registration for all indigenous and minority children and continue to implement measures to address the issue of statelessness.
