A/HRC/11/7 page 9 the principle of non-refoulement, which in the case of children should be construed as including socio-economic conditions in countries of origin; and family reunification entitlements in countries of origin and destination. 35. The minimum measures that should be taken into consideration in the process of initial assessment once unaccompanied or separated children enter a country of transit or destination is also addressed in general comment No. 6; they include prioritized identification of a child as separated or unaccompanied immediately upon arrival at ports of entry or as soon as their presence in the country becomes known to the authorities including age assessment (art. 8); prompt age appropriate and gender sensitive registration and determination of the identity of the child, in a language the child understands, by professionally qualified persons; the recording of further information in order to meet the specific needs of the child, including the reasons for being separated or unaccompanied; and an assessment of particular vulnerabilities, such as health, physical, psychosocial, material and other protection needs, including those deriving from domestic violence, trafficking or trauma. 36. Children who are victims of transnational organized crime should be identified as such in accordance with existing international standards. Therefore, child victims should not be regarded as criminals or irregular migrants, but as victims entitled to appropriate assistance and measures of protection. Applicable legal instruments, such as the Optional Protocol to the Convention on the Rights of the Child on the sale of children, child prostitution and child pornography and the two protocols supplementing the United Nations Convention against Transnational Organized Crime contain similar provisions emphasizing that States parties should take appropriate measures to protect the rights and interests of child victims of those practices and adapt procedures that take into consideration their special needs and vulnerabilities. Furthermore, principle 1 of the Recommended Principles and Guidelines on Human Rights and Human Trafficking (E/2002/68/Add.1) suggests, that children who are victims of trafficking should be identified as such, while principle 8 recommends that special measures be taken for their protection and support. 37. Additional international legal instruments may complement the general legal framework in specific circumstances. For example, in cases of detention of unaccompanied migrant children, legal instruments dealing with consular relations18 and with human rights in the context of the administration of justice19 may play an important role for the protection of the child. Maritime law is relevant in cases of the interception and rescue of migrant children at sea,20 and 18 See for example the Vienna Convention on Consular Relations, art. 36, para. 1 (b). 19 See for example the United Nations Rules for the Protection of Juveniles Deprived of Their Liberty, the United Nations Standard Minimum Rules for the Administration of Juvenile Justice and the Guidelines for Action on Children in the Criminal Justice System. 20 See for example the United Nations Convention on the Law of the Sea, art. 98.
