CRC/GC/2002/2 page 7 22. NHRIs should also cooperate with the special procedures of the Commission on Human Rights, including country and thematic mechanisms, in particular the Special Rapporteur on the sale of children, child prostitution and child pornography and the Special Representative of the Secretary-General for Children and Armed Conflict. 23. The United Nations has a long-standing programme of assistance for the establishment and strengthening of national human rights institutions. This programme, which is based in the Office of the High Commissioner for Human Rights (OHCHR), provides technical assistance and facilitates regional and global cooperation and exchanges among national human rights institutions. States parties should avail themselves of this assistance where necessary. The United Nations Children’s Fund (UNICEF) also offers expertise and technical cooperation in this area. 24. As articulated in article 45 of the Convention, the Committee may also transmit, as it considers appropriate, to any specialized United Nations agency, OHCHR and any other competent body any reports from States parties that contain a request or indicate a need for technical advice or assistance in the establishment of NHRIs. NHRIs and States parties 25. The State ratifies the Convention on the Rights of the Child and takes on obligations to implement it fully. The role of NHRIs is to monitor independently the State’s compliance and progress towards implementation and to do all it can to ensure full respect for children’s rights. While this may require the institution to develop projects to enhance the promotion and protection of children’s rights, it should not lead to the Government delegating its monitoring obligations to the national institution. It is essential that institutions remain entirely free to set their own agenda and determine their own activities. NHRIs and NGOs 26. Non-governmental organizations play a vital role in promoting human rights and children’s rights. The role of NHRIs, with their legislative base and specific powers, is complementary. It is essential that institutions work closely with NGOs and that Governments respect the independence of both NHRIs and NGOs. Regional and international cooperation 27. Regional and international processes and mechanisms can strengthen and consolidate NHRIs through shared experience and skills, as NHRIs share common problems in the promotion and protection of human rights in their respective countries. 28. In this respect, NHRIs should consult and cooperate with relevant national, regional and international bodies and institutions on children’s rights issues.
