CRC/C/15/Add.237 page 20 80. The Committee urges the State party to gather additional information on all ethnic minorities and other marginalized groups and to elaborate policies and programmes to fully ensure the implementation of their rights without discrimination, taking into account the Committee’s recommendations on the rights of indigenous children made at its day of general discussion (CRC/C/133, para. 624). 9. Optional Protocols 81. The Committee encourages the State party to ratify and implement the Optional Protocols to the Convention on the Rights of the Child on the sale of children, child prostitution and child pornography, and on the involvement of children in armed conflict. 10. Dissemination of documentation 82. In light of article 44, paragraph 6, of the Convention, the Committee recommends that the second periodic report and written replies submitted by the State party be made widely available to the public at large and that the publication of the report be considered, along with the relevant summary records and the concluding observations adopted by the Committee. Such a document should be widely distributed in order to generate debate and awareness of the Convention, its implementation and monitoring within the Government, the Parliament and the general public, including concerned non-governmental organizations. The Committee recommends that the State party request international cooperation in this regard. 11. Periodicity of submission of reports 83. Finally, in light of the recommendation on reporting periodicity adopted by the Committee and described in the reports on its twenty-ninth (CRC/C/114) and thirty-second (CRC/C/124) sessions, the Committee underlines the importance of a reporting practice that is in full compliance with the provisions of article 44 of the Convention. An important aspect of States parties’ responsibilities to children under the Convention is ensuring that the Committee on the Rights of the Child has regular opportunities to examine the progress made in the Convention’s implementation. The Committee recommends that the State party submit its next periodic report on 13 August 2008, the due date of the fourth periodic report. This report will combine the third and fourth periodic reports. Such a report should not exceed 120 pages (see CRC/C/118). The Committee expects the State party to report every five years thereafter, as foreseen by the Convention. -----
