A/HRC/9/21 page 12 44. In a similar vein, the Special Rapporteur also proposes, during her mandate, to urge States that have not already done so to sign and ratify the Optional Protocol to the Convention on the Rights of the Child on the sale of children, child prostitution and child pornography. 45. With respect to the strategies deployed by States, while the previous Special Rapporteur identified and listed examples of best practice, he also noted a regrettable absence of standards and protocols for the care of child victims of trafficking and commercial sexual exploitation (A/HRC/7/8 paras. 27 to 69 and 75 to 77). The Special Rapporteur proposes to help develop standards and procedures for the care of child victims of sale, sexual exploitation or pornography, in consultation and close cooperation with all partners. 46. With regard to country visits, the Special Rapporteur will in the first instance undertake the visits already planned by her predecessor, to which the States concerned have agreed. The transnational and regional perspective will be a priority in country visits, along with joint or coordinated visits with other special procedures mandate holders, in particular the Special Rapporteur on contemporary forms of slavery and the Special Rapporteur on the human rights aspects of the victims of trafficking in persons, in particular women and children. 47. The States to be visited will be selected based on the following criteria: • Follow-up to recommendations made on previous visits • Analysis of communications from countries • Countries that have undergone or are due to undergo universal periodic review • Countries that are due to report or have reported to the Committee on the Rights of the Child, where the Committee has made recommendations relevant to the mandate • Proposals from NGOs or United Nations specialized agencies, funds or programmes 48. The Third World Congress Against Sexual Exploitation of Children and Adolescents will be held in Rio de Janeiro, Brazil from 25 to 28 November 2008, and the Special Rapporteur has made known her wish to attend and to chair a round table on “Areas for bilateral and/or multilateral cooperation to prevent and combat sex tourism and child pornography”. 49. Throughout her mandate, the Special Rapporteur will favour a participatory, consultative approach, through sustained partnership with Governments, civil society, international, regional and national NGOs, United Nations agencies, international intergovernmental organizations, other special procedures mandate holders, treaty bodies and the private sector. This partnership will be developed through exchanges of information, preparation of country visits, contribution to thematic reports, organization of workshops and seminars, identification of best practices, production of material (information and awareness-raising, standards and guidelines and so on) and, most of all, follow-up to the implementation of recommendations. To that end partnership mechanisms will be established, including an updated database (national, regional and international NGOs, United Nations agencies, international forums, intergovernmental organizations, the private sector and so on); questionnaires; and regular updating of the website.
