A/HRC/25/48 stakeholders, particularly in the framework of country visits, in order to ensure enhanced ownership of the recommendations and the actions to be undertaken. 121. Close cooperation with States and other stakeholders, in particular during and after country visits, is critical to making a difference in children’s lives. Constructive dialogue involving all stakeholders has enabled the Special Rapporteur to bring about concrete change through the implementation of recommendations before and after the submission of her reports. Results have included States’ ratification of the Optional Protocol to the Convention on the Rights of the Child on the sale of children, child prostitution and child pornography, reform of legislation, increased compliance with international standards and strengthening of institutions and services. 122. Owing to the multidimensional nature of the sale and sexual exploitation of children and its intersection with a number of connected phenomena, including migration, the expansion of the Internet and related concepts such as various forms of child abuse and exploitation, close cooperation with the other existing human rights mechanisms is crucial, as well as with the private sector, particularly Internet service providers and the telecommunications, tourism and travel industries. 123. In order to ensure proper monitoring and follow-up to these recommendations, including the possibility of providing the necessary technical assistance — if requested — particularly in the framework of country visits, support to the mandate should be strengthened. 24
