E/CN.4/2006/73 page 15 situation of family members left behind; the promotion of the positive aspects of migration by receiving countries or lack thereof; the promotion of a holistic approach to problems raised by migration that would take into account issues linked to economic and social development. 71. Economic and social issues have a particular impact on children involved in the migration process. Children of migrants who are left behind in countries of origin, leading to the occurrence of what is sometimes known as “broken” families, may suffer many serious problems. Existing limitations on family reunification can lead parents to take desperate measures, such as resorting to smugglers, in order to be reunited with their children. Such action can place children at a high risk of becoming victims of trafficking and other forms of abuse. Socio-economic problems such as poverty and destitution as well as current difficulties encountered by adults seeking to migrate are often at the origin of the phenomenon of unaccompanied child migrants, a particularly vulnerable group that requires special attention. Finally, it is important to recall that children of migrants often face many different types of discrimination and can have great difficulties in integrating in a new society. Children of migrants in an irregular situation are more exposed to marginalization and lack of support. 72. In his analysis of human rights violations suffered by migrants, including women and children, the Special Rapporteur intends to continue to address the developmental, economic and social factors at the core of many existing problems. Next year’s discussion at the high-level segment of the General Assembly will be a unique opportunity to further examine these issues. III. CONCLUSIONS 73. The themes outlined above are only a few of the many different and complex issues of concern that can come under the mandate. In consequence, the Special Rapporteur intends to continue to hold consultations regarding issues that require his attention. As indicated above, he hopes to give high priority to violations by both State and non-State actors as well as to practices that can lead to the particular vulnerability of migrants, such as the practice of subcontracting migrant labour. 74. As mentioned in his report to the General Assembly, the Special Rapporteur intends to focus initially on the question of demand through an analysis of real demand for migrant workers in Member States, by sector of the economy, over the past five years. 75. The Special Rapporteur will be guided in his work by the provisions of the relevant resolutions of the Commission on Human Rights and the General Assembly. With this in view, he hopes to continue to actively participate in the ongoing analysis within the United Nations system on migration and development and to be able to make a contribution in next year’s highlevel segment of the General Assembly. 76. In his work he intends to cooperate closely and coordinate with all relevant actors. 77. He also hopes to continue to participate in global, regional and subregional consultation processes on migration.
