A/HRC/10/31 page 11 rights. The report advocates for a human rights-based approach to migration and recalls that respecting human rights is not only a legal obligation but also a precondition for our societies to grow and prosper in peace and security. 41. Together with the Government of Mexico, OHCHR co-organized in September 2008, the International Meeting on the Protection of the Rights of Children in the Context of International Migration. At the Meeting, participants discussed aspects related to the human rights of children in the context of migration, and adopted a set of recommendations to that effect. As the convenor of the steering committee for the promotion of ratification of the Migrant Workers Convention, in which the International Labour Office (ILO), the International Organization for Migration, the United Nations Children’s Fund and several non-governmental organizations participate, OHCHR continued its advocacy for the ratification of the Convention. States and intergovernmental organizations need to review existing migration 42. frameworks, which, by failing to respect the basic human rights of migrants, may increase their vulnerability and thus their risk of becoming victims of trafficking. Particular attention should be given in this regard to the preservation of the principle of family unity. States have an obligation to prevent trafficking and associated human rights violations, including through addressing the factors that increase vulnerability to trafficking, such as inequality, poverty and discrimination. 43. OHCHR developed the Recommended Principles and Guidelines on Human Rights and Human Trafficking (E/2002/68/Add.1) in 2002 as a framework and reference point for our own work on this issue; we encourage States and intergovernmental organizations to implement the Principles and Guidelines in their own efforts to prevent trafficking and to protect the rights of trafficked persons. F. Freedom of expression and incitement to racial and religious hatred 44. In accordance with Council resolution 7/19 on combating defamation of religions, the Office submitted, in September 2008, a report on the implementation of that resolution (A/HRC/9/7) as well as a study compiling relevant existing legislations and jurisprudence concerning defamation of and contempt for religions (A/HRC/9/25). In addition, the report of the Secretary-General of October 2008 (A/63/365) focuses on measures and activities undertaken by Member States, United Nations human rights mechanisms and treaty bodies, United Nations bodies, regional organizations, national human rights institutions and non-governmental organizations with regard to the implementation of General Assembly resolution 62/154. 45. In order to contribute further to the ongoing debate on the demarcation line between freedom of expression and hate speech, especially in relation to religious issues, OHCHR convened an expert meeting to address the issued of freedom of expression in the context of advocacy of religious hatred that constitutes incitement to discrimination, hostility or violence. A substantive report on the seminar, which was held in Geneva on 2 and 3 October 2008, is submitted as an addendum to the present report (A/HRC/10/31/Add.3).
