CMW/C/GC/3-CRC/C/GC/22 best interests of the child (art. 3); the right to life, survival and development (art. 6); and the right of the child to express his or her views in all matters affecting him or her, and to have those views taken into account (art. 12). States should adopt measures, including legislative and other policy tools, aimed at ensuring that those principles are upheld in practice and brought into the mainstream of all policies affecting children in the context of international migration, and in the interpretation and analysis of the specific obligations as clarified in joint general comment No. 4 (2017) of the Committee on the Protection of the Rights of All Migrant Workers and Members of Their Families and No. 23 (2017) of the Committee on the Rights of the Child on State obligations regarding the human rights of children in the context of international migration in countries of origin, transit, destination and return. 20. The Committees reaffirm the application of articles 41 of the Convention on the Rights of the Child and 81 of the International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families, and reiterate that the provisions in domestic and international legislation that are the most conducive to the realization of the rights of all children in the context of international migration shall apply in cases where standards differ. Furthermore, a dynamic interpretation of the Conventions based on a child-centred approach is necessary to ensure their effective implementation and the respect, protection and fulfilment of the rights of all children in the context of the increasing number of challenges that migration poses for children. A. Non-discrimination (articles 1 and 7 of the International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families; article 2 of the Convention on the Rights of the Child) 21. The principle of non-discrimination is fundamental and, in all its facets, applies with respect to children in the context of international migration. 5 All children involved in or affected by international migration are entitled to the enjoyment of their rights, regardless of the children’s or their parents’, legal guardians’ or family members’ age, gender, gender identity or sexual orientation, ethnic or national origin, disability, religion, economic status, migration/documentation status, statelessness, race, colour, marital or family status, health status or other social conditions, activities, expressed opinions, or beliefs. This principle is fully applicable to every child and his or her parents, regardless of the reason for moving, whether the child is accompanied or unaccompanied, on the move or otherwise settled, documented or undocumented or with any other status. 22. The principle of non-discrimination shall be at the centre of all migration policies and procedures, including border control measures, and regardless of the migration status of children or their parents. Any differential treatment of migrants shall be lawful and proportionate, in pursuit of a legitimate aim and in line with the child’s best interests and international human rights norms and standards. Similarly, States parties should ensure that migrant children and their families are integrated into receiving societies through the effective realization of their human rights and access to services in an equal manner with nationals. 23. The Committees recommend that States parties adopt adequate measures to combat discrimination on any grounds and to protect children from multiple and intersecting forms of discrimination, throughout the migration process, including in and after returning to the country of origin, and/or as a result of their migration status. In order to achieve such a goal, States parties should strengthen efforts to combat xenophobia, racism and discrimination and take all appropriate measures to combat such attitudes and practices, and to collect and disseminate accurate, reliable and updated data and information in that regard. States should also promote the social inclusion and full integration of families affected by international migration into the host society and implement programmes for improving knowledge about migration and addressing any negative perceptions regarding migrants, with the aim of protecting children affected by international migration and their families from violence, discrimination, harassment and bullying, and fulfilling their access to rights 5 See Committee on the Rights of the Child, general comment No. 6, para. 18. 5
