The Committee is concerned that the access to sports facilities to a large degree still remains dependant on family’s income. 64. In the light of article 31 of the Convention, the Committee encourages the State party to continue and strengthen its focus on children’s sports, play and cultural activities, including through adequate resource allocation and technical cooperation projects. 7.

The Committee welcomes the progress made in establishing a clear legal framework governing the treatment of refugees by way of adopting the Law on Asylum in December 2007. The Committee is concerned that a large percentage of the returned children remain unregistered and therefore do not have access to all basic services. 66. The Committee recommends that the State party take all necessary measures to ensure that all children, including child returnees, are fully registered and effectively benefit from the social protection systems.

Furthermore, the Committee regrets the lack of data in this respect. 68.
