CRC/C/15/Add.93 page 6 poverty alleviation programmes with special emphasis on the access to health care and education of children, in particular the most vulnerable groups of children. 26. Although the Committee is aware of the State party's achievements in the field of education, it remains concerned at the high drop-out rate between primary and secondary school and the high repetition rate at both levels, at the gender disparities in secondary school enrolment and at disparities in access to education between rural and urban areas. It recommends that the State party strengthen its educational policies and system in order to reduce gender and geographical disparities and to establish retention programmes and vocational training for drop-out students. 27. Though the Committee is aware that the reform of the primary education curricula has included measures to fulfil the rights of the child to leisure and recreational and cultural activities, it remains concerned about the insufficiency of these measures, in particular for children living in urban-poor and rural areas. In the light of article 31 of the Convention, the Committee recommends that the State party strengthen its measures to improve children's access to leisure and to recreational and cultural activities, especially for the most vulnerable groups of children. 28. While the Committee acknowledges the State party's policies for the protection of refugees, it remains concerned at the lack of specific provisions in its domestic legislation concerning the rights of asylum seeking and refugee children and the right to family reunification. In the light of article 22 of the Convention, the Committee recommends that the State party undertake appropriate measures to adopt legislation to protect all the rights of asylum seeking and refugee children. Technical assistance from the Office of the United Nations High Commissioner for Refugees (UNHCR) could be requested in this regard. 29. The Committee is concerned at the insufficient measures addressing the issues of child labour and economic exploitation, including domestic labour and sexual exploitation of children. In this regard, the lack of data and research is also a matter of concern to the Committee. The Committee is further concerned at the increasing number of children living and/or working on the streets, who require special attention because of the risks they are exposed to. The Committee recommends that the State party give specific attention to undertaking research on and monitoring the situation of children living and/or working on the streets and those involved in hazardous labour, including domestic service and prostitution. The Committee also recommends that the State party develop national policies on the prevention and the elimination of the most hazardous forms of child labour. The Committee suggests that the State party consider seeking technical assistance from ILO in this area. In addition, the Committee encourages the State party to consider ratifying ILO Convention No. 138 concerning minimum age for admission to employment. 30. While the Committee takes note of the State party's efforts to combat the trafficking and sale of children, it remains concerned about the lack of preventive measures in this area. Concerning the trafficking of boys and girls into neighbouring countries for work, including prostitution, the Committee recommends that measures be taken on an urgent basis, such as a comprehensive programme of prevention, including an awareness-raising campaign
