CRC/C/15/Add.142 page 10 48. The Committee recommends that the State party implement the National Programme for the Prevention of Sexual Violence for 2000-2004, in particular its rehabilitation and reintegration aspects. Further, it recommends that the State party undertake a study of commercial sexual exploitation and abuse of children in order to understand its scope and causes and to develop programmes for monitoring the problem and to prevent and combat it, taking into account the Agenda for Action adopted at the World Congress against Commercial Sexual Exploitation of Children. In particular, it encourages the State party to prevent the criminalization and stigmatization of the victims. Children living in the streets 49. The Committee expresses its concern at the significant number of children living in the streets. It notes that even though the Law on the Protection of the Rights of the Child covers children living in the street, no specific mechanisms have been established for its implementation and that assistance to the children living in the streets is generally provided only by non-governmental organizations. 50. The Committee recommends that the State party support existing mechanisms to provide children living in the streets with food, clothing, housing, health care and educational opportunities, including vocational and life-skills training. Moreover, the State party should ensure that these children are provided, whenever necessary, with rehabilitation services for physical, sexual and substance abuse; protection from police brutality; and services for reconciliation with their families. Children belonging to minority groups 51. The Committee notes with concern that the Education Law of 1998 foresees that, as of 2004, all State-funded schools will provide secondary education in Latvian only, while bilingual education will be available only until 9th grade. Further, it notes the slow pace of the National Programme for Integration of Society in Latvia, owing in particular to a lack of funding. 52. The Committee encourages the State party to ensure that children belonging to minorities can also use their own language in secondary education, in accordance with articles 29 and 30 of the Convention. Further, it encourages the enforcement of the integration process, in particular at community level, and the provision of more information about the process. Optional protocols 53. The Committee takes note of the fact that the Government of Latvia has started the internal procedure of accession to the Optional Protocols on the sale of children, child prostitution and child pornography and on the involvement of children in armed conflicts. 54. The Committee invites the State party to continue this process and to ratify the two Optional Protocols to the Convention.
