CRC/C/15/Add.56 page 7 non-registration of new-born girls is a major factor contributing to the imbalance in the ratio of boys to girls. The Committee, while noting that the State party has adopted measures to reduce the under-reporting of girl children, recommends that urgent measures be taken to develop more widespread awareness of the importance of registration. In the light of recent developments such as population movements within the country, the Committee also recommends that the State party consider the possibility of reviewing the effectiveness of the existing system of registration. 38. It is the opinion of the Committee that further measures should be taken by the State party to promote the possibilities for children, particularly those who have been abandoned, to grow up in a home-like environment through, inter alia, fostering and adoption. The Committee also suggests that the State party review the present legislation on adoption, in the light of the principles and provisions of the Convention, notably those of its articles 20 and 21, so as to evaluate the effectiveness of national legislation in facilitating domestic adoption. 39. The State party is urged to take further action to improve the situation of children in welfare institutions. In this regard, the Committee wishes to draw the particular attention of the State party to the principles and provisions of the Convention, notably those of its articles 3 (3) and 25. The Committee recommends that a further review of the training provided to the staff of such institutions be undertaken. The training should be reviewed from the perspective of securing the most effective pedagogical, professional and child-oriented approach to the provision of care. Measures are also required to ensure the effective supervision of staff and the periodic review of the treatment provided to children in such institutions. In the light of other issues raised during the dialogue with the State party, the Committee also suggests that further consideration be given to reviewing the systems in place for monitoring welfare institutions and for providing such institutions with adequate financing. Within the framework of facilitating access to knowledge and the sharing of expertise and experiences on these matters, including in the light of the provisions of articles 4, 23, 24, 28 and 45 of the Convention, the Committee suggests that consideration be given to the possibility of inviting the United Nations Children’s Fund, the World Health Organization and the United Nations Educational, Scientific and Cultural Organization to cooperate with the State party in this regard. 40. The Committee suggests that a review be undertaken of measures to ensure that children in the Tibet Autonomous Region and other minority areas are guaranteed full opportunities to develop knowledge about their own language and culture as well as to learn the Chinese language. Steps should be taken to protect these children from discrimination and to ensure their access to higher education on an equal footing. 41. The Committee recommends that the State party seek a constructive response to the concerns expressed in paragraph 20 above. 42. The Committee concurs with the contents of the observations adopted by the Committee against Torture where the points raised are relevant to the situation of children below the age of 18. The Committee recommends that a thorough review of the legislative and administrative measures and procedures
