E/C.12/CHN/CO/2 (c) Take all necessary measures to make secondary education, including technical and vocational education, generally available and accessible to all; (d) Take all necessary measures to reduce dropout rates for children belonging to ethnic minority groups and children of rural-to-urban migrant workers; Cultural rights of ethnic minorities 36. The Committee is concerned that ethnic minorities continue to face severe restrictions in the realization of their right to take part in cultural life, including the right to use and teach minority languages, history and culture, as well as to practise their religion freely. Despite the measures adopted by the State party, the Committee is concerned about the restrictions faced by Tibetans and Uighurs, in particular regarding the restriction of education in the Tibetan and Uighur languages (art. 15). The Committee recommends that the State party take all necessary measures to ensure the full and unrestricted enjoyment by minorities, including Tibetans, Uighurs and Inner Mongolians, of their right to enjoy fully their own cultural identity and take part in cultural life, and to ensure the use and practice of their language and culture. The Committee also recommends that the State party take adequate measures to protect cultural diversity and promote awareness of the cultural heritage of ethnic, religious and linguistic minorities. Cultural rights and freedom of expression and information 37. The Committee is concerned about the lack of information on measures taken by the State party to prevent limitations on freedom of information and expression in the State party which may hinder the realization of the right to take part in cultural life and to benefit from technological and scientific progress (art. 15). The Committee reiterates its previous recommendation (E/C.12/1/Add.107, para. 68) and urges the State party to take effective measures to remove restrictions on freedom of expression and information in the State party, and to enable all persons under its jurisdiction to take part in cultural life, enjoy the benefits of scientific progress and its applications, and benefit from the protection of the moral and material interests resulting from any scientific, literacy or artistic production of which they are the authors. Respect for rights of labour and human rights activists and their lawyers 38. The Committee is concerned at reports of instances where labour and human rights activists, and their lawyers, have been victims of repression and reprisals when taking up cases of violations of economic, social and cultural rights (arts. 2, 10, 12 and 13). The Committee urges the State party to protect human rights and labour activists, as well as their lawyers, against any form of intimidation, threat or retaliation for taking up cases of violations of economic, social and cultural rights, and to ensure full respect for their own economic, social and cultural rights. The Committee also urges the State party to guarantee that human rights and labour activists, as well as their lawyers, have adequate access to health care in all circumstances, and that their children fully enjoy the right to education. The Committee also calls on the State party to ensure that all allegations of reprisals and abuse are promptly and thoroughly investigated, and that perpetrators are brought to justice. 12
