A/HRC/4/104 page 7 12. The Committee has consistently welcomed the establishment of national human rights institutions that monitor the rights of women, and recognized the ratification of the Convention on the Elimination of All Forms of Discrimination against Women and its Optional Protocol as positive measures to protect and promote women’s rights. C. International Convention on the Elimination of All Forms of Racial Discrimination 13. The Committee on the Elimination of Racial Discrimination has referred to double discrimination affecting women and gender-related racial discrimination issues in more than half of the concluding observations it adopted on States parties’ reports during its sixty-eighth and sixty-ninth sessions (2006). The Committee expressed concern over the lack of assessment of discrimination against women belonging to ethnic minorities.24 It regretted the lack of statistical information, disaggregated also by gender, on the economic situation of indigenous peoples and their communities and their enjoyment of the rights protected under article 5 of the Convention.25 In particular, the Committee noted the lack of adequate statistical data on indigenous women’s participation in public life. When information was provided, it noted the low number of minority and indigenous women occupying positions of responsibility within the State party’s administrative, political or private sector.26 The Committee also noted high illiteracy rates among women and low primary school attendance of girls among the indigenous population of some States parties.27 Furthermore, it raised the issue of the nationality law of a State party which did not grant citizenship to children of women nationals married to non-nationals, as it does in the case of a father married to a foreigner. The Committee warned that this may lead to a situation of statelessness and urged the State party to review its legislation on the acquisition of nationality in order to ensure that both parents can transmit their citizenship to their children.28 The Committee also addressed various forms of violence against women including trafficking of women and girls belonging to particular national or ethnic groups or non-citizens for the purpose of sexual exploitation;29 the particular vulnerability of foreign and indigenous women to domestic violence and the lack of appropriate strategies to eradicate such violence; cases of forced sterilization of indigenous women without their knowledge or full and 24 See Official Records of the General Assembly, Sixty-first Session, Supplement No. 18 (A/61/18), para. 173. 25 Ibid., para. 136. 26 Ibid., paras. 116, 141 and 224. 27 Ibid., para. 120. 28 Ibid., para. 366. 29 Ibid., paras. 393 and 181.
