E/C.12/MDA/CO/3 Cultural rights 74. The Committee is concerned that since the 2012 amendments to the law on identity documents, the national passport system has failed to fully recognize the names of persons belonging to ethno-linguistic minority groups, particularly Russian minorities (art. 15). 75. The Committee recommends that the State party take all measures necessary to ensure that persons belonging to ethno-linguistic minority groups, particularly Russian minorities, have their names, including patronymics, on their identity cards. D. Other recommendations 76. The Committee encourages the State party to consider ratifying the Optional Protocol to the International Covenant on Economic, Social and Cultural Rights. 77. The Committee recommends that the State party consider ratifying the International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families and the International Convention for the Protection of All Persons from Enforced Disappearance. 78. The Committee recommends that the State party take fully into account its obligations under the Covenant and ensure the full enjoyment of the rights enshrined therein in the implementation of the 2030 Agenda for Sustainable Development at the national level, with international assistance and cooperation when needed. Achievement of the Sustainable Development Goals would be significantly facilitated by the State party establishing independent mechanisms to monitor progress and treating beneficiaries of public programmes as rights holders who can claim entitlements. Implementing the Goals on the basis of the principles of participation, accountability and non-discrimination would ensure that no one is left behind. 79. The Committee recommends that the State party take steps to progressively develop and apply appropriate indicators on the implementation of economic, social and cultural rights, in order to facilitate the assessment of progress achieved by the State party in complying with its obligations under the Covenant for various segments of the population. In that context, the Committee refers the State party to, inter alia, the conceptual and methodological framework on human rights indicators developed by the Office of the United Nations High Commissioner for Human Rights (see HRI/MC/2008/3). 80. The Committee requests that the State party disseminate the present concluding observations widely at all levels of society, including at the national, provincial and municipal levels, in particular among parliamentarians, public officials and judicial authorities, and that it inform the Committee in its next periodic report about the steps taken to implement them. The Committee encourages the State party to engage with the two national human rights institutions, non-governmental organizations and other members of civil society in the follow-up to the present concluding observations and in the process of consultation at the national level prior to the submission of its next periodic report. 81. In accordance with the procedure on follow-up to concluding observations adopted by the Committee, the State party is requested to provide, within 18 months of the adoption of the present concluding observations, information on the implementation of the recommendations contained in paragraphs 9 (a) (relating to national human rights institutions), 59 (relating to the draft health code) and 73 (relating to the school optimization policy) above. 82. The Committee requests the State party to submit its fourth periodic report, to be prepared in accordance with the reporting guidelines adopted by the Committee in 2008 (E/C.12/2008/2), by 31 October 2022. In addition, it invites the State party to update its common core document, in accordance with the harmonized guidelines on reporting under the international human rights treaties (see HRI/GEN/2/Rev.6, chap. I). 12
