E/C.12/MNG/CO/4 access to schools and their facilities, and the allocation of sufficient financial resources. Cultural rights 30. The Committee is concerned about the inadequate implementation of the National Policy for Arts and Culture (2011), mainly owing to the limited allocation of resources. It is also concerned that efforts to preserve the cultural heritage of the State party are not sufficient despite the fact that measures have been taken to address the issue (art. 15). The Committee recommends that the State party allocate the resources necessary for the effective implementation of the National Policy for Arts and Culture. It is also requested to step up its efforts and increase its investment in preserving the cultural heritage, including by monitoring and ensuring the strict implementation of the Law on Protection of Cultural Heritage (2014). D. Other recommendations 31. The Committee recommends that the State party ratify the International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families and the Optional Protocol to the Convention on the Rights of the Child on a communications procedure. 32. The Committee recommends that the State party step up its efforts in raising the awareness of the members of the judiciary, the lawyers and the rights holders, of the International Covenant on Economic, Social and Cultural Rights and its Optional Protocol, as well as the justiciability of those rights. The Committee draws the State party’s attention to its general comment No. 9 (1998) on the domestic application of the Covenant. 33. The Committee requests the State party to translate the present concluding observations into Mongolian and to disseminate them widely at all levels of society, particularly among parliamentarians, public officials, judicial authorities and rights holders, and to inform the Committee in its next periodic report on the steps taken to implement them. It also encourages the State party to engage non-governmental organizations and other members of civil society in the process of implementing the present concluding observations, prior to the submission of its next periodic report. 34. The Committee requests the State party to submit its fifth periodic report by 30 June 2020, and invites the State party to update its common core document, as required, in accordance with the harmonized guidelines on reporting under the international human rights treaties (HRI/GEN/2/Rev.6, chap. I). 10
