A/HRC/37/64 information on revoked and downsized concessions. This tool will serve as a basis for advocacy by NGOs and affected communities to reclaim their land. OHCHR also supported Open Development Cambodia in designing, validating and launching an interactive map of existing social land concessions. 47. OHCHR continued to expand its focus on business and human rights, working directly with national and subnational authorities, civil society organizations, community representatives and business actors to increase their understanding of the Guiding Principles on Business and Human Rights and their application in Cambodia. In partnership with the Cambodian Corporate Social Responsibility Platform, the NGO Forum on Cambodia and the Cambodian Human Rights and Development Association (ADHOC), OHCHR organized and delivered five training sessions and peer-to-peer discussions among private companies on the adoption and implementation of due diligence policies in Cambodia that were attended by more than 120 representatives of private businesses, local authorities, human rights defenders and community activists. In addition, OHCHR aired six live interactive radio talk shows on related themes with a variety of guest speakers from grassroots associations, national and international NGOs, Government, United Nations agencies and businesses, and individual experts. However, the radio broadcast of the talk shows was prevented owing to the fact that the licence of the partner’s broadcasting radio station had been revoked. Until new relays were found, the radio programme could continue only online, which restricted the audience to those who had access to the Internet. 48. OHCHR registered the adverse impact of the land titling process on indigenous and other communities who claim to have lost land due to land disputes or inconsistent implementation of government policies. OHCHR received petitions from individuals and groups who sought its intervention and legal advice on their disputes and concerns. It conducted field visits to ascertain facts, engaged with the relevant authorities, facilitated dialogue among the parties, monitored the work of dispute resolution mechanisms and provided legal and procedural advice to communities and the civil society organizations supporting them. VI. Supporting engagement with the international human rights mechanisms 49. OHCHR assisted the Special Rapporteur on the situation of human rights in Cambodia with preparations for a visit that the Special Rapporteur had requested to undertake in December. In the absence of a response from the Government, the Special Rapporteur subsequently requested that the visit take place in March 2018. 50. The Government has yet to submit overdue reports to the Committee on Economic, Social and Cultural Rights, the Committee on the Elimination of Racial Discrimination, the Committee on the Rights of Persons with Disabilities and the Committee on Enforced Disappearances, as well as its response to the list of issues of the Committee against Torture. OHCHR continued its technical support to the Cambodian Human Rights Committee, the Disability Action Council, the Ministry of Interior and the Cambodian National Council on Children for monitoring progress under the international human rights treaties. It also provided assistance to civil society organizations on engaging with the United Nations human rights mechanisms. 51. In this regard, with support from the OHCHR treaty body capacity-building programme, the Office conducted two training sessions with the Cambodian Human Rights Committee, with the participation of representatives of ministries and other institutions responsible for implementing treaty body recommendations, to increase the capacity of officials involved in drafting reports to treaty bodies. To continue strengthening the implementation of the Convention on the Rights of Persons with Disabilities at the local level, OHCHR supported training by the Disability Action Council of its local officials in Koh Kong Province in November. 8
