A/HRC/33/27 68. During the period under review, OHCHR further expanded its work on advancing the rights of indigenous peoples at the country level, enhanced inter-agency cooperation and engaged more closely with multilateral development entities to produce tools and achieve sustainable results. Much of that work builds on the outcome document of the high-level plenary meeting of the General Assembly known as the World Conference on Indigenous Peoples, in which States committed themselves to developing national action plans with a view to achieving the ends of the United Nations Declaration on the Rights of Indigenous Peoples and to strengthening the mandate of the Expert Mechanism. OHCHR will support the development of such action plans, including by preparing a manual and by providing case-by-case advice. OHCHR will continue to support the work of members of the Inter-Agency Support Group on Indigenous Peoples’ Issues and others to promote system-wide follow-up to the outcome document. 69. The present report contains information on many achievements at the international level and some successes at the country level. Much remains to be done, however, to fill the gaps in national policies and strategies and to achieve full compliance with the Declaration and the outcome document. 15
