Another major source of disagreement is the issue of return of internally displaced persons (IDPs) and refugees, mostly ethnic Georgians, which the Abkhaz and South Ossetian representatives, with Russian backing, reject to discuss as long as Georgia is able to secure the yearly resolutions on IDPs at the UN General Assembly. Among topics touched upon the talks are those related to language of instruction in schools in predominantly ethnic Georgian areas of Abkhazia (such as the Gali district) as well as freedom of movement and mobility, missing persons, environmental and cultural heritage.[1]
