Upon the invitation of the UNESCO officers our Association sent the contribution to the project of Global Action Plan of the International Decade of Indigenous Languages. Such consultation regarding drafting this Plan on period 2022-2032 were organized by the UNESCO Secretariat of the Decade of Indigenous Languages. In ARC contribution we informed UNESCO on the linguistic discrimination of Crimean Tatars in the occupied Crimea and on danger of total disappearance of the Karaite and Krymchak languages. We informed UNESCO on steps done by Ukrainian authorities in this area, including adoption of the law on indigenous peoples and amendments to the educational and broadcasting legislation.
