Minorities in Ukraine
Minorities in Ukraine form 22.2 percent of the country's population as of 2001. Large ethnic Russian, Belarusian, Crimean Tatar, Bulgarian, Hungarian, and Romanian minorities exist in Ukraine, and Romania and Hungary have striven for the minority rights of the minorities they respectively represent. Ukraine also has a small number of Poles, Jews, Armenians, Roma and other nationalities.

Prime Minister of Hungary Viktor Orbán has threatened to veto Ukraine's process of EU accession numerous times over minority rights issues.
