accused Russia of giving Russian passports to the population in Crimea, and described it as a "real problem", given Russia's declared policy of military intervention abroad to protect Russian citizens. On 24 August 2009, anti-Ukrainian demonstrations were held in Crimea by ethnic Russian residents. Sergei Tsekov (of the Russian Bloc and then deputy speaker of the Crimean parliament) said then that he hoped that Russia would treat Crimea the same way as it had treated South Ossetia and Abkhazia. Crimea is populated by an ethnic Russian majority and a minority of both ethnic Ukrainians and Crimean Tatars, and thus demographically possessed one of Ukraine's largest ethnically Russian populations.

The Security Service of Ukraine (SBU) responded by opening a criminal case to investigate the possible "subversion" of Ukraine's territorial integrity. On 20 February 2014, during a visit to Moscow, Chairman of the Supreme Council of Crimea Vladimir Konstantinov stated that the 1954 transfer of Crimea from the Russian Soviet Federative Socialist Republic to the Ukrainian Soviet Socialist
