Belarus–Ukraine relations
Belarus–Ukraine relations (, "Byelaruska-ŭkrainskiya adnosiny", , "Ukrains'ko-Bilorus'ki vidnosyny", , "Belorussko-ukrainskiye otnosheniya") are foreign relations between Belarus and Ukraine. Both countries were successively ruled by the Polish-Lithuanian Commonwealth, the Second Polish Republic, and ultimately, the Russian Empire. Prior to the 1991 breakup, both countries were part of the Soviet Union as the Belarusian SSR and Ukrainian SSR when they were the founding members of the United Nations in 1945. Being Slavic nations, both Belarus and Ukraine share closely related cultures and are predominantly inhabited by the East Slavic ethnic groups of Belarusians and Ukrainians respectively, along with a few Russians. Today, the two countries share an 891–km border.
Southern Ukraine
Noticeable cultural differences in the region (compared with the rest of Ukraine, except Eastern Ukraine) are more "positive views" of the Russian language and of Joseph Stalin and more "negative views" of Ukrainian nationalism. In the 1991 Ukrainian independence referendum, a lower percentage of the total electorate voted for independence in Eastern and Southern Ukraine than in the rest of the country.
In a poll conducted by Kyiv International Institute of Sociology in the first half of February 2014, 19.4% of those polled in Southern Ukraine believed "Ukraine and Russia must unite into a single state"; nationwide this percentage was 12.5.
