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.
Ukraine–European Union relations
In a November 2014 poll by Rating joining the EU was supported by all but 2 Oblasts of Ukraine (provinces); in Luhansk Oblast and Donetsk Oblast (an area known as Donbass) people preferred Ukraine's accession to the Eurasian Customs Union. Traditionally Western Ukraine is found to be generally more enthusiastic about EU membership than Eastern Ukraine. In July 2012 and in May 2014 residents of West Ukraine (74% in July 2012 and 81% in May 2014), Central Ukraine (59% and 64%) and North Ukraine (56% and 71%) were the biggest supporters for EU membership. A June 2013 poll, on behalf of Deutsche Welle, found that 52% of Eastern Ukraine was in favor of joining the EU. But in a poll by ComRes (for CNN) in May 2014 only 19% of Eastern Ukraine considered Ukraine joining the European Union "Good". The May 2014 ComRes poll found out that in the 3 most eastern Oblasts of Ukraine (provinces), Kharkiv Oblast, Donetsk Oblast and Luhansk Oblast, 37% favored an alliance with Russia, 14% backed an alliance with the European Union and 49% stated Ukraine would be better off if it did not ally with either.
