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.
Post-Soviet transition in Ukraine
Between 1990 and 1991, several republics of the Soviet Union proclaimed their state sovereignty and then announced their independence. On July 16, 1990, the Ukrainian SSR's parliament issued its 12th legislation proclaiming the sovereignty of Ukraine's territory and the country eventually declared its independence on August 24, 1991. The declaration was then confirmed by the results of the referendum on December 1 later that year, where 90,3 % of voters were in favor of independence. The same day, Leonid Kravchuk, head of the Supreme Council of Ukraine, was elected as the country's first president. Following his election, an economic then political crisis developed and Kravchuk organized another presidential election as a response.
