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.
Poland–Ukraine relations
Ukraine and Poland are respectively, the second and third largest Slavic countries, after Russia. The two countries share a border of about 529 km. Poland's acceptance of the Schengen Agreement created problems with the Ukrainian border traffic. On July 1, 2009, an agreement on local border traffic between the two countries came into effect, which enables Ukrainian citizens living in border regions to cross the Polish frontier according to a liberalized procedure.
