Ukraine is on the continent of Europe. It is in the eastern part of that continent, and most of its southern border is the coast of the Black Sea.
To the east, Russia borders Ukraine; in fact, until Dec. 1, 1991, Ukraine was a part of the Russian-dominated Soviet Union. According to Encyclopædia Britannica, this close proximity has resulted in a long relationship between the countries that is sometimes peaceful and sometimes antagonistic. North of Ukraine lies Belarus, and Ukraine's western border touches Poland, Slovakia and Hungary. Romania and Moldova lie along Ukraine's southwestern border. In 2014, Russia annexed Ukraine's Crimean Peninsula, putting a Russian frontier on Ukraine's southern side as well. As of 2014, Ukraine is attempting to create closer ties with countries in the central and western portions of its continent and to move away from its historical connections with Russia.
