Kazakhstan–Russia border
International border / From Wikipedia, the free encyclopedia
The Kazakhstan–Russia border (Russian: Казахстанско-российская граница, Kazakh: Қазақстан-Ресей шекарасы) is the 7,644-kilometre (4,750 mi) international border between the Republic of Kazakhstan and the Russian Federation.[1] It is the longest continuous international border in the world and the second longest by total length, after the Canada–United States border.[2] It is in the same location as the former administrative-territorial border between the Kazakh Soviet Socialist Republic and the Russian Soviet Federative Socialist Republic.
