context_page_description: The Belarusian-Ukrainian border is the state border between Belarus and Ukraine with a length of about 1,084 km. It starts from the triple junction with Poland to the west and stretches to the triple junction with Russia to the east. The tripoint border at the triple border junction of Belarus, Russia and Ukraine is marked in the form of a monument, while at the other border junction there is a river, the Western Bug that coincides with the border of Poland.
context_section_description: The modern state of the border is dated to World War I, when the Ukrainian People's Republic appeared on the map of the world in 1918.
  However, the border has historical roots. The border between the Grand Duchy of Lithuania and the Kingdom of Poland under the Union of Lublin was similar. It corresponded to administrative border of Brest-Litovsk and Minsk voivodeship on the Lithuanian side and Kiev, Volhynian, and Ruthenian voivodeships on the Polish side.
  After World War I and the treaty of Riga the western portion of the border roughly coincided with administrative border of the Polesia and Volyn provinces of the interwar Polish Republic, and the eastern portion coincided with the border between the Soviet republics of Belarus and Ukraine.
  At first, the border between both Soviet republics was recognized by the Treaty between the Ukrainian SSR and the Belarusian SSR from December 12, 1990.
  The status of the state border with Ukraine was given by the Supreme Soviet of Belarus of 11 June 1993, but there is an international agreement between Belarus and Ukraine, in which they mutually recognize the border BSSR and USSR recognized in 1990.
  To date, the border is governed by the Agreement between Belarus and Ukraine on friendship, good neighborliness and cooperation of 17 June 1995, the Treaty on the State Border between Belarus and Ukraine on 12 May 1997 in the same year was ratified by the Verkhovna Rada of Ukraine, and in 2010 the National Assembly of Belarus, but the parties still have not exchanged instruments of ratification.
  According to Chairman of the State Border Committee of Belarus, Igor Raczkowski, work on border demarcation may continue for up to 10 years and require 51 billion rubles.
  Demarcation of the border began with the 13 November 2013 inauguration of the first border sign at the place where the borders of Ukraine, Belarus and Russia meet.
  Following the Chernobyl disaster in 1986, a big portion of the border lies with the so-called Chernobyl Exclusion Zone (Ukrainian side) and Polesie State Radioecological Reserve (Belarusian side). The Chernobyl Exclusion Zone in Ukraine is governed by the Ministry of Ecology and Natural Resources through its special agency. The area does not have adequate infrastructure for border crossing which is conducted in the area under special authority due to contamination. The exclusion zone has its own checkpoints. The Chernihiv–Ovruch railway runs along the border on the Ukrainian side, connecting the abandoned Chernobyl Nuclear Power Station with the city of Slavutych. The tracks cross the border twice.
