The Agreement on Customs Union between the Russian Federation and the Republic of Belarus (Соглашение о Таможенном союзе между Российской Федерацией и Республикой Беларусь от 6 января 1995 года) was concluded in Minsk on 6 January 1995 between the Government of the Russian Federation by Viktor Chernomyrdin and the Government of the Republic of Belarus by Sergey Ling in two original copies in the Russian and Belarusian languages, both texts being equally authentic. According to the website of the Eurasian Economic Union, “Applies to the extent not contradicting the Treaty on the Eurasian Economic Union of 29 May 2014”. The Depositaries are the Republic of Belarus and the Russian Federation.[5]
However, a customs union without a common external tariff is not a real customs union, so the full-scale launch of the customs union took place only on 1 January 2010. A 2004 International Monetary Fund publication noted that it was not a customs union (which requires a common external tariff) but a free trade area (as of 2004).[6]
The Union State of Russia and Belarus is described as the integration core within the Eurasian Economic Union and post-Soviet economic integration.[7][8][9]
