Urengoy–Pomary–Uzhhorod pipeline

The Urengoy–Pomary–Uzhhorod pipeline (also known as the Bratstvo pipeline, Brotherhood pipeline, West-Siberian Pipeline, or Trans-Siberian Pipeline) was one of Russia's main natural gas export pipelines, partially owned and operated by Ukraine. It was part of the "gas in exchange for pipes program", and the Soviet-controlled bank "Ost-West Handelsbank" was opened in Frankfurt on 1 March 1973 to support the project.
