RosUkrEnergo

RosUkrEnergo is a Swiss-registered venture company that transports natural gas from Turkmenistan to East European countries. 50% of the company is owned by Gazprom, through its daughter Swiss-registered Rosgas Holding A.G., and another 50% by Swiss-registered private company Centragas Holding A.G., acting on behalf of a consortium of GDF Group owned by Dmytro Firtash and Ivan Fursin.

Before 2009 Russia–Ukraine gas dispute, it was the sole importer of natural gas from Gazprom reselling it to Naftogaz Ukrainy.

The company was created in July 2004 in a deal by former Ukrainian President Leonid Kuchma and his Russian counterpart Vladimir Putin to replace Eural Trans Gas. Until 2006 the company acted as a middleman between Turkmenistan and Ukraine. The company also sells Turkmenistan gas to Poland. Due to an agreement between Gazprom and Naftogaz, from 2006 till January 2009 the company supplied all of Ukraine's natural gas imports from Russia and other Central Asian countries, in addition to Turkmenistan. On October 24, 2008 Gazprom and Ukraine's national energy company Naftogaz signed a long-term cooperation deal in which was stated that Ukraine will receive Russian natural gas directly from Gazprom and Naftogaz will be the sole importer of Russian natural gas.

After weeks of disputes the head of Gazprom Alexei Miller and the head of Naftohaz Ukrainy Oleh Dubyna signed the 10-year agreement on natural gas supplies to Ukraine for the period of 2009-2019 on 19 January 2009. It was agreed that RosUkrEnergo will no longer supply all of Ukraine's natural gas imports from Russia and other Central Asian countries. A claim of a $600 million debt of Naftohaz to RosUkrEnergo was also dropped.
