Russian natural gas producer Gazprom put Ukraine's total gas debt at almost $29.5 billion on Thursday, ratcheting up pressure in a gas pricing dispute with the country, which is fighting a pro-Moscow rebellion on its eastern outskirts.

OAO Rosneft may have to turn to competitors to buy natural gas and state aid to help honor a $50 billion contract it won away from OAO Novatek three years ago, according to two people with knowledge of the matter.

Russian energy company Gazprom has made it clear that it intends to move forward with the construction of the Turkish Stream natural gas pipeline as quickly as possible, whether or not the project can overcome political obstacles in Europe.

Naftogaz's role is the creation of an efficient gas market in Ukraine.

The crisis in Ukraine highlighted the need for Europe to tighten energy links among member states and cut its dependence on Russia, which supplies 27% of the bloc’s natural gas. To ensure that intergovernmental agreements with Russia don’t breach EU law, the regulator should vet their content during negotiations and not just before deals are adopted.

Britain's largest energy supplier Centrica (CNA.L) has signed new gas contracts with two of the world's largest producers, Russia's Gazprom and Norway's Statoil, reflecting the UK's growing dependence on gas imports as its production declines.

Gazprom has switched to the stage of building the offshore section of the Turkish Stream gas pipeline intended to bring Russian natural gas to Europe via Turkey, Gazprom CEO Alexey Miller said on Friday.

The United States, wading into the international efforts to shape Greece’s economic and geopolitical orientation, is pushing the leftist government in Athens to resist Russia’s energy overtures.

Russia’s gas giant Gazprom is ready to launch gas supplies to China via the so-called eastern corridor within 4 years, Deputy Chairman of Management Committee Alexander Medvedev said Wednesday.

Russian natural gas accounts for roughly a third of all foreign supplied natural gas coming into Europe. Russia’s biggest partner is Germany. In that state, Russia’s presence is on the upswing.
