Russia has been hit by lower oil prices and by Western sanctions over its role in the Ukraine crisis. Its rouble currency fell sharply against the dollar in 2014 and has yet to recover.

U.S. was keeping the European Union countries on a 'short leash' by forcing them to impose anti-Russia sanctions.

‘Rosneft and BP signed final binding agreements for Rosneft’s sale to BP of a 20 per cent share of Taas-Yuryakh Neftegazodobycha (Taas), creating a new joint venture in East Siberia. The document was signed by Rosneft Management Board Chairman Igor Sechin and President of BP Russia David Campbell’ BP said, reporting one of the most relevant deals. During the first day of the international conference, Gazprom agreed to build a new pipeline to Germany under the Baltic Sea with Germany’s E.ON, Anglo-Dutch Shell, and Austria’s OMV.

BP could be close to a $700 million deal with Russia’s Rosneft for a 20% stake in a Siberian oilfield, the company led by Igor Sechin further showed how national companies can cope with sanctions, maintaining ties with Western companies and progressively switching to Asian markets.

"Uncertainty is the rule of the game in this industry," the head of France's Total Patrick Pouyanne said this month. "We are in the long-term business. This is why at Total we are keen to maintain our commitment to Russia."

Europe’s biggest oil groups are extending business deals with their Russian energy partners despite this month’s EU vote to continue imposing sanctions, highlighting how western companies are learning to live with the restrictions placed on Moscow.

The US and EU sanctions are primarily targeted at the country's oil industry, for very obvious reasons. Russia provides about 30% of Europe's gas, so it's simply not in the EU's interests to compromise Gazprom's ability to produce and export gas.

Through a series of deals with Rosneft, the Russian state-controlled oil company, Trafigura exported almost 9m barrels of crude in April, worth more than $500m, according to port data compiled by Nefte Compass, an industry publication.

Russia is developing non-dollar financing and ties with China in the face of U.S. and EU sanctions

Sanctions have stopped Russia’s state-controlled oil group Rosneft expanding its trading operations, the company revealed on Tuesday, preventing it from capitalising on one of the main revenue sources tapped by western rivals during the oil price rout.
