Vilnius, Lithuania – With the Crimea crisis souring relations between Russia and the European Union, many European nations are increasingly concerned about their heavy reliance on Russia for natural gas.
Many European countries get a significant amount — in some cases all — of their natural gas from Russia, and they fear that as relations deteriorate over Ukraine, it could be just a matter of time before the supply is affected — either through disruptions to the supply routes that run through Ukraine or, as is considered more likely, the result of political moves from Moscow.
The E.U. and the United States are expected to announce the first round of sanctions against Russia on Monday.
According to the German newspaper Bild, the E.U. already has drawn up a list of high-level Russians who could be hit with travel bans and asset freezes. That list includes the chief executives of Russia's largest energy companies.
The fear is that Russia will respond by disrupting the flow of natural gas to its clients in Europe.
European leaders have been warning of their vulnerability for weeks. Last week, Poland's prime minister, Donald Tusk, said the dependence on Russian gas supplies would seriously hamper Europe's ability to respond if Russia moved beyond Crimea.
"We will not be able to efficiently fend off potential aggressive steps by Russia in the future, if so many European countries are dependent on Russian gas deliveries or wade into such dependence," he said.
Bulgaria's prime minister told his Parliament earlier this month that his country had enough natural gas for the next two months, but that natural gas use must be carefully managed in case of disruptions to their supply lines.
