The European Union is due to hold a fresh round of talks with Russia and Ukraine in Berlin on Friday in a bid to settle an ongoing dispute over gas deliveries.
Europe gets more than 30 percent of its gas from Russia, with half of that transiting through Ukraine, but in June Moscow cut off supplies intended for Kiev amid a bitter price dispute.
For now, gas is continuing to flow as normal through Ukraine into the EU, but Russia has warned there was a high risk of disruption of deliveries to Europe this winter as international tensions remain high over the Ukraine crisis.
Europe does not have the infrastructure to accept LNG in major quantities.
