“The Prime Minister and the Secretary General emphasized the importance of Russia not closing the door to dialogue, noting that the only possible way forward for Russia is to defuse tensions and engage in constructive discussions,” RIA Novosti quoted the British Prime Minister’s office as saying.

Earlier, Stoltenberg said that the alliance is ready to "put on the negotiating table" with Russia its specific security proposals for further discussion with Moscow.

In turn, Russian Foreign Minister Sergei Lavrov said that Moscow is expecting a reaction from the United States to proposals for security guarantees within a week.
