Russian President Vladimir Putin says the United States has ignored Moscow’s key concerns in its response to Russian demands for legally binding security guarantees aimed at easing tensions with the West over Ukraine.

Russia says talks with the West over the situation around Ukraine have hit a “dead end,” and that there is no reason to hold a new round of negotiations.

Russia says it does not understand the US criticism over Moscow’s troop deployment within its own territorial jurisdiction, while the presence of American troops in Europe does not cause any jitters.

NATO warns Moscow to brace for conflict with the military alliance if it does not abandon its “belligerent foreign policy” and cooperate with the West amid soaring tensions.

The foreign minister said the talks would take place immediately after Russia's New Year holidays.

Moscow is considering the NATO’s proposal to begin talks on Russia’s security concerns on January 12, TASS reports.
