“In fact, neither on the expansion of NATO, nor on the non-deployment of strike forces on Ukrainian territory, nor on the return to the configuration of the alliance’s forces to the state of 1997, when Russia’s founding act of NATO was signed, did we receive an answer in essence,” he said.

Earlier it was reported that Russian leader Vladimir Putin, in a conversation with US President Joe Biden, noted that the Russian side had completed an interagency study of possible actions in the light of NATO and the US response to Russia's proposals for security guarantees.

On January 27, Dmitry Peskov, the press secretary of the Russian head of state, said that Russia would not delay responding to the response to the United States on security guarantees.
