“It is not clear what is or is not the central demand of Russia,” he said.
According to the US Secretary of State, Russia has presented a number of proposals, some of which are "doomed to fail, such as closing the doors of NATO to new members."
“Other proposals, if they really contribute to strengthening security on a mutual basis, then we made it clear that we can discuss them,” he said.
Blinken also said that he was not bringing Russian Foreign Minister Sergei Lavrov to Geneva a written response to Russian proposals on security guarantees.
Blinken and Lavrov will meet on January 21 in Geneva.
