Russia’s foreign ministry currently sees no basis for resuming discussions on strategic stability and arms control with the United States, as reported by the Interfax news agency on Saturday, citing the deputy foreign minister of Russia.

Sergei Ryabkov indicated that Moscow and Washington are communicating regarding Ukraine through confidential military and political channels, according to Interfax.

He also expressed Russia’s willingness to consider proposals from U.S. President-elect Donald Trump aimed at addressing the crisis in Ukraine, while noting that a straightforward resolution is unlikely.

“We approach any suggestions from countries in this domain with great care, responsibility, and attention,” Ryabkov was quoted as saying by Interfax.

On Thursday, Russian President Vladimir Putin congratulated Trump on his election victory, commending him for his bravery during a July assassination attempt, and stated that Moscow is open to dialogue with Trump. He remarked that Trump’s statements about seeking to end the conflict deserve serious consideration.

Trump informed NBC that he had not communicated with Putin since his election victory, but expressed optimism, stating, “I think we’ll speak.”

Ryabkov indicated that the possibility of severing diplomatic ties with the United States remained on the table if Russia’s frozen assets were confiscated or if Washington intensified tensions regarding Ukraine.

Additionally, Ryabkov addressed Russia’s revised nuclear doctrine, noting that it would allow for the “nuclear option” to be considered in the event of a severe crisis in relations with the West and the ongoing situation in Ukraine, as reported by Interfax.

“This process will be completed. The president of the Russian Federation, as the supreme commander-in-chief, will certainly make decisions that will enhance the foundational concepts of our operations in this area,” Ryabkov stated to Interfax.

In September, Putin cautioned the West that under the proposed modifications to the doctrine, Russia could resort to nuclear weapons if attacked with conventional missiles and would regard any assault on it, backed by a nuclear power, as a collective attack.
