“I proceed from the fact that the formats for continuing the discussion of those red lines that our leadership spoke about in recent days, as well as the receipt by Russia of the most reliable legal legally binding security guarantees, are subject to further discussion,” RIA Novosti quoted him as saying.
He noted that "there is a whole series of platforms where these discussions can be held."
At the same time, Ryabkov added that at the moment "nothing has been decided."
Earlier, the Foreign Ministry said that Russia reserves the right to respond to the dangerous activity of the United States and NATO member countries along the perimeter of the Russian borders, including the flights of military aircraft and dangerous maneuvers of naval ships.
