Russia is not going to attack Ukraine, Russian Deputy Foreign Minister Sergei Ryabkov said, RIA Novosti reported.

"We do not intend to take any aggressive actions. We will not attack, attack or invade Ukraine," he said during a speech at the Valdai Club.

"We will not take any actions that will threaten Ukraine. We are only conducting exercises, regular movements of troops on our own territory," he also stressed.

Also an alternative to the so-called "security guarantees" for Russia in terms of not expanding NATO could be a legal commitment by the United States not to vote for Ukraine's accession.

Russian Deputy Foreign Minister Sergei Ryabkov said the West should reject the outcome of the 2008 Bucharest summit, when Ukraine and Georgia were promised membership in NATO.

"This should be ruled out, it should be replaced by the understanding that it will never happen. Or alternatively, if the U.S. makes unilateral commitments in a legally binding form that it will never vote for Ukraine and other countries to join NATO, we are willing to consider that option," Ryabkov said.
