Russia has condemned efforts by former Soviet nations such as Ukraine and Georgia to join NATO. Foreign Minister Serguei Lavrov said such a move would cause a “colossal geopolitical upset”.“We are considering all the possible consequences of such a step in terms of Russia’s national security interests, as well as our economic interests and our relations with these countries,” he told deputies in the lower house of parliament on Wednesday. Russian lawmakers have appealed to their Ukrainian counterparts in a document confirming the Duma’s “extremely negative attitude” to Kiev’s plans to join NATO. They say such a move would have “very negative consequences” on relations between the two countries. The Russian reaction follows widespread protests against planned exercises with NATO due to start next month on the Ukrainian peninsula of Crimea where Russia’s Black Sea fleet is based.
