Russia's burgeoning economic power does not represent a threat to other countries, but the West has to get used to Moscow's growing influence in world affairs, a senior Russian official said Sunday. First Deputy Prime Minister Sergei Ivanov also told a gathering of the world's top defense officials that Russia would like to see a new multilateral approach to nuclear arms control to replace old US-Russian agreements. Ivanov said Russia expected to be among the world's five biggest economies by 2020 but that "we do not aim to buy the entire Old World with our petrodollars." "Getting richer, Russia will not pose a threat to the security of other countries. Yet our influence on global processes will continue to grow."
