Russia's foreign minister Tuesday reaffirmed Moscow's concern over U.S. plans to deploy missile defense sites in Europe, saying Russia would respond but would not enter a new arms race, The Associated Press reported. «Russia will respond to emerging threats to its national security in a carefully weighed, adequate way, and won't allow anyone to draw it into a new confrontation, a new arms race,» Russia's Foreign Minister Sergey Lavrov said Tuesday in a speech at a Moscow university. Lavrov said Tuesday that Russia also was concerned about NATO forces' deployment near its borders and the alliance's refusal to ratify a modified version of the 1990 Conventional Forces in Europe (CFE) Treaty regulating the deployment of tank, aircraft and other heavy non-nuclear weapons around the continent.
