MOSCOW, May 27 (Xinhua) -- The Russian government has approved the new strategic arms reduction treaty (START) and handed it over to Russian President Dmitry Medvedev for ratification, said the government on its website on Thursday. Moscow and Washington signed the new START document in April. Under the new treaty, the warheads held by the two nuclear superpowers will be reduced to 1,500, about 30 percent lower than the previous treaty's limitation. Strategic offensive weapons will be based solely on the national territories of Russia and the United States. The widely hailed new pact is conducive to easing frustrated U. S.-Russian ties and pushing forward nuclear disarmament and the non-proliferation process on a global scale. Earlier on Thursday, head of Russian Federation Council's International Committee Mikhail Margelov voiced confidence that the U.S. Congress was able to finish the ratification before its August recess, despite the fact that such ratifying process was not easy.
