Washington (AFP) Feb 1, 2011 President Barack Obama will formally sign ratification papers for a new Russia-US disarmament treaty on Wednesday, which slashes existing warhead ceilings by 30 percent over the next 10 years. Officials said Obama will make the ceremonial gesture in the Oval Office, before the milestone pact comes into force on February 5 at a ceremony in Munich attended by the two nations' top diplomats.
Russian President Dmitry Medvedev signed the new START agreement's ratification on Friday after the Russian parliament passed the pact, which was endorsed by the US Senate last month.
The replacement for the Strategic Arms Reduction Treaty (START) deal enters into force the moment the two sides swap their respective "instruments of ratification."
Russian diplomatic sources said the ceremony will be held during the February 4-6 Munich Security Conference -- an annual gathering of some of the world's most senior defense officials and experts.
US Secretary of State Hillary Clinton and Russian Foreign Minister Sergei Lavrov are expected to preside.
The new START sets the lower warhead ceiling and limits each side to 700 deployed long-range missiles and heavy bombers, and forms one of the most significant foreign policy successes of Obama's presidency so far.
