During a ceremony Saturday in Munich, Germany, U.S. Secretary of State Hillary Clinton and Russian Foreign Minister Sergei Lavrov exchanged ratification documents, formally enacting the new treaty. The ceremony took place on the sidelines of a security conference being held in Munich. Clinton has called the agreement "the kind of clear-eyed cooperation that is in everyone's interest."Â Lavrov said the treaty will enhance international stability. The new treaty restricts each nation to 1,550 strategic nuclear warheads, a 30 percent reduction from limits set in 2002. U.S. President Barack Obama and Russian President Dmitry Medvedev signed the treaty last April to replace an arms control pact signed in the waning days of the Cold War in 1991. U.N. Secretary-General Ban Ki-Moon praised both Presidents Obama and Medvedev for showing leadership on the nuclear arms reduction issue. The new START agreement was approved by the U.S. Senate in December and passed the Russian parliament last month. Some information for this report was provided by AFP, AP and Reuters. .
