US Vice President Joe Biden says it's time to repair the rift in relations between the U.S. and Russia, AP reported. Biden told a gathering of world leaders here Saturday that NATO and Russia should cooperate to defeat the Taliban and al-Qaida. But he warns the United States will continue to have differences with Moscow, including opposition to its efforts to carve out independent states in Georgia. Biden's comments come just days after the former Soviet republic of Kyrgyzstan announced it will shut down American access to the Manas air base, which the U.S. uses to resupply troops in Afghanistan.
