WASHINGTON (AP) -- It will be President Barack Obama and Russian President Vladimir Putin's first meeting since Putin returned to Russia's top job.
Monday in Mexico City, each leader will try to claim leverage in a mutually dependent but volatile relationship.
Obama needs Russia to help, or at least not hurt, U.S. foreign policy aims in the Mideast and Afghanistan.
Putin needs the United States as a foil for his argument that Russia doesn't get its due as a great power.
Obama and Putin are set to meet on the sidelines of the Group of 20 economic gathering in Mexico that will otherwise focus largely on the European economic crisis.
