Putin's comments follow a rocky period in U.S.-Russia relations, which have been undermined by disagreements over issues such as Ukraine and Syria. Putin reiterated criticism of what he said was the misguided role of the United States in Ukraine's affairs and said he opposed what he cast as U.S. efforts to prevent Russia repairing its relations with the European Union. But he had some positive words too. "America is a great power - today probably the only superpower. We accept that," Putin said at the St Petersburg International Economic Forum. "We want to and are ready to work with the United States."
