High-level diplomatic efforts to resolve the crisis in Ukraine made little apparent headway at talks in Paris on Wednesday with Moscow and Washington at odds and Russia's foreign minister refusing to recognize his Ukrainian counterpart.

U.S. Secretary of State John Kerry said discussions would continue in the coming days in an attempt to stabilize the crisis and he expected to meet Russian Foreign Minister Sergey Lavrov again in Rome on Thursday.

"Don't assume that we did not have serious conversations which produced creative and appropriate ideas on how to resolve this, we have a number of ideas on the table," he said after talks with ministers from Ukraine, Russia, Britain and France.
