Russia has not created environment for Ukraine diplomacy - U.S.

Russia's bloodless seizure of the Crimea region of Ukraine has brought U.S.-Russian relations to one of their lowest points since the Cold War, with the United States searching for a way to keep Russia from annexing Crimea and its Russian naval base.
