Russia said on Sunday it would not make concessions under U.S. pressure and warned that this week's talks on the Ukraine crisis might end early, while Washington said no breakthroughs were expected and progress depended on de-escalation from Moscow.
The hard line from Moscow underscored the fragile prospects for negotiations that Washington hopes will avert the danger of a new Russian invasion of Ukraine, at the tensest point in U.S.-Russia relations since the Cold War ended three decades ago.
Talks begin on Monday in Geneva before moving to Brussels and Vienna, but the state-owned RIA news agency quoted Deputy Foreign Minister Sergei Ryabkov as saying it was entirely possible the diplomacy could end after a single meeting.
