"We have received this calmly and know that sooner or later contacts will be resumed," Putin's top foreign policy aide Yury Ushakov said, quoted by Russian news agencies. "How would we retaliate? We said we were disappointed but emphasised the invitation remains in force."
Obama is still coming to Saint Petersburg for the September 5-6 G20 summit but Ushakov said no bilateral meeting with Putin is currently planned at this event.
