"I think that the Geneva format of talks could form the basis for further consultations, but only if they are focused on results," Klimkin said.
He also commented on a statement by Russian presidential spokesman Dmitry Peskov that Russia needed firm guarantees that Ukraine would never join NATO.
"Peskov can say whatever he wants - that's his work as a press secretary," Klimkin said.
"Russia has committed acts of aggression against Ukraine, and this refers not only to the Donbas region - first of all it concerns the annexation and occupation of the Crimea, which started the current situation," he added.
As reported earlier, Russian Foreign Minister Sergei Lavrov has said the "Geneva" format of talks is no longer needed.
