"Naturally, we will be glad to welcome the initiative of reviving the logic of dialogue and cooperation," he said. "We are ready to welcome our partners' moves."
The spokesman said that Russia was not the first to impose sanctions or fold bilateral dialogue and "can only regret that Washington started it all."
Washington has introduced several rounds of economic sanctions against Russia, blaming Moscow for meddling in Ukraine's internal affairs.
Moscow in turn has repeatedly denied any involvement in the Ukrainian conflict.
Russia has also played an important role in the Ukraine reconciliation efforts, brokering a ceasefire agreement between Kiev and pro-independence militias in February, along with France and Germany.
