The five permanent members of the UN Security Council have agreed on a draft resolution giving Iran until the end of next month to suspend uranium enrichment.
The draft was circulated to the full 15 members of the Council and could be voted on as early as Monday.
Russia's envoy, Vitaly Churkin, said the draft did not threaten sanctions and would encourage Iran to resume dialogue.
But the US ambassador to the UN, John Bolton, said the Council would consider sanctions against Iran if it did not comply with the deadline.
The draft resolution was negotiated over the past two weeks by Germany and the five permanent Council members - Britain, China, France, Russia, the United States.
