The Iran Six will meet this week in New York, U.S. State Secretary Hillary Clinton told journalists on her way to Hawaii on Monday.
A diplomatic source told RIA Novosti the meeting would take place on Saturday.
A meeting of the Iran Six - Britain, China, France, Germany, Russia and the United States - was scheduled for December 22, but was canceled by request of China.
The Iran Six have been trying to persuade Tehran to halt uranium enrichment it says it needs for electricity generation for economic and diplomatic incentives. Iran Six envoys last met in Geneva on October 1.
Iran, which is already under three sets of United Nations sanctions for refusing to halt uranium enrichment, recently announced plans to build 10 new uranium enrichment facilities. Western powers suspect it of pursuing an atomic weapons program.
Britain's envoy to the UN Mark Lyall Grant said in late December that the UN Security Council could introduce new sanctions against Iran by late February unless Tehran accepts the Iran Six's offer on its controversial nuclear program.
