Iran said Tuesday there was a "historic" chance to resolve the nuclear issue if different approaches are adopted,  ahead of a much-anticipated meeting of world powers at the United Nations.

"We have a historic opportunity to resolve the nuclear issue," if world powers adjust to the "new Iranian approach," Foreign Minister Mohammad Javad Zarif said in a tweet from New York, where he is attending the UN General Assembly.

His comments came a day after he met EU foreign policy chief Catherine Ashton in New York to discuss restarting nuclear talks with the so-called P5+1 group -- the United States, Britain, France, China and Russia plus Germany.

Zarif will join counterparts from the P5+1, including US Secretary of State John Kerry, at the UN headquarters on Thursday for the first-ever US-Iranian nuclear talks at the ministerial level.
