Iran's foreign minister will meet his United States counterpart for the first time on Thursday to hold talks over the Tehran's nuclear programme at the United Nations headquarters.
Secretary of State John Kerry said he will meet Mohammad Javad Zarif at the UN meeting as Iran called for easing out international sanctions over its uranium enrichment, News.com.au reports.
U.S. and its allies believe Tehran wants to build its capability for making nuclear bombs.
However, Rowhani denied all such claims in a U.S. television interview last week.
The White House said it was not ruling out a meeting between President Barack Obama and his Iranian counterpart Hassan Rowhani on the sidelines of this week's UN General Assembly.
