Speaking to reporters on the sidelines of the cabinet's weekly session in Tehran, Mohammad Baqer Nobakht confirmed that President Rouhani will travel to New York to attend the 69th session of the UN General Assembly.
The spokesman, however, stressed that the president has not made any plan so far for a meeting with his US counterpart Barack Obama.
Nobakht added that details of President Rouhani's UN trip will be unveiled later in a press conference.
It will be Rouhani’s second presence in the UN since taking office in August 2013.
What has focused further attention on Iran in this year’s UN General Assembly is the nuclear talks that Tehran will hold with six world powers on the sidelines of the event.
A fresh round of nuclear negotiations between Iran and the Group 5+1 (Russia, China, the US, Britain, France and Germany) will commence in New York on September 19.
The talks will kick off with a meeting between Foreign Minister Zarif and the outgoing European Union Foreign Policy Chief Catherine Ashton, who coordinates diplomacy with Iran on behalf of the six nations.
Last November, the two sides signed an interim deal in Geneva, which took effect on January 20 and expired six months later on July 20. In July, Tehran and the six countries agreed to extend negotiations until November 24 after they failed to reach common ground on a number of key issues.
