Tehran said on Friday that a comprehensive nuclear agreement with the West remains possible before a November deadline, as long as world powers are sincere during upcoming talks.

Majid Takht-Ravanchi, deputy foreign minister for European and US affairs and a member of Iran's nuclear negotiations team, made the remarks during a meeting with Czech officials in Prague.

"As long as the P5+1 are sincere and they have a constructive approach, we can reach a good result before November 24," the official IRNA news agency quoted the top Iranian negotiator as saying.

Takht-Ravanchi was referring to the five permanent members of the UN Security Council (Britain, China, France, Russia, the United States) and Germany, with whom Iran has been negotiating since last year.

New talks between Iran and the P5+1 nations will start in New York on September 18, with outgoing European Union foreign policy chief Catherine Ashton chairing the discussions.  

The two sides struck an interim deal last November under which Iran agreed to curbs on some parts of its nuclear program in exchange for limited sanctions relief. However the talks later ran into difficulties and a July deadline for a final accord was missed. The discussions were extended until November 24.

The New York talks will be held on the sidelines of the UN General Assembly opening, with the US side being led by Under Secretary Wendy Sherman.
