Deputy Foreign Minister for Legal and International Affairs Abbas Araqchi will leave Tehran for Vienna Monday night for talks with the Head of the International Atomic Energy Agency (IAEA) Yukia Amano, IRNA reported.
He is to continue talks with the international watchdog on nuclear issues.
Cooperation between Iran and the IAEA on ways of enhancing and accelerating relations will be at the center of their dialogue.
Amano met with Iran's Foreign Minister Mohammad Javad Zarif last month at the sideline of a security meeting in Munich.
Araqchi has been in Geneva since Friday to hold talks with the US delegation on nuclear issues.
