Head of the Atomic Energy Organization of Iran (AEOI) Ali Akbar Salehi expressed optimism about the settlement of differences between Tehran and the world powers, saying that the important point is both sides’ resolve to this end.

The most important factor under the current conditions is both sides’ will to resolve the matter, Salehi said in an interview with Iran’s state-run TV on Wednesday.

He said that both sides have stepped forth with a resolute will to resolve the problem, and it is hoped that the remainder of the path, too, would be paved the same way.

On Sunday, Iran and the six world powers finalized an agreement on ways to implement the Geneva nuclear deal, which the two sides struck in the Swiss city of Geneva on November 24, 2013, from January 20.

On November 24, Iran and the world powers sealed a six-month Joint Plan of Action to lay the groundwork for the full resolution of the West’s decade-old dispute with Iran over its nuclear energy program. In exchange for Tehran’s confidence-building bid to limit certain aspects of its nuclear activities, the Sextet of world powers agreed to lift some of the existing sanctions against Tehran and continue talks with the country to settle all problems between the two sides.
