For his part, the Qatari foreign minister underlined the need for further activation of bilateral relations, praising Iran for its active participation in Doha Forum international conference.

Iran signed the nuclear deal, formally known as the Joint Comprehensive Plan of Action, with the world powers in July 2015.
