According to accounts by former United Nations diplomat Giandomenico Picco, Zarif contributed to negotiations intended to facilitate the release of hostages and reduce tensions.
These experiences introduced him to the challenges of negotiating between governments with deeply conflicting political interests.
They also reinforced his belief that diplomatic communication could remain useful even when formal relations between countries were severely damaged.
Throughout the following years, Zarif developed expertise in multilateral diplomacy, international law, disarmament, and conflict resolution.
He occupied various positions within Iran’s Ministry of Foreign Affairs, including responsibilities involving legal and international affairs.
His experience at the United Nations helped establish his reputation as a knowledgeable diplomat capable of communicating effectively with representatives from different political and cultural backgrounds.
