Zarif who has visited New York to attend the United Nations' High-Level Political Forum 2017 had earlier denied having any intentions to meet with the US officials.
Unconfirmed social media reports have suggested that the top Iranian diplomat was given the task of meeting Rex Tillerson.
Back in 2013, Zarif met former Secretary of State John Kerry during Iran’s nuclear talks with the world powers, marking the highest-level discussion in three decades between the two nations.
