The Iranian delegation stated that leaving New York was a prearranged trip and that the U.S. side had been informed in advance.

Iran's Permanent Mission to the United Nations announced on September 30 that the Iranian delegation left New York on the evening of September 28, and that this travel arrangement had been communicated to the U.S. Department of State in advance on September 17. Having gained nothing, the U.S. Department of State instead spread baseless and worthless claims. According to U.S. sources on September 30, during the U.S.-Iran talks on September 28, neither side was willing to make concessions, and the negotiations reached a deadlock. Subsequently, U.S. Secretary of State Rubio demanded that the Iranian delegation leave the United States immediately. According to U.S. commentary, this move was "a very unusual diplomatic rebuke, exposing the deep-rooted distrust between the two countries."
