He was later shown visiting the president of Armenia, indicating that he is back to work.Iran's president rejected the resignation of his foreign minister on Wednesday, throwing his full support behind the diplomat who negotiated the country's nuclear deal with world powers as both men face growing pressure from hard-liners as the accord unravels under American pressure.
(...) "Since I consider you in the front line of resistance against broad pressures by the U.S., I consider acceptance of your resignation against the expedience of the country and I do not agree with it," Rouhani reportedly told Zarif.
His resignation threat was believed to have been sparked by attempts by hard liners in Iran who want to get rid of him so they can roll back the nuclear deal and resume building a nuclear arsenal. Zarif is closely associated with the agreement with Western countries to limit nuclear activities in return for a removal of trade sanctions. US attempts to undermine the deal have undermined moderate factions in Iran and strengthened the position of hard liners.The 59-year-old diplomat later was shown on state television at an event with visiting Armenian Prime Minister Nikol Pashinyan, signalling his return to work.
