International Atomic Energy Agency (IAEA) Director General Rafael Grossi returned to Vienna today after a trip on Friday to Tehran, where he came to an agreement with Iranian authorities establishing a timeline to complete inspections there. Meanwhile negotiations in Vienna to revive the 2015 Joint Comprehensive Plan of Action (JCPOA) nuclear pact with Iran were under threat by new Russian demands for guarantees that its trade interests in Iran upon implementation of the JPCOA will not be threatened by sanctions against Russia imposed by Western powers. In remarks at a press conference today about his discussions with Iran's atomic energy chief Mohammad Eslami, Director Grossi said, "We had a very intense day," and said that the aim is to conclude a final agreement between Iran and the IAEA by June, but added, "There is no pre-defined outcome." "The safeguard issues will not be resolved politically because I will not go for that," said Director Grossi. "Politically I suppose you mean we decide to solve them because somebody is putting pressure on me or somebody is saying you should close this. This is not going to happen." He said a joint statement issued by him and Mr. Eslami dismisses concerns that the outcome of the agreement will be determined by political pressures. "We have to be left alone in our professional work," he said, adding, "No politics here."
