Araghchi made the remarks after a meeting with the Director-General of the International Atomic Energy Agency on Thursday night.

“Iran's national interests are the only priority for the negotiating delegation,” he emphasized.

Noting that it would be the fourth round of Vienna talks, he said the Iranian team would follow the process started in the previous three rounds.

He continued as follows: “As I said before, we are on a specified path about which there are fortunately agreements, but there are serious obstacles in the way as well. We have a long way ahead the timing of which is impossible to imagine or predict, and it would be unrealistic if we want to enter into the timing discussion.”

He also underlined that his team was trying to do this as soon as possible, but they would not act on haste unnecessarily to reduce the accuracy.
