According to Iranian Deputy Foreign Minister Abbas Araqchi, "[Senior European Union diplomat Helga] Schmid is supposed to call us this week and it's likely our experts will negotiate in the coming week in Geneva or Vienna to find a mechanism for implementation [of the agreement]," he said.
The agreement, seen as a first step to resolving a long-held tension between Iran and world powers on Tehran's nuclear program, was announced November 24th following talks in Geneva between the United States, France, Germany, China, Russia and Britain.
However, Araqchi emphasized to reporters that the deal was not legally binding and could be undone "The moment we feel that the opposite side is not meeting its obligations or its actions fall short. We are in no way optimistic about the other side - we are pessimistic - and we have told them that we cannot trust you."
Iran's UN nuclear watchdog envoy told reporters that the implementation phase is expected to commence in January, but Western representatives have said that sanctions relief would depend on UN inspectors' reports on whether or not Iran was upholding its end of the deal.
The historic deal aims to curb Iran's nuclear program development using sanction relief as a critical bargaining chip.
