A move seen as a key step towards lifting UN, EU and US sanctions, and accordingly, world companies will be at more ease to do business with Iran.
UN watchdog closes Iran nuclear weapons inquiry and backs Tehran deal. In a symbolic victory for Iran, International Atomic Energy Agency passes a resolution ending long-running investigation
The U.N. nuclear watchdog's 35-nation board decided on Tuesday 15 December 2015, to close its investigation into whether Iran once had a nuclear weapons programme, opting to support Tehran's deal with major powers rather than dwell on its past activities.
According to this watchdog, the IAEA, ended its 12-year investigation into concerns that Iran might be developing nuclear weapons.
The United States, Russia, Britain, France, Germany and China reached a deal with Tehran in July under which sanctions weighing on Iran's economy will be lifted in exchange for restrictions on the Islamic Republic's atomic activities.
With companies from the six powers and other nations lining up to do business in the Islamic Republic once sanctions are lifted, there had been little opposition to the resolution.
The move is seen as a key step towards lifting UN, EU and US sanctions, and accordingly, world companies will be at more ease to do business with Iran.
The BBC's Bethany Bell in Vienna says sanctions against Iran could be lifted as early as the middle of January.
