Iran informed the IAEA of its intention to stop voluntary implementation of the Additional Protocol of the Nuclear Non-Proliferation Treaty, in accordance with a December 2020 Iranian law. Iran’s IAEA envoy maintained that “as of 23 February, cooperation between Iran and the IAEA would be based solely on the country’s Safeguards Agreement with the Agency. If U.S. sanctions are effectively lifted”, he noted, “Iran would resume implementation of all voluntary measures”.
