Nuclear negotiator and Deputy Foreign Minister Seyed Abbas Araghchi said that the date of the final implementation of the nuclear deal will be announced by Jan. 17, paving the way for the end of international sanctions.

Araghchi said that the International Atomic Energy Agency would issue a report Jan. 15 clearing Iran’s past nuclear activities. He added that Foreign Minister Mohammad Javad Zarif and European Union foreign policy chief Federica Mogherini would announce the day of the implementation of the nuclear deal in a joint statement.

Iran and the five permanent members of the UN Security Council plus Germany reached a landmark nuclear deal in July that required Iran to reduce the size of its nuclear program for the first time in over a decade in exchange for sanctions relief from the United States, the European Union and the UN Security Council.

Araghchi said that since the deal was made, “many difficult tasks have been completed” in order to reach the final implementation phase. He reiterated that Iran’s Supreme National Security Council and Supreme Leader Ayatollah Ali Khamenei both signed off on the nuclear deal.
