US National Security Adviser Jake Sullivan announced that his country and Iran have made reasonable progress to reach "the point at which Iran and the United States can return to the nuclear agreement based on mutual compliance," and that there are still a number of unresolved issues.
Sullivan said, during a meeting with the Economic Club in Washington, that US President Joe Biden will sign a nuclear agreement with Iran if he believes that this agreement restores the Iranian nuclear program to the status it was in 2018, and that it protects American national security interests.
He pointed out that things will become clear in the coming days or weeks.
Iran has been engaged in negotiations with the West for a year;
In an effort to bring the United States back to the 2015 agreement on Tehran's nuclear program, the agreement would allow the lifting of sanctions imposed on Tehran, allowing it to access its frozen funds abroad.
The nuclear deal provided for sanctions relief for Iran in exchange for restrictions on its nuclear program to ensure that it could not develop nuclear weapons, something Tehran has always denied.
But the unilateral withdrawal of the United States from the agreement in 2018 under the presidency of Donald Trump and the re-imposition of tough economic sanctions on Iran, prompted Tehran to retreat from some of its commitments.
In a related context, the Director-General of the International Atomic Energy Agency, Rafael Grossi, said that Iran had informed the agency of the start of work to produce components for centrifuges at the Natanz facility in central Iran, which is the largest uranium enrichment plant in the country.
Grossi said in a report obtained by Al Jazeera that Iran requested on the ninth of this April to install surveillance cameras at the Natanz site, and that the agency completed the process of installing the cameras and removed the seals on April 12.
