IAEA Director General Emphasizes Need for Verification in US-Iran Talks

Seoul: On Wednesday, the leader of the UN's nuclear oversight body highlighted the necessity for comprehensive verification measures regarding Iran's nuclear activities as part of any potential agreement between the US and Iran aimed at resolving their ongoing conflict in the Middle East.

Rafael Grossi, the Director General of the International Atomic Energy Agency (IAEA), underscored the importance of a robust verification framework for Iran's nuclear program. This statement came as US President Donald Trump indicated that a second round of discussions with Iran could take place within the next couple of days.

The Trump administration has consistently stated that a primary objective of the conflict is to prevent Iran from acquiring nuclear weapons. While Iran maintains that it is not pursuing such weapons, it has also dismissed any restrictions on its nuclear program.

Recently, initial discussions held in Pakistan between the two nations did not yield a consensus. The White House identified Iran's nuclear aspirations as a significant hurdle. However, an Iranian diplomatic source, who requested anonymity due to the sensitive nature of the negotiations, refuted claims that talks had collapsed over this issue.

Grossi remarked that Iran's extensive nuclear program necessitates the presence of IAEA inspectors to ensure any agreement is genuine rather than merely an illusion.

He emphasized that any accord concerning nuclear technology must incorporate meticulous verification protocols.

According to a confidential IAEA report shared with member states and reviewed by the Associated Press in February, Iran has not permitted IAEA access to its nuclear sites that were targeted by Israel and the US during a 12-day conflict in June.

The report indicated that the IAEA cannot confirm whether Iran has halted all enrichment activities or ascertain the quantity of uranium stored at the impacted facilities.

Iran has long asserted that its nuclear program is for peaceful purposes; however, the IAEA and Western nations contend that Tehran had a structured nuclear weapons initiative until 2003.

The IAEA has reported that Iran possesses a stockpile of 440.9 kilograms of uranium enriched to 60% purity, which is a short technical step from achieving weapons-grade levels of 90%.

This stockpile could potentially enable Iran to manufacture up to 10 nuclear bombs if it chooses to weaponize its program, Grossi stated earlier.

Typically, such highly enriched nuclear material should be verified monthly, as per IAEA guidelines.

During the press conference on Wednesday, Grossi also noted a significant uptick in activities at North Korea's nuclear facilities. His remarks align with observations from various foreign analysts who believe North Korea has been expanding its primary Yongbyon nuclear complex and establishing additional uranium enrichment sites since its diplomatic efforts with the US faltered in 2019.

In September, South Korea's Unification Minister Chung Dong-young reported that North Korea was operating four uranium enrichment facilities, all of which were reportedly active daily.
