On April 13, significant differences emerged during the negotiations between the United States and Iran in Islamabad. According to BlockBeats, Nabavian, the Vice Chairman of the National Security Committee of Iran's Islamic Parliament, highlighted three major points of contention.

The U.S. proposed an equal share of profits and management in the Strait of Hormuz with Iran. Additionally, the U.S. demanded that Iran export all uranium enriched to 60% and relinquish all uranium enrichment rights for the next 20 years.

Nabavian emphasized that the Iranian delegation firmly defended the nation's interests and resisted these demands.
