Iran's Supreme Leader Ayatollah Mojtaba Khamenei said Thursday that he approved a memorandum of understanding with the U.S. [1].

This approval marks a significant shift in Tehran's diplomatic stance, as the leader said he initially held a different view regarding the framework. The deal potentially eases long-standing tensions between the two nations through a series of strategic concessions.

Khamenei said he gave his consent after receiving assurances that Iran's rights and interests would be protected [1]. He said the decision followed the U.S. decision to lift a blockade on Iranian ports [3].

"I have approved the memorandum of understanding after receiving assurances that Iran's rights will be respected," Khamenei said [1].

The Supreme Leader said the U.S. approach to the negotiations was a result of urgency. He said, "Trump used all kinds of levers to secure the deal out of desperation" [2].

Despite the approval, the transition to a formal agreement remains in flux. Reports indicate a potential signing ceremony could be scheduled for June 19, 2026 [6], though it remains unclear if the two sides will hold the event in Switzerland [6]. Other reports suggest that while the deal is approved, the focus has shifted toward the steps required for implementation [1, 2, 4, 5].

Khamenei said his approval came despite his original reservations. "I approved the US framework deal despite having a different view," he said [4].

"I have approved the memorandum of understanding after receiving assurances that Iran's rights will be respected."

The approval of this framework deal suggests a pragmatic pivot by the Iranian leadership, balancing internal ideological opposition with the economic necessity of lifting port blockades. By framing the U.S. concessions as a result of 'desperation,' Khamenei maintains a position of strength domestically while opening a diplomatic channel that could fundamentally alter sanctions regimes and maritime security in the region.
