Qatar's Prime Minister and Foreign Minister announced Monday that a memorandum of understanding between the U.S. and Iran has ended the war [1].

The agreement represents a significant shift in regional stability, aiming to lower tensions and reopen diplomatic channels after years of conflict.

Sheikh Mohammed bin Abdulrahman Al Thani made the announcement June 22, 2026 [1], during meetings in Doha with the foreign ministers of Iran and Saudi Arabia. He said the memorandum of understanding between Washington and Tehran is intended to stop the war and establish a basis for negotiations [1].

According to the prime minister, the cessation of hostilities was achieved through this diplomatic instrument. "We have reached the end of the war thanks to the memorandum of understanding between the United States and Iran," he said [2].

Qatar continues to act as a primary mediator in the region to facilitate communication between the opposing powers. Sheikh Mohammed bin Abdulrahman Al Thani said that Qatar is working to coordinate diplomatic efforts to reduce escalation, and restore negotiations between the two parties [3].

The diplomatic push in Doha seeks to replace military confrontation with a structured dialogue. By securing a memorandum of understanding, the U.S. and Iran have created a temporary framework that allows for the transition from active conflict to formal diplomatic engagement.

The goal of the memorandum of understanding between Washington and Tehran is to stop the war and establish negotiations.

This development indicates a strategic pivot toward de-escalation in the Middle East. By utilizing Qatar as a neutral intermediary, the U.S. and Iran have avoided a direct diplomatic encounter while establishing a ceasefire. The success of this memorandum will likely depend on whether the 'foundation for negotiations' leads to a comprehensive long-term treaty or remains a fragile truce.
