Overview

U.S. Secretary of State Marco Rubio is scheduled to travel from Tuesday, 23 June 2026, through Thursday, 25 June 2026, to the United Arab Emirates, Kuwait and Bahrain. The purpose of the trip, as stated by State Department spokesperson Tommy Pigott, is to discuss the Trump administration’s preliminary Iran memorandum of understanding (MoU) with Gulf Arab allies.

Meetings and Agenda

During the visit, Rubio will meet the Gulf Cooperation Council (GCC) in Bahrain. The GCC comprises six Sunni states: Saudi Arabia, Qatar, Oman, the United Arab Emirates, Kuwait and Bahrain. According to Pigott, Rubio will discuss a range of regional priorities, including the MoU with Iran, efforts to secure full and free safe transit through the Strait of Hormuz, and the broader importance of peace and stability in the region.

Gulf Concerns Over the Iran MoU

Gulf leaders have broadly supported initiatives aimed at ending the U.S.–Israeli conflict with Iran, but they have expressed specific concerns about two key provisions of the MoU:

  • Reconstruction Fund: The memorandum includes a $300 billion reconstruction fund for Tehran. Gulf officials fear that Iran could divert these resources to rebuild its military capabilities and fund regional proxy groups.
  • Ballistic Missile Program: The MoU does not address Iran’s ballistic missile program, a point of anxiety for Washington’s Gulf allies who have recently experienced Iranian missile and drone attacks.

Context of the MoU

President Donald Trump signed the Iran MoU on Wednesday, 22 June 2026, while visiting French President Emmanuel Macron in Versailles. The agreement initiates a 60‑day period for Washington and Tehran to negotiate a more comprehensive deal.

Parallel Negotiations

A team of U.S. negotiators, led by Vice President JD Vance, participated in talks mediated by Qatari and Pakistani officials in Switzerland over the weekend. The first round of those talks concluded on Monday, 22 June 2026, and technical discussions are expected to continue throughout the week.

Strategic Implications

The UAE, Saudi Arabia, Kuwait, Bahrain and Qatar host U.S. military bases that constitute the backbone of America’s security architecture in the Middle East. Rubio’s visit therefore seeks to reassure Gulf partners while addressing their concerns about the potential military and proxy‑warfare implications of the Iranian reconstruction fund and the omission of missile‑program restrictions.
