US Secretary of State Marco Rubio met UAE President Sheikh Mohamed bin Zayed Al Nahyan and senior Emirati officials in Abu Dhabi on Wednesday, 25 June 2025, reaffirming Washington's security commitment to the Emirates and advancing diplomatic efforts around President Donald Trump's memorandum of understanding with Iran. The meeting formed a central stop in Rubio's June 23–25 Gulf tour spanning the United Arab Emirates, Kuwait, and Bahrain.

Key Developments

Rubio and Sheikh Mohamed discussed the Trump administration's recently announced memorandum of understanding with Iran, efforts to secure unimpeded maritime transit through the Strait of Hormuz, and the broader imperative of regional peace and stability. The State Department confirmed the two leaders also reviewed the strategic dimensions of the US–UAE bilateral relationship, covering defence and commercial cooperation.

State Department spokesperson Tommy Pigott said in a statement that the two sides discussed 'the strong bilateral U.S.–UAE ties and continued partnership in the areas of defense and commerce.'

What the US Said About Iran's Attacks

Washington offered pointed praise for Abu Dhabi's conduct during the recent regional crisis triggered by Iranian actions. According to Pigott, 'The Secretary thanked the UAE for their leadership and unparalleled support, praised their courage and resilience in the face of Iran's attacks, and reaffirmed the U.S. commitment to the security of the Emirates.'

The explicit reference to Iran's attacks — and the language of 'courage and resilience' — signals that Washington views the UAE as having borne direct pressure during the latest escalation, and is now publicly underscoring its security guarantees to Abu Dhabi.

Strait of Hormuz at the Centre of Talks

A recurring theme across Rubio's Gulf itinerary is the Strait of Hormuz, through which an estimated 20% of the world's traded oil passes. Ensuring 'full and free safe transit' through the waterway was listed as a core agenda item by the State Department ahead of the trip. Any disruption to Hormuz shipping — a scenario Iran has periodically threatened — would have immediate consequences for global energy markets and supply chains.

This comes amid heightened sensitivity around the strait following the recent Iran-related regional crisis, making Rubio's reassurances to Gulf partners particularly consequential.

Gulf Cooperation Council Context

The Gulf Cooperation Council (GCC) — comprising Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the UAE — remains a cornerstone of US strategic engagement in the Middle East. Rubio's three-nation tour is widely seen as a coordinated effort to shore up GCC confidence in Washington's regional posture at a moment when the Trump administration is simultaneously pursuing a diplomatic track with Tehran.

The dual-track approach — engaging Iran through a memorandum of understanding while publicly backing Gulf allies who have faced Iranian pressure — reflects the tightrope Washington is walking as it attempts to reshape the region's security architecture.

What Comes Next

Rubio's Gulf tour concludes on 25 June, after which the State Department is expected to provide a fuller readout of outcomes from all three stops. The durability of the Trump–Iran memorandum of understanding — and whether it translates into a verifiable reduction in Iranian regional activity — will determine how much reassurance Washington's Gulf partners ultimately derive from this round of diplomacy.
