Rubio ’ s Gulf tour is the first high-level diplomatic mission since the US-Iran framework agreement last week. United States Secretary of State Marco Rubio has warned that any Iranian tolls on ships traversing the Strait of Hormuz would spread to other waterways “ like a contagion ”, as he wrapped up a trip to the Gulf aimed at winning support from regional allies for the US-Iran interim deal aimed at ending their war. Observers say this could mark a turning point in how the issue is addressed.

Background

What is happening now can be traced back to a series of decisions and events that preceded it.

“ International waterways do not belong to any nation state, ” Rubio stated on Thursday following joining a Gulf Cooperation Council meeting in Bahrain.

“ If in fact we accepted that you can charge money to use an international waterway because it happens to be near your territorial space, well then this will spread throughout the world like a contagion, ” he emphasized.

Compounding the significance of these events, he said that there was zero support among Gulf countries for any Iranian toll on ships transiting the Strait of Hormuz.

Rubio earlier told partners in the Gulf that any deal to end the US-Iran war would account for their security interests.

International Reaction

Those with expertise in the area say the timing of this development is particularly notable.

Rubio ’ s three-day tour of the Gulf is the first high-level diplomatic mission since the US and Iran agreed a Memorandum of Understanding to extend their ceasefire and to hold talks on a permanent end to the more than 100-day war, which started on February 28 with US-Israeli strikes on Iran.

Reports further indicate that he acknowledged the delicacy of his mission as he seeks to win over Gulf Arab leaders wary that excessive concessions could strengthen Tehran and reshape the region ’ s security balance and oil flows.

Reports further indicate that in Manama, he told leaders from Bahrain that the US wants to ensure any agreement with Iran takes into account the “ interest of allies ”.

In what observers are describing as a key detail, he added: “ We are open for peace that is enduring and real and doesn ’ t undermine security and prosperity for the US or its allies ”.

What It Means

The story's impact will be felt at multiple levels — local, national, and beyond.

Rubio said throughout a developments conference in Manama that a reconstruction fund for Iran was not discussed with Gulf countries.

In what observers are describing as a key detail, he said he would not be asking regional allies to contribute to any reconstruction fund amid the trip, even as the MoU with Iran suggests that countries in the region would at least be partially responsible for footing the bill.

According to those with knowledge of the situation, at his previous stops in the United Arab Emirates ‌and Kuwait, Rubio sought to assure officials that the proposed deal ‌was not overly favourable to Iran, which attacked several Gulf states during the war.

In what observers are describing as a key detail, “ We ’ re not going to do anything that undermines the security of our allies, our longstanding allies in the region, ” he notified reporters in Kuwait.

Next Steps

A clearer picture is expected to emerge as more information comes to light in the days ahead. Until then, this development remains a pivotal point in an ongoing story with significant national implications.
