U.S. Secretary of State Marco Rubio is embarking on a diplomatic tour of the Gulf, visiting the United Arab Emirates, Kuwait, and Bahrain from Tuesday through Thursday to discuss the ongoing Iran nuclear negotiations with key regional allies.

The trip aims to align Gulf partners with Washington’s strategy as the United States engages in active talks with Tehran.

A central point of contention among regional officials is the potential establishment of a $300 billion reconstruction fund for Iran.

Rubio’s itinerary comes shortly after he announced that Iran has agreed to discuss parts of its nuclear program that had previously been off the table, marking a significant shift in the diplomatic posture.

A central point of contention among regional officials is the potential establishment of a $300 billion reconstruction fund for Iran.

Gulf states have historically opposed any financial mechanisms that could bolster Tehran’s economy without stringent safeguards, viewing such funds as a risk to regional security and stability.

The diplomatic push follows recent meetings between Rubio and special envoy Steve Witkoff with Qatari mediators in Miami, highlighting the growing role of third-party facilitators in the process.
