Marco Rubio said a memorandum of understanding serves as a framework for negotiations rather than a comprehensive agreement [1].

This distinction is critical for diplomatic clarity, as it defines the boundaries of ongoing talks without committing the U.S. to a final, binding treaty. By framing the document as an outline, the administration maintains flexibility in its negotiating position while signaling intent to partners.

Rubio said that the memorandum is designed to set the broad lines for discussions [1]. This approach allows negotiators to address specific concerns and refine terms before moving toward a formal contract. He said that the document provides the necessary structure for dialogue without finalizing the terms of the deal [1].

Beyond the framework of negotiations, Rubio addressed specific security and financial constraints regarding regional stability. He said there will be no money for Iran and that the U.S. will not agree to any measure that threatens the security of the Gulf [2]. These statements reinforce a hardline stance on Iranian funding and regional deterrence.

Rubio also spoke on the status of critical maritime routes. He said the Strait of Hormuz is an international waterway and that no country has the right to impose transit fees upon it [3]. This position aligns with international maritime law and ensures the free flow of global commerce through the region.

Throughout his statements, Rubio said that the current diplomatic stage is about establishing parameters. By separating the memorandum of understanding from a final agreement, the U.S. avoids premature commitments while continuing to engage in high-level diplomacy [1].

The memorandum of understanding is not a comprehensive agreement, but rather sets the outlines for negotiations.

The distinction between a memorandum of understanding and a final agreement allows the U.S. to signal diplomatic openness while avoiding legal obligations. By explicitly rejecting Iranian funding and transit fees in the Strait of Hormuz, the administration is balancing these preliminary talks with a commitment to regional security and international maritime law.
