US Secretary of State Marco Rubio on Thursday, 25 June reaffirmed Washington's security commitment to Bahrain during talks with King Hamad bin Isa Al Khalifa in Manama, as both sides pledged deeper cooperation on regional stability, freedom of navigation through the Strait of Hormuz, and preventing Iran from acquiring nuclear weapons.

Key Commitments Reaffirmed

At the heart of the bilateral meeting was a reaffirmation of the Comprehensive Security Integration and Prosperity Agreement (C-SIPA), the framework that underpins US-Bahrain strategic cooperation. According to a State Department readout, Rubio explicitly restated Washington's commitment to Bahrain's security under the agreement.

The two sides also aligned on a shared vision for Gulf stability, safe maritime transit, and ensuring Iran does not cross the nuclear threshold — positions that carry heightened significance following a 17 June memorandum of understanding between Washington and Tehran.

Rubio Condemns Iran's Attacks on Bahrain

In a pointed signal, Rubio condemned what the State Department described as Iran's recent attacks against Bahrain. 'The Secretary condemned Iran's attacks on Bahrain and reaffirmed unwavering U.S. partnership and solidarity with the Bahraini people,' the State Department said in its readout.

The condemnation came hours after Rubio co-chaired a ministerial meeting between the United States and the Gulf Cooperation Council (GCC), where regional leaders discussed the implementation of the June 17 US-Iran memorandum and broader Gulf security concerns.

Hard Line on Strait of Hormuz

Rubio drew a firm line on the question of tolls or charges on international shipping through the Strait of Hormuz. Speaking to reporters after the GCC ministerial, he said: 'If you are charging money to use the straits, we won't support it. We won't tolerate it; we won't allow it.' He described this as a position of unanimous agreement among Gulf partners.

Rubio also pledged that Washington would keep Gulf allies fully briefed throughout any ongoing negotiations with Iran. 'We're not going to do anything or agree to anything that they're not aware of, that our partners in the area are not aware of, that our partners in the area are not aligned with, and that in any way could undermine their security and their stability,' he said.

Economic Cooperation on the Agenda

Beyond security, Rubio and King Hamad explored avenues to broaden bilateral economic ties. The State Department readout cited discussions on deepening cooperation in energy, artificial intelligence, critical minerals, and other strategic sectors — signalling that the US-Bahrain relationship is being repositioned as a comprehensive strategic partnership, not merely a defence arrangement.

Why This Visit Matters

The Manama meetings underscore Bahrain's role as one of Washington's closest Gulf security partners at a particularly sensitive moment. Regional diplomacy has intensified since the US-Iran memorandum of understanding, and Gulf states have sought assurances that any Washington-Tehran deal will not compromise their security interests. Rubio's visit, and his pointed public statements on Iran and the Strait of Hormuz, appear designed to provide exactly that reassurance.

With GCC-US coordination now formally elevated and economic tracks opened alongside the security dialogue, the next phase will test whether diplomatic momentum translates into concrete agreements on the Iran nuclear file.
