French President Emmanuel Macron pledged on Monday to take all necessary measures to prevent Iran from imposing tolls on the Strait of Hormuz, a vital maritime passage for global oil shipments. This commitment came shortly after the United States and Iran reached a new agreement aimed at reducing tensions in the region.

Macron outlined plans for a joint mission with the United Kingdom to monitor and maintain free navigation through the Strait, one of the world’s most strategically important shipping lanes. The French Navy’s flagship aircraft carrier, Charles de Gaulle, is prepared to be deployed to the area within two to three days if needed, demonstrating France’s readiness to act swiftly to secure unimpeded access.

The announcement preceded the G7 summit hosted in France, where Macron emphasized the importance of open dialogue and cooperation among global powers to ensure stability in the Gulf. He also noted the intention to engage in a “respectful but firm” conversation with U.S. President Donald Trump after the latter threatened to impose a 100% tariff on French wine, highlighting ongoing tensions between the two allies even as they address broader international security concerns.

The new U.S.-Iran agreement, which aims to ease longstanding hostilities, was welcomed by international leaders as a positive step toward reducing the risk of conflict in a region that supplies a significant portion of the world’s oil. However, the potential for Iran to charge fees for passage through the Strait had raised concerns among trading nations, prompting Macron’s firm stance against any such measures.

Macron’s declaration signals a continued commitment by France and its allies to uphold the principle of free navigation at a time when geopolitical tensions threaten to disrupt critical global trade routes. The planned Franco-British mission and the rapid deployment capacity of the Charles de Gaulle underscore the strategic priority placed on preserving maritime security in the Gulf of Hormuz.
