Tehran blocks French role in Hormuz clearance

Iran has rejected French involvement in clearing mines from the Strait of Hormuz, declaring that Tehran alone will manage security operations in the strategic waterway under its memorandum of understanding with the United States.

The rejection, delivered by Deputy Foreign Minister Kazem Gharibabadi, followed President Emmanuel Macron’s offer for France to work with Oman and other partners on demining and safe passage through one of the world’s most important energy corridors. Tehran warned Paris against what it called “provocations” and said any mine-clearance work would be carried out only by Iran.

The dispute has sharpened a central weakness in the fragile US-Iran ceasefire: both sides say they support reopening the strait, but they disagree over who controls navigation, how vessels should move through the channel and whether outside powers can take part in securing shipping lanes. The Strait of Hormuz links the Gulf with the Arabian Sea and carries roughly a fifth of global oil consumption, making any disruption a direct risk to energy markets, insurance costs and Gulf export flows.

Gharibabadi’s statement framed demining as a matter of sovereignty rather than technical maritime safety. Tehran’s position is that Article 5 of the US-Iran memorandum gives Iran the lead role in managing the waterway. Washington and several Gulf partners view the strait as an international passage where safe navigation cannot be subject to unilateral control by either littoral state.

The disagreement comes after a series of maritime incidents that raised concern among tanker operators and naval commands. A commercial vessel trying to transit the strait was struck by a projectile last week, prompting US strikes against targets in southern Iran. Tehran did not formally claim responsibility for the vessel incident but has repeatedly warned ships against using routes it considers unsafe or politically unacceptable.

France’s proposal was designed to support a broader diplomatic push to reopen the channel through coordination with Oman, whose coastline forms the southern side of the strait. Oman has sought to position itself as a neutral manager of maritime arrangements, favouring a route that reduces the risk of confrontation while preserving international freedom of navigation. Tehran, however, has objected to any plan that shifts traffic towards the Omani side without its approval.

The latest exchange also exposes a widening contest among Iran, Oman, the US and European powers over the practical meaning of the ceasefire. For Tehran, control over passage through Hormuz remains a bargaining tool after months of conflict with Washington. For the US and its allies, the continued threat to commercial shipping undermines the purpose of the memorandum and keeps pressure on oil markets.

Energy traders have watched the dispute closely because even limited disruptions can raise freight rates and delay cargoes from Saudi Arabia, the UAE, Kuwait, Iraq and Qatar. While some Gulf producers have pipelines that bypass Hormuz, most export capacity still depends heavily on the waterway. LNG shipments from Qatar are especially exposed because alternative routes are limited.

Macron’s intervention placed France more openly in the maritime security debate. Paris has maintained a naval presence in the region and has previously coordinated with European partners on Gulf shipping protection. Its willingness to cooperate with Oman reflects concern that the ceasefire could break down if demining and passage rules are left unresolved.

Tehran’s response was uncompromising. Gharibabadi said the situation was “sensitive and complex” and warned that France should not make it more complicated. The wording suggested Iran sees the French move not as technical assistance but as an attempt to dilute its authority under the memorandum.

The US position remains tied to the principle that commercial traffic should move without coercion. Washington has backed efforts to establish safer transit corridors and has warned Iran against attacks on ships or interference with passage. At the same time, US envoys have continued diplomatic contacts through regional mediators to preserve the ceasefire and prevent a return to open conflict.

Qatar and Pakistan have played roles in keeping channels open between Washington and Tehran. Doha has hosted talks, while Islamabad’s earlier mediation helped shape the memorandum that halted the broader confrontation. But the Hormuz dispute shows that the agreement left key operational questions unresolved, particularly over maritime enforcement, mine clearance and the role of third countries.
