Qatar’s Prime Minister Sheikh Mohammed bin Abdulrahman Al Thani arrived in Tehran on Thursday for talks aimed at reviving stalled US-Iran negotiations and addressing the worsening crisis in the Strait of Hormuz, where a tanker was struck by an unidentified projectile the same day.
The visit comes six months into the US-Iran war and weeks after the collapse of a June 17 memorandum of understanding that had briefly raised hopes for a diplomatic resolution. Qatar, which played a direct role in brokering that deal, is now attempting to bridge widening gaps between Washington and Tehran as shipping through the strait remains at a fraction of pre-war levels.
“The talks will cover regional security, the resumption of dialogue and freedom of navigation in the Strait of Hormuz and the need for it to return to the status quo prior to February 28,” Qatari Foreign Ministry spokesman Majed Al Ansari said ahead of the visit.
On the eve of Sheikh Mohammed’s arrival, Iran’s Islamic Revolutionary Guard Corps issued a stark statement declaring that the strait was under its control and that no vessel could cross it “without Iran’s permission and management.” The IRGC said it had been negotiating with Oman for about a month on “the share of each country in the strait and its revenues” and accused Washington of obstructing the process.
“If the United States stops obstructing and returns to the agreement, we can open the Strait of Hormuz within the framework of the agreement reached. Therefore, our conditions must be accepted by the United States.”
Oil flows through the strait have collapsed to roughly five million barrels per day, down from approximately 20 million before the war began on February 28, according to Reuters. The International Maritime Organization has confirmed 65 shipping incidents and 17 seafarer fatalities since the conflict started, making the waterway one of the world’s most dangerous maritime corridors for commercial vessels.
Tanker Attack Undermines Diplomatic Window
The tanker attack reported by UK Maritime Trade Operations on August 27, designated Warning 121-26, struck a vessel near Khasab, Oman, at the strategic entrance to the strait’s southern corridor. The fire was extinguished and all crew members were reported safe. No further details on the vessel’s identity or cargo were released as authorities investigated.
The incident followed the disabling of the Aframax tanker Metro Venetian by an unknown projectile on August 24, roughly nine nautical miles northeast of Ash Shishah, Oman. That vessel was struck while outbound with jet fuel, sustaining engine-room damage that temporarily disabled it before it proceeded to Fujairah under its own power. A chief engineer aboard the bulk carrier Minoan Dignity was killed in a separate attack around August 17 to 18.
Commercial shipping companies have been progressively abandoning the southern transit corridor through Hormuz, with the IMO recording a steady decline in independent vessel traffic. War-risk premiums have surged to 7.5 to 10 percent of hull value, compared with 1 to 3 percent before the conflict, adding enormous costs to every voyage through the area.
Diplomatic Momentum Falters
Trump told Al Jazeera on Wednesday that he had “no time schedule” for when he expects to resume negotiations with Iran, dampening expectations ahead of the Tehran talks. The comment came as the US shifted its approach from military strikes to economic pressure, with Secretary of State Marco Rubio telling allied foreign ministers on August 25 that no new American strikes on Iran are expected “for the time being.”
The US has been on a 27-night pause in strikes since August 1, when Trump canceled a threatened multi-day campaign. The focus has moved to a sweeping sanctions package announced on August 24, which named approximately 60 companies, individuals and vessels across the UAE, Hong Kong, China, Singapore, Switzerland and Europe, though it stopped short of targeting major Chinese banks. Israeli Prime Minister Benjamin Netanyahu congratulated Trump and Treasury Secretary Scott Bessent after the sanctions announcement.
Oil markets reflected the mixed signals. Brent crude fell $2.30 to $86.28 per barrel on August 26, its third consecutive daily decline, as the market priced in the probability of a diplomatic opening rather than an actual increase in supply. The benchmark compares with $66 immediately before the war and a March peak of $119. US retail gasoline national average stood at $4.10 per gallon, more than a dollar above year-earlier levels.
Regional Fallout Deepens
The UAE has suspended all financial and economic transactions with Iran, a significant escalation given Abu Dhabi’s historically important commercial relationship with Tehran. Washington has praised the move as part of its broader campaign to isolate Iran’s economy. Dubai International Airport handled 31.5 million passengers in the first half of 2026, down 31.3 percent year-on-year, with the Iran war identified as a major cause.
Iran and Oman are reportedly negotiating a temporary maritime arrangement that could establish rules for commercial shipping through Hormuz, with one proposal excluding military vessels from the corridor. The arrangement, if finalized, would represent the first practical step toward restoring some degree of normalcy to the waterway, though significant questions about enforcement and verification remain unresolved.
For Qatar, the Tehran visit represents an effort to preserve the ceasefire framework and prevent a complete breakdown in communication between the warring parties. Doha has served as a key back-channel throughout the conflict, hosting diplomatic contacts that neither side could conduct directly. The small Gulf state played a direct role in securing the June ceasefire and hosted the negotiations that produced the 14-point memorandum of understanding.
But the gap between diplomatic rhetoric and conditions on the water remains wide. The IRGC’s insistence on Iranian control over Hormuz, combined with continued attacks on commercial shipping, undermines the very negotiations Qatar is trying to advance. With oil flows at 25 percent of pre-war levels, the IEA recording Gulf production 8.3 million barrels per day below pre-war levels, and the US Energy Information Administration projecting no recovery to near-pre-conflict output until early 2027, the economic cost of the standoff continues to mount for Gulf states and global energy markets alike.
