Saudi Crown Prince Mohammed bin Salman and US President Donald Trump held a telephone conversation on Friday that focused on the trajectory of US-Iran negotiations and the protection of maritime traffic through the Strait of Hormuz. According to the Saudi Press Agency, the two leaders reviewed bilateral cooperation and regional developments, and they stressed the importance of safeguarding navigation, securing international sea lanes, and supporting all efforts that contribute to regional security and stability. The readout explicitly listed the ongoing talks between Washington and Tehran among the files discussed.

While the call was underway, Iranian Foreign Minister Abbas Araghchi departed for Oman at the head of a diplomatic delegation. Iranian state-linked media reported that the visit would address bilateral relations and regional developments, with particular attention to the situation in the Strait of Hormuz. Separately, an Iranian technical and legal delegation led by Deputy Foreign Minister Kazem Gharibabadi held trilateral meetings in Doha with Qatari and Pakistani mediators to advance implementation of the Islamabad agreement aimed at ending the war. US envoys Steve Witkoff and Jared Kushner were also present in the Qatari capital, where they met Emir Tamim bin Hamad Al Thani and Prime Minister Mohammed bin Abdulrahman Al Thani. US officials told reporters in Washington that the administration had given Tehran until Saturday to publicly condemn recent attacks on vessels in the Strait of Hormuz and to declare that all shipping routes through the waterway are open without the imposition of tolls.

The flurry of diplomatic activity unfolds against the backdrop of US-Iran negotiations that, according to Russian media reports, address Iran’s nuclear programme, the lifting of American sanctions, and the unfreezing of Iranian assets. The same reports note that Saudi Arabia has previously pursued reconciliation with Iran through Chinese, Omani and Iraqi mediation, a process that restored diplomatic relations after a years-long rupture. Viewed from Riyadh, the phone call with Washington reinforces a joint posture on maritime security at a moment when the Strait of Hormuz—a conduit for a significant share of global oil shipments—has become a focal point of military and diplomatic pressure.

Riyadh and Washington have signalled through parallel channels that they are coordinating closely. Saudi Foreign Minister Prince Faisal bin Farhan spoke by telephone with US Secretary of State Marco Rubio on the same day, with both sides underlining the importance of continued consultation to bolster regional security. The immediate next marker is the Saturday deadline communicated by US officials, while the Iranian diplomatic missions in Muscat and Doha indicate that Tehran is simultaneously engaging multiple regional interlocutors. The state of the dossier remains fluid, with the US-Iran track, the Saudi-Iranian détente, and the security of the Strait of Hormuz now intersecting in a concentrated diplomatic sequence.
