Iran and Oman on Tuesday said they had agreed on a framework for a temporary navigation corridor through the Strait of Hormuz and a joint project to clear mines from the waterway.
The agreement was discussed by Iranian Foreign Minister Abbas Araghchi and his Omani counterpart Badr al-Busaidi during talks in Tehran, according to a joint statement issued by Oman.
The framework includes a phased plan for establishing a temporary navigational corridor and carrying out mine-clearing operations in the Strait. Technical negotiations will continue on creating a permanent corridor and determining future arrangements for administering the waterway, the statement said.
The talks will also address information-sharing, traffic management and navigational and security services. Iran and Oman said discussions should also involve other states bordering the Gulf.
The announcement came as US President Donald Trump claimed on Truth Social that all mines had been removed or detonated from international waters in the Strait of Hormuz. He warned that any vessel placing new mines would be “immediately and systematically destroyed”.
The war began on February 28 after the US and Israel attacked Iran. Tehran subsequently blockaded the Strait of Hormuz, while Washington imposed a naval counter-blockade on Iranian ports.
Traffic through the waterway remains largely paralysed, disrupting global oil markets. The Strait normally carries around one-fifth of the world's oil and liquefied natural gas exports.
Iran and Oman, which both border the Strait, have been discussing navigation arrangements for weeks. Tehran has said the geographical coordinates of a proposed route have been agreed.
Iranian officials have maintained that the strait will not fully reopen until the US lifts its naval blockade and oil sanctions and unfreezes Iranian assets abroad.
