Iran has made clear that a deal with Oman on a new shipping arrangement for the Strait of Hormuz will not, by itself, reopen the strategic waterway. Tehran says the strait will reopen only after the United States accepts a broader set of Iranian conditions, while Washington has indicated that it is prepared to lift its blockade of Iranian ports once commercial shipping resumes without impediments.

US officials say they would not accept any arrangement on the waterway that would leave Iran in control.

The countries are finalizing an agreed route for shipping in case the strait reopens.
