But disagreements remain regarding shipping routes via the crucial Strait, through which around a fifth of global oil production typically flows.
The traditional route, used before the Iran war, takes vessels on a central voyage down the Strait. However, there are concerns about mines and other high-risk factors. Despite some progress, two merchant vessels were struck last week.
Washington has promoted a southern lane along the coast of Oman, which could enable evasion from Iranian officials.
Last week, Oman announced a temporary maritime corridor in coordination with the International Maritime Organization as commercial traffic gradually resumed after weeks of disruption.
The Islamic Revolutionary Guard Corps (IRGC) had warned ships to coordinate with its navy and use designated Iranian-controlled routes.
Iran’s Foreign Minister Abbas Araghchi is adamant “any interference or attempt to create parallel arrangements will only complicate the situation, increase tensions and delay the reopening of this vital waterway.”
