Iran said on Monday that it was working with Oman to finalise a joint statement on a plan for ships to transit the Strait of Hormuz, a waterway that remains at the centre of US-Iran negotiations.

AP reported that Tehran said it had reached agreement in principle with Muscat on a transit plan and was still finalising the details. It remained unclear whether any arrangement would meet the United States' demand for a full commercial reopening of the waterway.

A deadline passes without a wider deal

The announcement came as a 60-day deadline in the US-Iran process expired. AP reported no public indication that the parties had settled a wider package, including detailed nuclear questions.

The announcement is a diplomatic development, not confirmation that commercial shipping has fully reopened.

What will show whether anything has changed

The immediate test is operational rather than rhetorical: published terms, responses from Oman and the United States, and the movement of commercial ships will show whether the statement changes conditions on the water.
