Iran has said that "non-hostile vessels" may pass through the Strait of Hormuz provided they coordinate with "the competent Iranian authorities".
In a statement on Tuesday, Iran’s mission to the United Nations said vessels may avail of “safe passage” through the waterway, “provided that they neither participate in nor support acts of aggression against Iran and fully comply with the declared safety and security regulations.”
Iran earlier shared a similar statement about the status of the strait with the International Maritime Organization (IMO), the UN body responsible for the safety and security of international shipping.
Tehran did not elaborate in the statements on what regulations vessels need to follow to safely navigate the strait, through which about one-fifth of global supplies of oil and liquefied natural gas usually transit.
Iran’s remarks came as United States President Donald Trump said negotiations were under way to end the US-Israel war on Iran, despite Tehran’s previous denials that the sides were in talks.
While a small number of ships are passing through the strait each day, traffic remains at a fraction of the levels seen before the US and Israel launched their war on Iran on February 28.
Five vessels were tracked transiting the waterway via their automatic identification systems on Monday, down from an average of 120 daily transits before the conflict, according to maritime intelligence firm Windward.
While Iran warned in the initial days of the conflict that any ship attempting passage would face attack, officials in Tehran have in recent weeks insisted that the waterway remains open, except to “enemies”.
The collapse of shipping in the strait has prompted a surge in global energy prices, with some analysts predicting oil could rise to $150 or even $200 a barrel if the waterway stays effectively closed.
