The Strait of Hormuz remains open to all shipping except vessels linked to "Iran's enemies", Iran's representative to the UN maritime agency was quoted as saying in Iranian media reports published on Sunday.
The threat of Iranian attacks during the US-Israeli war on Iran has kept most ships from getting through the narrow strait, the conduit for around a fifth of global oil and liquefied natural gas supplies, threatening a global energy shock.
Ali Mousavi said Tehran was ready to cooperate with the International Maritime Organisation to improve maritime safety and protect seafarers in the Gulf, adding that ships not linked to "Iran's enemies" could pass the strait by coordinating security and safety arrangements with Tehran.
"Diplomacy remains Iran's priority. However, a complete cessation of aggression as well as mutual trust and confidence are more important," Mousavi said, adding that Israeli and US attacks against Iran were at the "root of the current situation in the Strait of Hormuz".
