Iran's negotiations with Oman to determine a temporary route through the Strait of Hormuz was now in the "final stages",
Foreign Minister Seyed Abbas Araghchi said on Sunday.
Araghchi, through a Telegram messenger post on Sunday, said old shipping routes in the strait would be replaced with new ones in consultation with experts.
He also cautioned that the country was not reopening the strategically crucial waterway yet, with more conditions yet to be fulfilled.
This would include US compensation for Tehran for violations of a memorandum of understanding signed by the two countries in early June, he said in a separate Telegram post on Saturday.
He said the strait's ongoing closure was primarily the result of Washington's violation of that MoU.
