Iran's top negotiator, Mohammad-Bagher Ghalibaf, said on Friday in a post on X/Twitter that Tehran does not trust guarantees or words and would judge by actions, adding that Iran would not act unless the other side acted first.
"We seize concessions not through dialogue, but with missiles," said Ghalibaf. "In negotiations, we merely make them understand."
"The winner of any agreement is the one who is better prepared for war from the day after," he added.
Earlier on Friday, Iranian Foreign Minister Abbas Araghchi said he had discussed the Strait of Hormuz and its future administration with Omani Foreign Minister Badr Albusaidi in line with their sovereign responsibilities and international law.
In a post on X, Araghchi said he also expressed Iran's solidarity with Oman against any threat.
"We welcome consultation with all neighboring states, added Araghchi.
US-Iran deal not yet finalized
The United States and Iran reached an agreement on Thursday to extend their ceasefire and lift restrictions on shipping through the Strait of Hormuz, sources told Reuters, though US President Donald Trump has yet to approve it, and Iranian state media said it had not been finalized.
According to an Axios report citing two US officials, the proposed memorandum of understanding would last 60 days and begin negotiations toward a final agreement on Iran’s nuclear program.
The semi-official Iranian state media outlet Tasnim denied on Thursday that the draft memorandum of understanding had been finalized.
