Iran says Strait of Hormuz sovereignty is non-negotiable as Araghchi outlines a two-stage deal with the United States

On 12 June 2026, Iranian foreign minister Abbas Araghchi stood before reporters and declared the country's sovereignty over the Strait of Hormuz non-negotiable, sketching a two-stage arrangement with Washington that links any broader understanding to an immediate cessation of hostilities. The remarks, carried in real time across Iranian state media and conflict-monitoring channels, arrived against the backdrop of an acute naval blockade, active strikes on Lebanon, and a region watching to see whether diplomacy can take the temperature down before the next escalation writes itself.

What is on the table, on Araghchi's telling, is a sequenced deal: first, a permanent end to the war on all fronts, including Lebanon; then, a wider package in which the United States commits not to interfere in Iran's affairs and to lift sanctions on Iranian oil, petrochemical products and banking, with the Strait of Hormuz reopening as part of the settlement. Iranian state outlets and conflict monitors circulated these elements as the working architecture of a memorandum of understanding being negotiated, with Tehran framing the strait as the sovereign lever it intends to keep.

The two-stage architecture

The Iranian framing, as reported by Mehr News and relayed through Telegram channels tracking the negotiations, runs in clear tiers. Phase one is an immediate, complete and permanent cessation of the war across every front, paired with an end to what Tehran calls external interference and an arrangement on the strait that respects Iranian control. Phase two attaches the economic lift: sanctions on Iranian oil, petrochemical exports and access to the international banking system come off in response to verifiable Iranian steps on its nuclear programme, with the Strait of Hormuz reopening inside that same envelope. Tasnim reported late changes to the text in the final hours of negotiation, a tell that the sequencing was still being fought over, not signed.

The legal backdrop is older than the current crisis. Under the United Nations Convention on the Law of the Sea, the strait is an international waterway through which coastal states may not suspend transit passage; Iran's claim of sovereign control sits in tension with that framework even as Tehran wields the geography as leverage. Araghchi's language reframes that tension as a negotiating fact rather than a settled legal one.

What the Western read looks like so far

The Western-wire read of Araghchi's 12 June remarks was still emerging at the time of publication. The sequence of statements around the memorandum was being carried by Iranian state channels and conflict-monitoring accounts, with the diplomatic and legal implications being parsed in real time. That sourcing shape matters: it means the analysis below is built on Iranian framing of its own opening position, with Western commentary sparse and still forming.

French president Emmanuel Macron welcomed the emerging agreement as the product of a diplomatic effort to which several partners contributed and called for rapid and full implementation. A joint statement from France, Britain, Germany and Italy held out the prospect of sanctions relief in response to clear and verifiable Iranian nuclear steps, language that aligns with the E3's longstanding position. British prime minister Keir Starmer called the deal a major step towards ending the war, restoring regional stability and reopening the strait. Qatar's foreign ministry, writing from Doha, welcomed the memorandum as a way to address outstanding issues. Pakistan's prime minister Shahbaz Sharif, whose government hosted the Islamabad talks, claimed credit for brokering the arrangement. None of these endorsements resolves the underlying question of what Tehran is actually conceding.

The blockade, the strikes, and the gap between the lines

The deal text and the battlefield are not the same document. U.S. president Donald Trump, posting to Truth Social, declared the deal complete and announced an end to the naval blockade of Iranian ports; Iran's Supreme National Security Council said the memorandum text was finalised on the evening of the negotiations. Yet reporting carried across conflict channels on 14 June noted that Israel was continuing to strike Lebanon even as the U.S.-Iran track was being announced. Vice president JD Vance, in a Fox News interview, called the emerging deal a big moment for the United States and said it would reopen the strait and ensure Iran will never have a nuclear weapon.

That gap is the story. A sequenced deal that pairs a permanent end to the war with sanctions relief and a reopened strait assumes that the war can actually be paused on all fronts simultaneously, that the naval blockade can be dissolved without re-escalation, and that the Israeli campaign in Lebanon is inside the political envelope Washington just negotiated. Each of those is an open question. The Associated Press, in a piece relayed through Iranian state media, wrote that Iran had achieved a new lever in the strait, a read that treats the geography itself as the prize Tehran intends to hold.

What Araghchi is buying with the word "permanent"

The choice of the word "permanent" in the Iranian framing is not incidental. Mehr's summary of the memorandum lists, as the first clause, a permanent and immediate cessation of the war on all fronts, including Lebanon. That is a higher bar than a ceasefire: it asks for a structural change in the conflict's status, not a pause. The U.S. side, through Vance's comments, framed the deal in terms of outcomes (reopened strait, no Iranian nuclear weapon) without committing publicly to the permanence language. The text matters because permanence is what survives a change of administration, a change of government in Tehran, or a single serious provocation. It is also what is hardest to verify.

The E3 statement's reference to clear and verifiable steps reads in the opposite direction: a verification architecture that lets sanctions snap back if Iran moves. The two languages are not necessarily incompatible, but they are not the same language, and the distance between them is where the next round of negotiation will live.

Stakes and what to watch

Three things to watch in the days ahead. First, the signed text of the memorandum, which Iran's Supreme National Security Council said was finalised on the evening of the negotiations: the gap between the Iranian read of permanence and the Western read of verifiability will be visible in the clauses. Second, the status of Israeli operations in Lebanon, which were continuing as the U.S.-Iran track was being announced and which sit outside the bilateral envelope by design. Third, the Strait of Hormuz itself. Trump said the waterway would reopen on Friday once the agreement was signed; whether it does, and on whose terms, is the test of whether Tehran has converted its geographic position into durable leverage or a one-off concession that the next crisis will reopen.

The legal status of the strait under UNCLOS remains a separate, well-established question that this deal does not settle. What it settles, if it holds, is the immediate temperature. What it does not settle is the architecture underneath.
