Writing in Foreign Affairs, Zarif said Iran should offer to limit its nuclear program and reopen the Strait of Hormuz in exchange for a comprehensive lifting of U.S. sanctions, a proposal he said Washington had previously rejected but might now consider under changed circumstances.

The remarks come as the United States has put forward a 15-point ceasefire framework that includes restoring maritime access through the Strait of Hormuz, though there has been no indication of progress in negotiations.

Zarif, who played a central role in negotiating the 2015 nuclear agreement, no longer holds an official government position but remains an influential figure. Analysts note that such proposals are unlikely to be published without at least informal alignment with senior leadership in Tehran.

Iranian officials have repeatedly pointed to past instances in which negotiations with Washington coincided with military action, including the current conflict, as a source of distrust.

Zarif also criticized previous U.S. negotiating representatives, including Jared Kushner, questioning their expertise in geopolitics and nuclear policy.

The proposal underscores tentative signals of diplomatic maneuvering amid ongoing hostilities, even as military exchanges and tensions in the region continue.

In an interview published Monday, Trump said the United States was in talks with Qalibaf, a former Revolutionary Guard commander. Qalibaf denied the assertion in a statement, saying Washington was “promoting desires as news while threatening our nation at the same time.

Iran’s Foreign Ministry also dismissed the claim. Spokesperson Esmail Baghaei said no negotiations had taken place, though he confirmed that intermediaries had conveyed proposals to Tehran.

Baghaei said Iran would not overlook what he described as past breaches of diplomacy, referring to indirect talks in 2025 and early 2026 that were followed by military action involving the United States and Israel.

War pressure shapes diplomacy claimsThe exchange comes as Trump has increased pressure on Tehran to reach an agreement to end the ongoing conflict, now in its fifth week following joint U.S.-Israeli strikes launched in late February.

Trump warned that failure to reach a deal “shortly” could result in widespread destruction of Iran’s energy infrastructure and critical facilities, including desalination plants.

Qalibaf’s role under scrutinyQalibaf, long viewed as a pragmatic conservative within Iran’s political system, has previously been mentioned as a potential interlocutor for Western governments.

However, questions remain about his authority within Iran’s complex power structure following the death of Supreme Leader Ali Khamenei in a February airstrike.His successor, Mojtaba Khamenei, is believed to maintain ties with Qalibaf, though competing centers of power within Iran’s leadership continue to shape decision-making.

Analysts say references to Qalibaf as a negotiating channel may reflect both external pressure tactics and internal political maneuvering, as Tehran navigates wartime conditions and diplomatic isolation.
