In a post on X, Qalibaf accused Donald Trump of attempting to turn diplomacy into a “table of surrender,” adding that Tehran was instead preparing “to reveal new cards on the battlefield.”His remarks come as a two-week ceasefire in a conflict that has killed thousands and disrupted global markets, particularly energy supplies, is set to lapse later this week.

The truce has come under strain following a U.S. move to seize an Iranian cargo vessel accused of violating a maritime blockade, prompting Tehran to warn of retaliation.

Iran has consistently rejected negotiations conducted under coercion, while Washington has maintained pressure through military and economic measures as part of its broader strategy toward Tehran.

The announcement came a day after talks in Pakistan ended without agreement, underscoring persistent divisions over terms to end a conflict launched on Feb. 28 by the United States and Israel. The blockade is aimed at pressuring Iran to reopen the Strait of Hormuz and accept a broader settlement addressing its nuclear and missile programs, as well as its regional activities.

Trump indicated that diplomatic channels remain open, saying Iran had reached out to explore a possible resolution. “We’ve been called by the right people … and they want to work a deal,” he told reporters outside the White House.Iran signaled conditional openness to negotiations.

Judiciary chief Gholam Hossein Mohseni Ejei said discussions must proceed on the basis of “principles and logic,” while other officials warned that Tehran would respond if the situation escalates.The blockade drew sharp reactions from Iran, which threatened countermeasures targeting ports across the Arabian Gulf and Gulf of Oman, raising the risk that the two-week ceasefire declared earlier could collapse before its April 22 expiry.

At the core of the dispute remain differences over Iran’s nuclear program and control of the Strait of Hormuz, a critical global energy corridor through which roughly one-fifth of the world’s oil supply typically passes. Its closure has already disrupted markets and driven up oil prices.

U.S. Vice President JD Vance, who led the American delegation in the recent talks, said Iran had not provided assurances it would refrain from pursuing nuclear weapons capability. Tehran has long denied such intentions while defending its right to civilian nuclear development, including uranium enrichment.

Iran’s negotiating position, articulated by Parliament Speaker Mohammad Bagher Qalibaf, emphasized sovereignty over the strait, an end to hostilities, and compensation for wartime damage.

Iranian officials also dismissed the blockade as exaggerated, with parliamentary spokesperson Ebrahim Rezaei describing it as “more bluffing than reality.”Pakistan has indicated it may facilitate further dialogue, with Foreign Minister Ishaq Dar expressing willingness to host another round of talks, though no timeline has been confirmed.

Both sides have maintained firm public positions, with Trump warning that any Iranian attempt to challenge the blockade would be met with force, while Iranian foreign ministry spokesperson Esmaeil Baqaei said the measure risked further destabilizing the global economy.

The discussions, held days after a Pakistan-brokered ceasefire, marked the first direct engagement between senior U.S. and Iranian officials since Iran’s 1979 Islamic Revolution. Delegations led by U.S. Vice President JD Vance and Iranian Parliament Speaker Mohammad Bagher Qalibaf met over more than 20 hours at Islamabad’s Serena Hotel, with Pakistani mediators shuttling between the sides.

Despite moments when negotiators appeared close to a framework agreement, talks ultimately stalled over key issues including Iran’s nuclear program, control of the Strait of Hormuz, and access to frozen assets, according to 11 sources familiar with the discussions.

A U.S. official said Washington’s core objective remained ensuring Iran does not obtain a nuclear weapon, while Iranian officials emphasized sovereignty concerns, sanctions relief, and broader security guarantees.

Iran has consistently denied seeking nuclear weapons but maintains its right to uranium enrichment.Sources described a tense and shifting atmosphere, with periods of optimism giving way to deadlock. At one stage, the sides were “80 percent” toward an understanding before unresolved political decisions derailed progress, one source said.

Pakistan played a central mediating role, with Prime Minister Shehbaz Sharif confirming that efforts to bridge differences are ongoing. Officials said communication between Tehran and Washington continues through intermediaries, even after the formal talks ended.

U.S. President Donald Trump said on Monday that Iran had reached out seeking a deal, though this could not be independently verified. A White House spokesperson reiterated that Washington’s position remains unchanged, particularly its demand that Iran abandon any pathway to nuclear weapons.

Iranian officials signaled deep mistrust, citing past negotiations and subsequent military actions, while also indicating willingness to continue discussions under defined conditions.The Strait of Hormuz remains a central point of contention, with Iran asserting control over the waterway and the United States insisting on restoring unrestricted navigation.

The dispute has had significant implications for global energy markets, contributing to volatility and supply concerns.Mediators, including Pakistani officials and regional diplomats, have continued backchannel communications in an effort to revive talks.

Both sides face mounting pressure to de-escalate, with economic costs rising and broader geopolitical risks intensifying.

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.
