ConflictDeveloping

Key takeaway

Pakistan is relaying corrective points between Tehran and Washington, yet neither side has produced a signed counter-text.

Esmail Baghaei, the Iranian Foreign Ministry spokesman, confirmed on 20 May 2026 that the Pakistan-mediated channel remains active ¹. "We received a set of corrective points and considerations from the Pakistani mediator," Baghaei said. "Our points of view were presented to the American side in return. Therefore, the process continues through Pakistan."

Baghaei's confirmation marks the third documented exchange in the sub-cycle. Iran transmitted a 10-point counter-MOU on 10 May; Donald Trump rejected it on Truth Social as "totally unacceptable"; Pakistan has now relayed a fresh round of corrective points in return. Neither side is working from a shared text; both are annotating each other's positions.

Tasnim also reported on 18 May that the US had agreed in a new text to suspend oil sanctions during the negotiation period. The claim cites an anonymous source close to Iran's negotiating team and has no US-side corroboration: no executive order on 19-20 May, no OFAC general licence, no Federal Register entry, no White House action covered the zero-instrument count across 16-18 May; the 19-20 window extends the streak. The OFAC SDN round on 19 May targeted vessels and shells , not a sanction suspension. The Senate's procedural discharge of the Kaine resolution deadline opened the political vulnerability the verbal track has not yet answered with paper.

Deep Analysis

In plain English

Pakistan is acting as a go-between in the US-Iran negotiations. Iran talks to Pakistan, Pakistan tells the US, the US responds, Pakistan tells Iran. The two sides have never met face-to-face. On 20 May, Iran's Foreign Ministry spokesman confirmed this channel is still working: Pakistan has delivered a new set of suggested changes from the US side. Iran has sent its own response back. But neither side has yet agreed on a shared document they are both working towards. Iran's state news agency also claimed the US has agreed to pause oil sanctions during negotiations. As of 20 May, no US official has confirmed this and no document to that effect has appeared.

Deep Analysis

Root Causes

Pakistan mediates because it is one of the few states with simultaneous institutional credibility in Washington (military-to-military ties, CENTCOM interoperability) and Tehran (border relationship, Baloch population, energy imports from Iran). Field Marshal Munir's personal credibility with both IRGC leadership and the Trump administration's senior military figures gives him a contact network no career diplomat could replicate.

The channel's structural limitation is that Pakistan cannot bridge the gap between Iran's demand for domestic uranium stockpile dilution (rather than transfer) and the US demand for physical removal outside Iran. That is a technical nuclear-verification problem, not a diplomatic communication problem; no intermediary can resolve it without an IAEA inspection regime, which Iran's Majlis voted 221-0 to suspend.

What could happen next?

Risk
The Tasnim oil-sanctions waiver claim, if false, sets Iranian domestic expectations that the US will not meet; a public US denial of the claim would damage the channel's credibility faster than any formal breakdown.
Immediate · 0.7
Consequence
Three sub-cycle exchanges since 10 May without converging on shared text means the gap is structural (document count, framework) rather than positional (terms within a shared document); a fourth exchange in the same format is unlikely to resolve it.
Short term · 0.75
Opportunity
Pakistan's Asim Munir secured Iran's in-principle nuclear-monitoring concession in April through informal assurances outside the written text. A similar informal side-agreement on sanctions modalities may be where the real settlement lies, with formal documents following later.

Source Landscape

This story draws on mixed-leaning sources from Iran

Iran

LeftRight

Primary parallel: The Algiers Accords of 19 January 1981 ended the Iran hostage crisis after 15 months of indirect US-Iran negotiation mediated entirely by Algeria, which relayed documents between Washington and Tehran without the parties ever meeting face-to-face.

The Algerians were instructed not to bridge the gap but to translate positions accurately; the resolution came when both sides simultaneously accepted a text they had each individually modified. The Pakistan channel in 2026 follows the same structural pattern.

Counter-parallel: During the 2003 'Grand Bargain' attempt, Iran transmitted a comprehensive proposal to Washington through Swiss intermediaries offering to end support for Hamas and Hezbollah, accept the Arab Peace Initiative, and cooperate on nuclear transparency. The State Department never formally responded; the intermediary channel atrophied. The 2026 Pakistan channel has produced more exchanges than the 2003 Swiss attempt, but neither side has yet accepted a shared document.

Consensus view: IISS's Emile Hokayem and International Crisis Group's Ali Vaez assess the third sub-cycle exchange as evidence that Pakistan's mediation has become a mail relay rather than a bridging function. Both parties are annotating each other's positions rather than converging on shared text; the 10-point versus 14-point document count gap (Iran's counter vs the US MOU) means they are working from different frameworks, not different positions on the same framework.

Counter-view: Islamabad-based Strategic Vision Institute's Zafar Khan argues Pakistan's role has already exceeded its declared mandate: Field Marshal Asim Munir extracted Iran's first in-principle nuclear-monitoring concession in April, a structural commitment that did not appear in any of the subsequent written exchanges. The Pakistan channel may be producing substantive progress on informal assurances that the published text count does not capture.

Key tension: Whether the Tasnim-reported US oil-sanctions waiver reflects a real informal understanding transmitted via Pakistan that neither side is prepared to put in writing, or whether it is Iranian state media positioning for domestic audience management ahead of the WPR floor vote.

Different Perspectives

China

Beijing's MOFCOM Blocking Rules constrain OFAC enforcement on the mainland; China has not corroborated Trump's verbal account of any bilateral summit, and the rial's failure to hold its Rubio bounce, combined with the IRGC's stablecoin rail closure, increases Chinese yuan-denominated oil-payment exposure through Hormuz.

Israel

IDF Chief Zamir said on 3 June there is no ceasefire for his forces even as Israel signed the Washington Lebanon framework requiring Hezbollah withdrawal south of the Litani; a UNIFIL peacekeeper was killed by mortar near Marjayoun on the same day, exposing the gap between the diplomatic framework and a ground advance that has not stopped.

Bahrain

The IRGC struck Bahrain on 3 June as its sirens sounded and its PAC-3 magazine neared exhaustion; excluded from Rubio's 2 May emergency resupply, Bahrain received a 50-round Federal Register notice on 1 June on an 18-month delivery timeline, meaning it is defending the US Fifth Fleet headquarters on the last rounds it has.

Qatar

Qatar offered $6bn under OFAC Licence L-2 restrictions and sent Ghalibaf's delegation home empty-handed; the $6bn ceiling is a legal constraint, not a negotiating floor, and Rubio's no-sanctions-relief testimony means Qatar cannot revise it without White House action that has not been requested.

Kuwait

Kuwait expelled two Iranian diplomats within 24 hours of the airport strike, the strongest and fastest Kuwaiti diplomatic move of the conflict, while keeping the full mission in place to preserve a communication channel; it has now invoked Article 51 self-defence, filed a formal protest, and expelled diplomats, exhausting its formal toolkit short of full rupture.

United States

Trump narrated a weekend deal while the channel Rubio described under oath, Khamenei's written-only couriers with a 3-to-5-day lag, cannot answer at that speed; CENTCOM called the airport strike deliberate, calculated and unjustified. The House 215-208 vote gave Congress its first on-record war-powers position against the deployment Trump has run without a signed instrument for 96 days.
