A Pakistani source involved in the negotiations said discussions were “on track” for Wednesday, despite earlier indications from Iran that it might not attend. U.S. President Donald Trump could join the talks either in person or virtually if an agreement is reached, the source added.

U.S. Vice President JD Vance is expected to travel to Pakistan for the переговоры, according to media reports, while Iranian officials said Tehran was “positively reviewing” whether to send a delegation, without confirming participation.

The diplomatic push comes as a two-week ceasefire in the conflict, which began on February 28, nears its end. A Pakistani source said the truce is expected to expire late Wednesday U.S. time.Financial markets reacted to signs of renewed diplomacy, with oil prices falling more than $1 and equities rising in early Asian trading amid expectations that talks could resume.

Brent crude traded near $94 a barrel, while U.S. West Texas Intermediate fell below $88.Tensions remain elevated, however, following disputes over the U.S. blockade of Iranian ports and the recent interception of an Iranian vessel.

Tehran condemned the seizure and warned Washington would bear responsibility for any escalation.Iranian officials also reiterated that they would not negotiate under pressure. Senior figures, including Mohammad Bagher Qalibaf, accused Washington of attempting to force concessions through economic and military pressure.

Washington has said it seeks an agreement that would prevent Iran from developing nuclear weapons while stabilizing energy markets. Tehran, for its part, is seeking relief from sanctions and an end to hostilities without compromising its nuclear program.

The strategic importance of the Strait of Hormuz remains central to the negotiations, as the waterway handles a significant share of global oil and gas shipments and has been affected by restrictions imposed during the conflict.

Pakistan, acting as a mediator, has deployed nearly 20,000 security personnel in Islamabad ahead of the potential talks, underscoring the high stakes and security concerns surrounding the negotiations.

Speaking to reporters aboard Air Force One en route to Washington from Phoenix, Arizona, Trump said the naval blockade on Iranian ports would remain in place regardless of whether the truce is extended. “Maybe I won’t extend it,” he said, adding that without a deal, military operations could resume.

At the same time, Trump struck an optimistic tone about ongoing diplomacy, telling reporters that developments in the Middle East were “going very well” and suggesting a resolution was close. “I think it’s going to happen,” he said, referring to a prospective agreement.

In separate remarks, Trump said there were “no sticking points” remaining in negotiations, describing a deal as “very close,” though he did not provide details on the substance of the talks.The ceasefire, which has paused hostilities between U.S. and Iranian forces, remains fragile amid continued military pressure, including the blockade targeting Iranian ports.

The outcome of negotiations in the coming days is expected to determine whether the truce evolves into a longer-term settlement or collapses, potentially triggering renewed escalation.
