Vance Trip for Iran Peace Talks Delayed, Summoned to White House

Compounding pressure on Tehran, the U.S. has enforced a naval blockade on Iranian ports. U.S. Central Command reported that American forces have instructed 28 ships to turn around or return to port. A U.S. official noted that any vessels that managed to enter Iranian ports would be unable to exit past the blockade in the Gulf of Oman.

A two-week ceasefire between the U.S., Israel, and Iran—mediated by Pakistan—is nearing its end, with Iranian participation in the next round of Islamabad talks still unconfirmed. Pakistan’s Information Minister Attaullah Tarar stated late Tuesday that a formal response from Iran was still awaited as of 7:30 p.m. local time. However, Pakistani mediators remain in “constant touch” with Iranian counterparts and have described the talks as “critical” for regional stability.

In a pointed rebuke, Iranian President Masoud Pezeshkian criticized the U.S. approach on X, suggesting American understanding of the situation was lacking. Meanwhile, U.S. Chargé d’Affaires Natalie Baker met with Pakistani Deputy Prime Minister Ishaq Dar to discuss ongoing diplomatic efforts. Dar reiterated Pakistan’s commitment to dialogue, urging both sides to extend the ceasefire and prioritize negotiations.

President Donald Trump has signaled reluctance to simply prolong the truce. “I don’t want to do that. We don’t have that much time,” he told CNBC. Trump expressed hope that Iran could secure a strong deal, allowing it to “make themselves into a strong nation again.”

As the ceasefire deadline looms, the coming days will prove decisive. Success in Islamabad could pave the way for lasting peace, but continued Iranian hesitation risks escalation under sustained U.S. pressure. Pakistan’s mediation role remains central, with both sides facing significant stakes in averting renewed conflict.
