Talks Between Washington and Tehran Remain Active Despite Gaps

U.S. and Iranian negotiations remained active after their highest-level talks in decades ended in Islamabad without a breakthrough, though backchannel engagement continues. The talks, held over more than 20 hours at Islamabad’s Serena Hotel with Pakistan mediating, brought together U.S. Vice President JD Vance, Iranian Parliamentary Speaker Mohammad Baqer Qalibaf and Foreign Minister Abbas Araqchi.

Despite no agreement, several sources said the sides came close, with one describing them as “80% there” before unresolved issues halted progress. Key disputes centred on Iran’s nuclear programme, sanctions, and the Strait of Hormuz, a major energy route Iran has effectively blocked and the U.S. has pledged to reopen.

The atmosphere shifted throughout. Two Iranian sources described it as tense and unfriendly, though slightly improved by early Sunday. A U.S. source said Iranian officials did not fully grasp Washington’s core demand that Iran must never obtain a nuclear weapon, while Tehran remained distrustful of U.S. intentions.

Most substantive exchanges involved Vance, Qalibaf and Araqchi, with Pakistani officials shuttling between sides to maintain momentum. Phones were barred in the main room, forcing delegates to step out during breaks to relay messages.

The two sides also differed on scope: the U.S. focused on nuclear limits, Hormuz access and regional security guarantees, while Iran sought sanctions relief, a permanent ceasefire, frozen asset access and recognition of enrichment rights.

Despite the deadlock, U.S. Vice President Vance said diplomacy remains open. “We leave here with a very simple proposal, a method of understanding that is our final and best offer,” he said.

Businesses in energy, shipping and finance sectors are closely monitoring the talks, as any progress could ease pressure on global oil prices and trade routes through the Strait of Hormuz.

Overall, although the high-level talks in Islamabad did not yield a breakthrough, the continuation of backchannel engagement suggests that diplomatic efforts between Washington and Tehran remain active despite significant gaps.
