Diplomacy derailed: Vance cancels Islamabad visit as Iran row deepens; Trump extends ceasefire

After much anticipation, the White House on Tuesday announced that Vice President J.D. Vance’s scheduled visit for a second round of talks to Islamabad had been cancelled.

This comes amid escalating tensions between Washington and Tehran over the Strait of Hormuz, which has been largely blocked since February 28, 2026, when the United States and Israel launched an air war against Iran.

In response to this, on April 13, 2026, the United States imposed a naval blockade on Iran following the failure of the Islamabad Talks to end the Iran war, with Trump announcing that the US Navy would blockade the Strait of Hormuz.

In the first 24 hours, CENTCOM reported over 10,000 US personnel, supported by more than a dozen warships and aircraft, enforcing the operation.

Two US aircraft carriers, USS Abraham Lincoln, operating in the Gulf of Oman near the Strait of Hormuz, and USS Gerald R. Ford, reportedly in the Red Sea after transiting the Suez Canal, are currently deployed in the region as part of Washington’s naval blockade of Iran. A third carrier, USS George H.W. Bush, is also reportedly en route.

According to a report by The Wall Street Journal, the US called off J.D. Vance’s visit to Islamabad after Iran did not confirm whether it would participate in the talks. The visit was expected to focus on regional security amid the current tensions in West Asia.

Iranian Foreign Ministry spokesman Esmaeil Baghaei accused Washington of violating the ceasefire citing the April 13 naval blockade and the seizure of an Iranian container ship as breaches of both the truce and international law.

He warned that any renewed US or Israeli aggression would be met with a firm response, and insisted that Tehran’s 10-point proposal from the Islamabad talks remained its basis for negotiation.

“The US is not learning its lessons from experience,” he said. He added that Iran had notified mediator Pakistan of the violations.

Trump extends Iran ceasefire, but pressure tactics remain

Meanwhile, US President Donald Trump announced an extension of the temporary ceasefire with Iran but stressed that core pressure measures would stay intact.

Adding to the escalation, Trump claimed in a Truth Social post that Iran is facing severe financial strain. “Iran is collapsing financially… losing $500 million a day,” Trump said, adding that Tehran is pushing for the Strait of Hormuz to be reopened urgently.

He also alleged that Iran’s military and police forces are not being paid, describing the situation as an “SOS” moment.

He further said that Washington would not lift the blockade of the Strait of Hormuz—a critical global oil transit chokepoint—until both countries reach a final agreement.

In response to this, on Tuesday (April 21, 2026), in a social media post, Iran’s Foreign Minister Abbas Araghchi strongly condemned the US blockade of Iranian ports, calling it an “act of war”.
