The Japan Times - Iran not planning to attend talks with US in Pakistan

The ongoing US blockade of Iranian ports has been a significant sticking point, and that issue is likely to be further complicated by Trump's Sunday announcement that an American destroyer had fired on and hit an Iranian ship that tried to evade it.

State broadcaster IRIB on Sunday cited Iranian sources as saying "there are currently no plans to participate in the next round of Iran-US talks".

The Fars and Tasnim news agencies had earlier cited anonymous sources as saying "the overall atmosphere cannot be assessed as very positive", adding that lifting the US blockade was a precondition for negotiations.

State-run IRNA meanwhile pointed to the blockade and Washington's "unreasonable and unrealistic demands", saying that "in these circumstances, there is no clear prospect of fruitful negotiations".

Iran and the United States, along with Israel, are just three days away from the end of the two-week ceasefire that halted the Middle East war, ignited by surprise US-Israeli strikes on Iran on February 28.

There has so far been only a single, 21-hour negotiating session held in Islamabad on April 11 that ended inconclusively, though groundwork for fresh talks continued afterwards.

"We're offering a very fair and reasonable DEAL, and I hope they take it," Trump said in a post on Sunday, while also renewing his threats against Iran's infrastructure if a deal is not made.

Trump has been under pressure to find an off-ramp since Tehran moved early in the war to choke off the Strait of Hormuz.

The vital waterway is a conduit for a fifth of the world's oil and liquefied natural gas in peacetime, and its closure has hammered the global economy and roiled markets.

Having failed to force it open again, Trump countered with a US naval blockade on Iranian ports in an attempt to cut off Tehran's oil revenues.

On Sunday, he announced that a massive Iranian-flagged cargo ship "tried to get past our Naval Blockade, and it did not go well for them."

A US destroyer warned the ship to stop and then forced it to by "by blowing a hole in the engineroom", Trump said, adding: "Right now, U.S. Marines have custody of the vessel."

Trump said the Iranian-flagged ship, Touska, is under US Treasury sanctions "because of prior history of illegal activity."

Iran had briefly reopened the strait on Friday in recognition of an Israel-Hezbollah ceasefire in Lebanon, but closed it again the following day in response to the United States maintaining its blockade.

Iran's Revolutionary Guards warned that any attempt to pass through the strait without permission "will be considered cooperation with the enemy, and the offending vessel will be targeted".

Iranian foreign ministry spokesman Esmaeil Baqaei on Sunday said the blockade was "a violation" of the ceasefire and illegal collective punishment of the Iranian people.

A handful of oil and gas tankers had crossed the strait early on Saturday during the brief reopening, but by early Sunday morning tracking data showed the waterway empty of shipping.

The afternoon before, a trio of incidents involving Iranian fire and threats towards commercial vessels demonstrated the danger of any attempted crossing.

- Heightened security -

In spite of the uncertainty surrounding the talks in Pakistan, security was visibly stepped up in Islamabad on Sunday in anticipation of the negotiations.

Authorities announced road closures and traffic restrictions across the city, as well as in neighbouring Rawalpindi.

"Citizens are earnestly requested to cooperate with the security agencies," a city official posted on X.

The US president said his negotiators, whom he did not name, would arrive in the Pakistani capital on Monday evening.

A White House official said the delegation would be led by Vice President JD Vance and include Middle East envoy Steve Witkoff and Trump's son-in-law Jared Kushner.

A major issue in the negotiations has been Iran's stockpile of near-weapons-grade enriched uranium.

Trump said on Friday that Iran had agreed to hand over its roughly 440 kilogrammes of enriched uranium. "We're going to get it by going in with Iran, with lots of excavators," he said.

But Iran's foreign ministry has said the stockpile, thought to be buried deep under rubble from US bombing in last June's 12-day war, was "not going to be transferred anywhere", and surrendering it "to the US has never been raised in negotiations".

On Sunday, President Masoud Pezeshkian questioned why Iran should give up its "legal right" to a nuclear programme.
