ISLAMABAD (AP) — The latest ceasefire talks between the United States and Iran appeared to fail Saturday before they began, as Tehran’s top diplomat left Pakistan and President Donald Trump soon afterward said he had told envoys not to travel to Islamabad.

The negotiations were meant to follow historic face-to-face talks earlier this month between the U.S., led by Vice President JD Vance, and Iran, led by parliament speaker Mohammad Bagher Qalibaf. But Iranian officials have questioned how they can trust the U.S. after its forces started blockading Iranian ports in response to Iran’s war grip on the Strait of Hormuz waterway.

“If they want to talk, all they have to do is call!!!” Trump said on social media, adding: “Too much time wasted on traveling, too much work!” The White House on Friday said Steve Witkoff and Jared Kushner would be going to Islamabad.

Iran’s Foreign Minister Abbas Araghchi left Islamabad on Saturday evening, two Pakistani officials told The Associated Press, speaking on condition of anonymity because they were not authorized to talk to the media.

“Shared Iran’s position concerning workable framework to permanently end the war on Iran. Have yet to see if the U.S. is truly serious about diplomacy,” Araghchi later said on social media.

Another ceasefirebetween Israel and the Iranian-backed Hezbollah, was shaken Saturday as each side fired at the other and Israeli Prime Minister Benjamin Netanyahu ordered the military to “vigorously attack Hezbollah targets in Lebanon.”

Iran had said any talks would be indirect

Trump this week announced an indefinite extension of the ceasefire with Iran. It has paused most fightingbut the economic fallout is growing two months into the war as global shipments of oil, liquefied natural gas, fertilizer and other supplies are disrupted by the near-closure of the Strait of Hormuz.

Both sides have continued to make military threats. Iran’s joint military command on Saturday warned that “if the U.S. continues its aggressive military actions, including naval blockades, banditry, and piracy” it will face a “strong response.”

Even before Saturday’s developments, Iran’s foreign ministry said any talks would be indirect and that Pakistani officials would convey messages. In Pakistan, Araghchi met with Army Chief Field Marshal Asim Munir and Prime Minister Shehbaz Sharif about what he called Iran’s red lines for negotiations.

Araghchi went on to Oman, a mediator in talks before the war and the country on the other side of the Strait of Hormuz. The foreign minister will visit Pakistan again on Sunday before visiting Russia, the state-run IRNA news agency reported.

Trump later told journalists that within 10 minutes of him canceling the envoys’ trip to Pakistan, Iran sent a “much better” proposal, with no details. He stressed that one of his conditions is that Iran “will not have a nuclear weapon.”

Contentious points in talks include Iran’s enriched uranium and the standoff on the Strait of Hormuz as well as concerns about Iran’s missile program and its support for armed proxies in the region.

Tehran has noted that indirect talks with the U.S. last year and early this year over its nuclear program, the issue long at the center of tensions, ended with Iran being attacked by the U.S. and Israel, adding to its wariness.

The standoff around the strait continues

The price of Brent crude oil, the international standard, is nearly 50% higher than when the war began because of Iran’s grip on the strait, through which a fifth of the world’s oil passes in peacetime.

Iran attacked three ships this week, while the U.S. maintains a blockade on Iranian ports. Trump has ordered the military to “shoot and kill” small boats that could be placing mines.

Germany’s Defense Minister Boris Pistorius said his country was sending minesweeper ships to the Mediterranean to help remove Iranian mines from the strait once hostilities end.

Also Saturday, Iran resumed commercial flights from Tehran’s international airport for the first time since the war began with U.S. and Israeli strikes on Feb. 28. Flights were scheduled to depart for Istanbul, Oman’s capital of Muscat and the Saudi city of Medina, according to state-run television.

A growing toll even as ceasefires hold

Since the war began, authorities say at least 3,375 people have been killed in Iran and at least 2,496 people in Lebanon, where new fighting between Israel and the Iran-backed militant group Hezbollah broke out two days after the Iran war started.

Trump announced Thursday that Israel and Lebanon had agreed to extend a ceasefire between Israel and Hezbollah by three weeks. Hezbollah has not participated in the Washington-brokered diplomacy.

But Israel struck southern Lebanon on Saturday, killing at least six people it aid were Hezbollah militants, and several rockets and drones were launched at Israel from Lebanon.

Additionally, 23 people have been killed in Israel and more than a dozen in Gulf Arab states. Fifteen Israeli soldiers in Lebanon, 13 U.S. service members in the region and six members of the U.N. peacekeeping force in southern Lebanon have been killed.

WASHINGTON (AP) — President Donald Trump’s administration is placing economic sanctions on a major China-based oil refinery and roughly 40 shipping companies and tankers involved in transporting Iranian oil.

The move, announced Friday and first reported by The Associated Press, makes good on Trump’s threat to impose secondary sanctions on companies and countries that do business with Iran. It’s also part of his Republican administration’s overall ramped-up campaign to cut off Iran’s key source of revenue — its oil exports.

Concurrently, the U.S. this month imposed a physical blockade on the Strait of Hormuzthe Persian Gulf waterway that is crucial to global energy supplies.

The sanctions, which cut off the companies from the U.S. financial system and penalize anyone who does business with them, come just a few weeks before President Donald Trump and China’s Xi Jinping are due to meet in China.

Included in Friday’s sanctions is Hengli Petrochemical’s facility in the port city of Dalian, which has a processing capacity of roughly 400,000 barrels of crude oil per day, making it one of the biggest independent refineries in China.

The Treasury Department says Hengli has received Iranian crude oil shipments since 2023 and has generated hundreds of millions of dollars in revenue for the Iranian military.

The advocacy group United Against Nuclear Iran said in February 2025 that Hengli is one of dozens of Chinese purchasers of Iranian oil.

China is the biggest buyer of Iranian oil, importing 80% to 90% of Iranian oil before the U.S.-Israeli war with Iran broke out, though the crude — transported by a shadow fleet of vessels — often has its origin obscured but arrives in China as oil from countries such as Malaysia. Smaller refineries, known as teapot refineries, typically are the buyers of Iranian oil.

Iran has previously said that its demands for ending the war include the lifting of sanctions.

Treasury Secretary Scott Bessent said Friday that his agency “will continue to constrict the network of vessels, intermediaries and buyers Iran relies on to move its oil to global markets.”

Earlier this month, Bessent’s department sent a letter to financial institutions in China, Hong Kong, the UAE and Oman threatening to levy secondary sanctions for doing business with Iran and accusing those countries of allowing Iranian illicit activities to flow through their financial institutions.

Bessent said during a White House press briefing on April 15 that the administration has told countries “that if you are buying Iranian oil, that if Iranian money is sitting in your banks, we are now willing to apply secondary sanctions, which is a very stern measure.”

The sanctions come as the global energy trade is in turmoil as war around the Persian Gulf chokes off oil and natural gas shipments, causing prices to soar.

Treasury has tried to quell the impact of rising oil prices issuing temporary sanctions waivers on Russia oil and a one-time waiver on Iranian oil already at sea.

The AP was making efforts to contact Chinese officials for comment on the sanctions.

China has disagreed with previous U.S. sanctions, but its major companies and banks still comply with U.S. sanctions because they are more exposed to the U.S.-dominated financial system.

After the U.S. earlier this month sanctioned a Chinese refinery accused of buying Iranian oil, Liu Pengyu, a spokesperson for China’s embassy in Washington, said the use of the sanctions “undermines international trade order and rules, disrupts normal economic and trade exchanges, and infringes upon the legitimate rights and interests of Chinese companies and individuals.”
