WRAPUP 3-Mediator Pakistan to hold talks in Iran on US 'economic D-Day'

Pakistan's army chief was visiting Tehran on a mediating mission on Monday as the United States prepared to roll out "the greatest financial offensive ever" targeting Iran's trade partners. Iran dismissed the U.S. threat, vowing to shut down all oil exports from the Gulf "if the economic war continues" and ‌issued a new warning to shipping not to pass through the Strait of Hormuz without its permission.

U.S. Treasury Secretary Scott Bessent has promised to reveal severe measures on Iran, which has endured near-continuous economic sanctions since the Islamic Revolution of 1979, when he gives a press conference at 1 p.m. EDT (1700 GMT) on Monday. "At dawn begins an economic D-Day — the single greatest financial offensive ever marshalled against an adversary," Bessent wrote in an opinion piece published in the Financial Times on Sunday.

Pakistan's army chief Asim Munir, who has built a personal rapport with U.S. ‌President Donald Trump, arrived in Iran for talks, Iranian media said. Pakistan said the visit was part of its efforts "to promote regional peace and stability", and a Pakistani source said Munir was expected to meet people close to Iran's supreme leader. Tehran has said ‌Oman's foreign minister will visit on Tuesday to discuss the Strait of Hormuz.

PROJECTILE HITS TANKER NEAR SAUDI RED SEA PORT, MONITORS SAY The U.S. and Iran have not conducted strikes against each other's militaries for weeks, but their last official face-to-face talks to end the six-month-old conflict took place in June and strikes on vessels in the Strait of Hormuz have continued.

A projectile struck a tanker west of the Saudi port city of Yanbu in the Red Sea on Monday, causing a fire on the main deck, shipping monitors from the United Kingdom Maritime Trade Operations said. They did not say who had launched the projectile. Iran's Houthi allies last month ⁠said they would block ​Saudi oil exports diverted to the Red Sea to avoid Hormuz. Thousands ⁠of people have died, most of them in Iran and Lebanon, since the U.S. and Israel began strikes on February 28, degrading much of Iran's conventional military capacity and inflicting economic pain while killing Iran's then-Supreme Leader Ayatollah Ali Khamenei.

But Iran has preserved enough missile and drone capability to attack its Gulf neighbours and ⁠threaten oil tankers in the Strait of Hormuz, bringing shipping in the key waterway to a near standstill and pressuring world fuel prices. The exact state of Iran's nuclear program, which the Americans and Israelis aim to wipe out, remains unknown. Oil prices slipped more than $1 a barrel on Monday as investors took ​profits ahead of the expected U.S. announcement.

Without detailing specific measures, Bessent signalled the U.S. would target "fearful nations" that practice "appeasement" by engaging with Iran's economy and financial system. "They would do well to consider the consequences of sustaining it," he wrote ⁠in the Financial Times.

Iran has been bracing for the sanctions for days, issuing a series of strongly worded statements hinting at a major military response. Mohsen Rezaei, secretary of Iran's Supreme National Security Council, on Sunday suggested economic retaliation.

"If the economic war continues, not a single drop of oil will be exported, neither through the Strait of ⁠Hormuz ​nor from anywhere in the Persian Gulf," Rezaei wrote in a social media post. "Iran will regard any country’s participation in or support for America’s economic war against the Iranian people as an act of war." CHINA SAYS SANCTIONS AND PRESSURE TACTICS WILL NOT WORK

Bessent previously urged China to cooperate with the U.S., noting China historically has received half of its oil imports from the Gulf region. China's foreign ministry said on Monday that sanctions and pressure tactics do not help resolve issues and that Beijing would do what was necessary ⁠to protect the country's interests. Iran's Deputy Foreign Minister Kazem Gharibabadi dismissed the latest moves from Washington, which has said the measures will bring down the Iranian government, saying the U.S. has been promising Iran's end for 48 years, "each time under a new name".

"Iran has ⁠remained steadfast and powerful, and only the names of the failed projects ⁠have changed," he said on X. Iran's economy was already under pressure from international sanctions before the U.S. and Israeli attacks destroyed parts of its infrastructure.

Though Tehran remains outwardly defiant, Iranian officials who spoke to Reuters have expressed concern that further economic punishment could increase hardships, reignite unrest and further erode the Islamic Republic's legitimacy. Iran entered the war with high inflation, a weakening currency, energy shortages, sanctions ‌and deep structural weaknesses, and must now contend ‌with damaged infrastructure, disrupted trade, lost production and the cost of rebuilding.
