Pakistan’s army chief Asim Munir arrived in Tehran on Monday for talks aimed at reviving mediation efforts, as the United States prepared to unveil sweeping new economic measures against Iran.
US Treasury Secretary Scott Bessent has promised what he called the “greatest financial offensive ever” against Iran’s trading partners. He is due to outline the measures at a press conference later on Monday.
Iran has rejected the US threat and warned it could halt all oil exports from the Gulf if what it calls Washington’s “economic war” continues.
Tehran has also issued new warnings to shipping companies over transit through the Strait of Hormuz. Iran said 45 vessels had violated its rules and threatened action against ships conducting transfers with them.
Munir, who has developed a relationship with US President Donald Trump, is visiting Iran as part of Pakistan’s efforts to promote regional peace and stability, according to Islamabad.
A Pakistani source said Munir was expected to meet people close to Iran’s Supreme Leader during his visit.
The diplomatic push comes amid growing tensions between Washington and Tehran, with concerns that further sanctions and disruptions around the Strait of Hormuz could affect global energy supplies.
