The US announced "Operation Economic Outcast," a comprehensive secondary sanctions campaign targeting Iran's financial networks and supply chains, threatening to exclude foreign entities and even China from the dollar system if they conduct transactions with Iran. Treasury Secretary Scott Bessent stated the plan targets 60+ entities across five key sectors (digital assets, technology, gold, aviation, shipping), and warned that no country—including major trading partner China—will be exempt. The move signals an aggressive economic warfare strategy but experts note it represents a "warning shot" rather than full enforcement.
