The short version

Iran's Supreme National Security Council leader Mohsen Rezaei warned regional neighbors that supporting new U.S. economic measures would be treated as an act of war, threatening to strike alternative Persian Gulf oil transit routes.
U.S. Treasury Secretary Scott Bessent is scheduled to announce a severe economic isolation offensive against Iran, promising heavy financial penalties for countries maintaining ties with Tehran.
International reactions remain split, with the UAE halting financial ties with Iran while China criticizes the pressure campaign and foreign delegations attempt diplomatic mediation.
It remains uncertain how strictly the U.S. will enforce secondary sanctions against major buyers of Iranian oil like China and whether the measures can alter Tehran's regional posture.
