Trump threatens 'tremendous economic consequences' on countries aiding Iran

The announcement comes after the United Arab Emirates, a U.S. ally, announced it was suspending all trade activities, commercial exchanges, and financial transactions with Iran. This move followed the UAE defense ministry's detection of two missiles launched from Iran that fell into the sea, a report Iran dismissed.

Iran's armed forces have also issued a warning to Gulf nations against supporting U.S. forces. Meanwhile, the U.S. and Oman are reportedly engaged in separate negotiations with Tehran concerning the critical Strait of Hormuz, through which a significant portion of global oil and LNG typically passes and which has seen disruptions.

Trump's threats of economic warfare and isolation are part of a broader strategy to pressure Iran, which has endured decades of sanctions. Details on the specific steps the U.S. would take against such countries remain scarce, and no specific nations were named.
