Trump Announces Immediate 50% Tariffs on Any Country Supplying Military Weapons to Iran — Targeting China and Russia

Hours after reaching the Iran ceasefire deal, President Trump announced via Truth Social that any country supplying military weapons to Iran would face an immediate 50% tariff on all goods sold to the United States, with "no exclusions or exemptions." The announcement was widely interpreted as targeting China and Russia, the two primary suppliers of military technology to Iran throughout the conflict. Trump said the tariff would apply "immediately" and stated: "A Country supplying Military Weapons to Iran will be immediately tariffed, on any and all goods sold to the United States of America, 50%, effective immediately. There will be no exclusions or exemptions!" Trump did not specify the legal authority for the tariffs — a significant omission given the Supreme Court's February 2026 ruling striking down his use of IEEPA for broad global tariffs. South China Morning Post reported that Trump simultaneously lauded Beijing's role in facilitating the Iran ceasefire even as he issued the tariff threat. The announcement came amid an already fractious US-China trade relationship: China's 34% retaliatory tariff on all US goods had just taken effect and 145% cumulative US tariffs on Chinese imports remained in place.
