President Donald Trump is imposing 25% tariffs against countries that are trade partners with Iran amid a warning he’s made to Tehran related to using force to contain ongoing protests.

President Donald Trump has once again drawn his go-to diplomatic weapon — tariffs — to coerce the Iranian government to end its bloody crackdown on nationwide protests.

“Effective immediately, any Country doing business with the Islamic Republic of Iran will pay a Tariff of 25% on any and all business being done with the United States of America,” Trump posted on Truth Social Monday night. “This Order is final and conclusive.”

Protests broke out against clerical rulers who've run Iran since the Islamic Revolution in 1979, but were met with severe punishment

President Donald Trump has arrived at a delicate moment as he weighs whether to order a U.S. military response against the Iranian government over its crackdown on protests.

Trump said the tariff would apply “effective immediately” to any country trading with Iran while also doing business with the United States, calling the order “final and conclusive”.
