Trump Imposes 25% Tariffs on Countries Doing Business with Iran as Standoff Grows

U.S. President Donald Trump announced on Monday a sweeping new economic measure — imposing a **25 percent tariff on any country that does business with Iran — as tensions continue to escalate over the violent crackdown on nationwide protests there.

In a post on social media, Trump declared the tariff “effective immediately” and “final and conclusive,” warning that nations trading with Tehran — including major partners such as China, India, Turkey, and the United Arab Emirates — will face increased costs on their exports to the United States.

The move comes as Trump weighs a “range of options,” including potential military action against Iran, citing the country’s deadly suppression of widespread anti-government demonstrations. Tehran, meanwhile, says it is still communicating with Washington despite the standoff.

Economists warn that the tariff could reverberate through global markets, potentially sparking trade disputes and supply chain disruptions if impacted countries retaliate. At the same time, the policy underscores the growing use of economic tools — alongside diplomatic pressure — in shaping U.S. foreign policy.

Officials have offered few details about how the new tariff regime will work, which industries will be targeted, or how long it could remain in place. For now, the announcement adds another layer of complexity to an already volatile international landscape where economic pressure and military threats are intersecting.
