• Trump announces a 25% tariff on countries trading with Iran.
• The tariff is effective immediately and deemed "final and conclusive."
• Major economies like China and India are expected to be heavily impacted.

President Donald Trump declared on Monday that any country engaging in trade with Iran will face a 25% tariff on any business interactions with the United States. This measure, aimed at increasing pressure on Tehran amid ongoing protests, is highlighted by Trump as "effective immediately" and "final and conclusive," according to CBS News and Reuters.

This new tariff impacts a range of countries, especially those with significant trade relationships with Iran like China, India, and the United Arab Emirates. The President's announcement comes amid his threats of military action against Iran if it does not cease violent crackdowns on protesters, as reported by Business Insider and BBC.

The tariffs have been positioned as part of a broader strategy against Iran’s military ambitions and its treatment of peaceful demonstrators, which has drawn international scrutiny. White House Press Secretary Karoline Leavitt noted that the administration has not ruled out further military options, according to SCMP and Al Jazeera.

As unrest continues in Iran, human rights organizations have documented significant casualties among protestors, contributing to the urgency of Trump's decision, which affects a wide range of nations engaged economically with Iran, including Russia and Turkey, as mentioned by India Times.
