Trump dials up risky Iran tariffs that would hit China, UAE and others: What to know

Any country trading with Iran now faces a 25% tariff, per the White House, but the move is unlikely to ratchet up pressure on Tehran in the short term.

As protests rock Iran and the regime responds with lethal force, US President Donald Trump is signaling he wants to escalate economic pressure on Tehran as Washington considers how to respond to the Islamic Republic’s most serious unrest in years.

On Jan. 12, Trump said that any country trading with Iran would face a 25% tariff on “any and all business” with the United States, adding that the move would take effect “immediately.” The White House hasn’t yet provided details on how such a tariff would be implemented, but the move would have significant consequences for China and Iran’s other top trading partners, including the United Arab Emirates, Turkey, Iraq and others.
