Trump announces 25% tariff on countries that do business with Iran

US President Donald Trump on Monday said he has imposed a 25% tariff on goods from countries with commercial ties to Iran, a move that could put pressure on Tehran as anti-government protests enter a third week.

Trump said on social media that the tariff was “effective immediately”, without offering details of what constituted “doing business” with Iran.

China is among Iran’s largest trading partners, along with the United Arab Emirates, India and Turkey.

The new tariff comes after Trump threatened to intervene militarily if Tehran killed protesters. White House spokeswoman Karoline Leavitt said on Monday that military options including air strikes were still “on the table”.
