Trump signs executive order threatening tariffs for countries trading with Iran

President Donald Trump has signed an executive order that allows the United States to impose sanctions on countries that continue to do business with Iran. The order does not specify the exact tariff rate that could be imposed, but it uses 25% as an example. The move is part of the Trump administration's "maximum pressure" campaign against Iran, which aims to further isolate the country economically and diplomatically. The executive order gives the Treasury Department the authority to impose sanctions on foreign financial institutions that knowingly facilitate significant transactions with Iran. The order is intended to discourage countries and companies from engaging in economic activities with Iran, which the United States has accused of supporting terrorism and pursuing nuclear weapons. The decision comes amid heightened tensions between the US and Iran, following the US withdrawal from the 2015 nuclear deal and the imposition of tough economic sanctions on the Iranian regime.
