On February 26th, Trump stated that the US has decided to impose a 25% tariff on the EU and will announce it "soon". On the 25th, Trump also ordered a new investigation into possible new tariffs on copper imports to rebuild copper production in the United States.

On February 27th local time, US President Trump announced that the tariffs he proposed to impose on Mexico and Canada would take effect as scheduled on March 4th, while tariffs on Chinese goods would also increase by an additional 10% on the same day.

This means that after Trump takes office, on top of the 10% tariffs that have already taken effect earlier this month, the United States will once again wield the baton of tariffs on China. If Trump implements the above statement, by March 4th, the Trump administration's cumulative tariffs on China will reach 20%.

On February 1st, Trump signed an executive order announcing the imposition of a 10% tariff on all goods imported from China, based on the International Emergency Economic Powers Act (IEEPA), citing issues such as fentanyl.

At that time, Trump also announced that the United States would impose a 25% tariff on goods imported from Mexico and Canada, including a 10% tariff on energy resources from Canada, but the implementation was postponed for one month. Subsequently, Trump also announced a 25% tariff on all steel and aluminum imports to the United States, as well as additional tariffs on automobiles, semiconductors, pharmaceuticals, and timber.
