The president-elect's threat comes just days after he threatened big tariffs on Mexico, Canada and China. Experts warn of higher prices.

In a post on Truth Social Saturday, President-elect Donald Trump said he would impose a 100% tariff on the BRICS geopolitical coalition of non-Western countries if the group moves away from trading using the U.

Trump also said in his post that the countries "can go find another “sucker!” There is no chance that the BRICS will replace the U.S. Dollar in International Trade, and any Country that tries should wave goodbye to America.
