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.S. dollar.

“The idea that the BRICS Countries are trying to move away from the Dollar while we stand by and watch is OVER,” Trump wrote. “We require a commitment from these Countries that they will neither create a new BRICS Currency, nor back any other Currency to replace the mighty U.S. Dollar or, they will face 100% Tariffs, and should expect to say goodbye to selling into the wonderful U.S. Economy.”
