U.S. President-elect Donald Trump warned the so-called BRICS nations that he would require commitments that they would not move to create a new currency as an alternative to using the U.S. dollar and repeated threats to levy a 100% tariff.

"The idea that the BRICS Countries are trying to move away from the Dollar while we stand by and watch is OVER,” Trump said in a post to his Truth Social network on Saturday.

"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,” he added.
