US 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 US dollar and repeated threats to levy a 100% tariff.

President-elect Trump on Saturday threatened the developing countries known the the BRICS bloc with "100% tariffs" if they try to move away or replace the dollar.

Trump is threatening 100% tariffs against a bloc of nine nations including Brazil, Russia, India, China and South Africa if they act to undermine the U.S. dollar.
