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.

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

While China could offset American tariffs by letting its currency fall, that might endanger Beijing’s recent efforts to stabilize the economy.
