President Donald Trump said the U.S. will impose an additional 10% tariff on any countries aligning themselves with the "Anti-American policies" of the BRICS group of developing nations, whose leaders kicked off a summit in Brazil on Sunday.

Trade and tariffs will be high on the agenda for the upcoming BRICS Summit in Brazil, but geopolitical divisions and conflict could be distractions.

"Any Country aligning themselves with the Anti-American policies of BRICS, will be charged an ADDITIONAL 10% Tariff. There will be no exceptions to this policy. Thank you for your attention to this matter!
