U.S. President Donald Trump said on Tuesday the U.S. would "pretty soon" charge a 10% tariff on imports from BRICS countries, drawing another complaint from Brazil President Luiz Inacio Lula da Silva,

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.

Developing nations at the BRICS summit on Monday brushed away an accusation from President Donald Trump that they are "anti-American," with Brazil's president saying the world does not need an emperor.
