Brazilian President Luiz Inácio Lula da Silva says he will impose retaliatory tariffs on the United States if President Donald Trump follows through on a pledge to boost import taxes by 50%

Brazil’s President forcefully rebuked Trump after the U.S. leader called the prosecution of Lula’s predecessor, Bolsonaro, a “witch hunt” and hiked tariffs on the Latin American nation.

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.
