Tensions between the United States and Brazil have suddenly burst open. Brazil’s president promised to reciprocate against President Trump’s tariffs.

RIO DE JANEIRO (AP) — Brazilian President Luiz Inácio Lula da Silva said Thursday that he will impose retaliatory tariffs on the United States if President Donald Trump follows through on a pledge to boost import taxes by 50% over the South American country’s criminal trial against his predecessor, Jair Bolsonaro.

US-Brazil relations took a sharp downturn Monday after US President Donald Trump criticised the coup trial of his right-wing ally, ex-president Jair Bolsonaro, calling it a "witch hunt" and urging authorities to "leave Bolsonaro alone".
