Brazilian President Luiz Inácio Lula da Silva hit back on Monday at recent threats from U.S. President Donald Trump to impose tariffs on countries that align themselves with BRICS. The criticism came during a news conference after the conclusion of the 17th BRICS Summit in Rio de Janeiro, which brought together heads of state and top officials from the bloc's 11 member countries, along with invited partners, for two days of discussions.
