‘Tariff war will start when I respond to Trump,’ says Lula in Chile. The statement to journalists was made on Monday, 21, during the president's participation in a summit of Latin American leaders. Lula denied that he is in a tariff war with the United States: “It will start when I respond to Trump, if he does not change his mind.” The president also avoided commenting on the restrictive measures imposed by Alexandre de Moraes on Jair Bolsonaro: “It’s a problem of the Justice, I won’t give my opinion.”
