Argentina After Repeated Insults by President Javier Milei Against Brazilian President Luiz Inácio Lula da Silva and the Supreme Federal

The Foreign Ministry decided that Brazil's ambassador in Buenos Aires, Julio Bitelli, will not return to Argentina while Milei's attacks continue, deeming the insults an unacceptable disrespect in bilateral ties. Brazil will now be represented in Argentina by a chargé d'affaires, a lower-ranking post reflecting the diplomatic downgrade. On July 26, Bitelli was recalled to Brasília after Milei called Lula a "convict" and attacked STF Justice Alexandre de Moraes at a Liberal Party (PL) convention that nominated Senator Flávio Bolsonaro for the presidency.

The convention came after Moraes presided over the case that sentenced Flávio's father, former President Jair Bolsonaro, to 27 years in prison for an attempted coup. The Itamaraty said in a statement, "There is no precedent for a foreign president who, on national territory, bundles aggressions and offenses against the Head of State, democratic institutions, including the Judiciary, and the Brazilian people. In the days following the PL convention, Milei continued insulting Lula with terms like "thief" and "socialist trash, and also kept attacking the STF in public appearances.

These repeated aggressions prompted Brazil to keep Bitelli out of Argentina until the insults stop. Argentina's government lamented the "unilateral" decision, calling it "purely ideological, with its Foreign Ministry saying, "We never respond to a political difference with an institutional measure. That is the criterion Argentina maintains today.

Brazil has countered that it maintains diplomatic ties with governments of all ideological profiles, with the offenses being the reason for the downgrade. The decision drew reactions in Argentine media: Clarín called it a "harsh diplomatic sanction, while Infobae described the bilateral relationship as in an "unprecedented crisis, noting business concerns. Brazil is Argentina's main trading partner, absorbing 12.6% of Argentina's goods exports from January to June, ahead of China (9.9%) and the U.S. (9.8%), per Argentina's Indec statistics agency. In 2025, Argentina was the third-largest destination for Brazilian exports, totaling US$18.1 billion, or 5.2% of Brazil's total exports, according to Comex Stat data from Brazil's Ministry of Development, Industry, and Commerce (MDIC).
