Brazil downgraded its diplomatic relationship with Argentina on Tuesday, marking an unprecedented rupture between South America's two largest economies after Argentine President Javier Milei repeatedly called Brazilian President Luiz Inácio Lula da Silva "a thief." The move represents the first time in recent history that Brazil has taken such action against its neighbor.
A spokesperson for Brazil's foreign office confirmed Milei has attacked Lula three times since Sunday alone. The Argentine leader used similar language on July 25 at a party convention for Sen. Flávio Bolsonaro, son of former President Jair Bolsonaro, who will challenge Lula in October's election. Milei also called Brazilian Supreme Court Justice Alexandre de Moraes "trash" during the same event.
Diplomatic Fallout
Brazil recalled its ambassador to Buenos Aires, Julio Bitelli, in July following Milei's initial remarks against Lula. Since then, Brazil's interests in Argentina have been handled by a chargé d'affaires, a lower-ranked diplomatic position. Bitelli won't return to Argentina as long as Milei continues his aggressive commentary toward Lula, the spokesperson said.
The Brazilian president hasn't responded to Milei's attacks. The two leaders have maintained a frosty relationship since Milei took office in December 2023. Milei's close alliance with U.S. President Donald Trump, whose administration is at odds with Lula, has further strained regional relations.
Broader Regional Tensions
The diplomatic downgrade comes amid escalating international tensions involving Brazil. Earlier Tuesday, the U.S. State Department revoked the visa of Brazil's ambassador to Washington in retaliation for Brazil's denial of visas last month for two American diplomats who sought to visit ahead of upcoming elections.
De Moraes denied a request by Milei to visit Bolsonaro, who is under house arrest serving a 27-year sentence for a coup attempt. The denial added another layer to the deteriorating relationship between the two administrations.
Election Year Politics
Lula was officially declared candidate for reelection Sunday at his Workers' Party convention, where many voiced concerns of foreign interference in the country's vote. Vice President Geraldo Alckmin, a conservative who will once again be Lula's running mate, said the country's electronic voting system was so effective that "it doesn't accept any votes from Argentines and Americans," in a reference to Milei and Trump.
The timing of Brazil's diplomatic downgrade, just days after Lula's official candidacy announcement, underscores the intersection of domestic politics and international relations. Milei's continued attacks on Lula have forced Brazil to choose between maintaining normal diplomatic protocols and defending its head of state during an election year.
Why This Matters:
The breakdown in diplomatic relations between South America's two largest economies threatens regional stability and economic cooperation at a critical moment. Brazil and Argentina have deep trade ties and shared interests in regional security and commerce. Allowing personal animosity between leaders to disrupt institutional relationships sets a dangerous precedent for bilateral relations. The involvement of external actors—particularly the alignment between Milei and Trump against Lula—introduces foreign influence into what should be sovereign decision-making. For businesses operating across borders and markets dependent on regional stability, the diplomatic rupture creates uncertainty. The fact that Brazil felt compelled to take this unprecedented step suggests traditional diplomatic channels have failed, raising questions about whether institutional norms can withstand the pressures of populist politics and international polarization.
