Brazil recalled its ambassador to Argentina on Sunday after President Javier Milei traveled to São Paulo and publicly called Brazilian President Luiz Inácio Lula da Silva a "thief" and a "delinquent," escalating a diplomatic crisis that threatens economic ties between South America's two largest economies.
The extraordinary move came one day after Milei appeared at an event where Brazilian Sen. Flávio Bolsonaro, son of former President Jair Bolsonaro, was confirmed as his father's party's presidential candidate. During his Saturday speech, Milei also called Supreme Federal Court Minister Alexandre de Moraes "trash" after de Moraes denied him a visit to Jair Bolsonaro, who's under house arrest serving a 27-year sentence over a coup attempt.
Insults on Brazilian Soil
The president of Brazil's Supreme Federal Court, Minister Edson Fachin, condemned what he called a "disrespectful reference to a magistrate of the highest court in the country, made on Brazilian soil." A spokesperson for Brazil's foreign affairs ministry confirmed that Ambassador Julio Bitelli was recalled for consultations following Milei's statements.
Former Argentine President Alberto Fernández posted a video on X on Sunday exposing Milei's insults. "Milei went to Brazil shouting like a madman, demanding to see a coup plotter in jail," Fernández wrote. He added, "Insulting the president of a sister nation and our main trading partner is unforgivable."
Argentine Leaders Distance Themselves
Axel Kicillof, the governor of the province of Buenos Aires and a potential candidate in next year's general elections, said on X that he contacted Brazilian Foreign Minister Mauro Vieira on Sunday "to convey that Milei does not represent the feelings of the Argentine people." Kicillof said he watched "with profound shame as President Milei offended and insulted the Brazilian government, its president, and the entire country."
"From the province of Buenos Aires, we maintain that Argentina respects its sister nations and is committed to regional integration," Kicillof said. He emphasized that Brazil is Argentina's main trading partner and warned that "with these provocations, Milei is jeopardizing investments, exports, thousands of jobs, and Argentina's interests, all to support a candidate at Trump's behest."
Broader Regional Tensions
Lula hasn't publicly addressed Milei's remarks. But in an opinion piece published Sunday by The Washington Post, he called U.S. tariffs against Brazil "a strategic mistake" and wrote that "Brazil's destiny is determined only by Brazilians without external interference, without subservience." Those comments came a day after Brazil's Foreign Ministry denied visas to two U.S. State Department officials who sought to travel to the South American nation next week. The ministry didn't offer an explanation.
Lula is seeking reelection and will run against Sen. Flávio Bolsonaro, whose family has many ties with the Trump administration.
Why This Matters:
Milei's diplomatic breach threatens economic stability for workers and businesses across both nations at a time when regional cooperation matters most. Brazil and Argentina form the backbone of Mercosur, and their trade relationship supports thousands of jobs on both sides of the border. When a president uses inflammatory rhetoric to support a foreign political candidate—particularly one whose father attempted a coup—he undermines democratic institutions and the multilateral frameworks that protect smaller economies from great-power interference. Kicillof's warning about jeopardized investments and exports isn't hyperbole. It's a recognition that ordinary Argentines will bear the cost of their president's recklessness. The recall of Brazil's ambassador signals that South America's largest democracy won't tolerate attacks on its judicial independence or its sovereign right to hold coup plotters accountable, regardless of their international connections.
