The trip opens a parliamentary channel to Brasília while official Argentina Brazil relations stay frozen.
A cross-party group of Argentine deputies and senators travels to Brasília from 1 September 2026. They aim to reopen Argentina Brazil relations that Javier Milei’s insults to Lula da Silva froze.
A parliamentary mission to Brasília
A cross-party group of Argentine deputies and senators flies to Brasília next week. The mission runs from Tuesday 1 September to Thursday 3 September 2026.
The central day is Wednesday 2 September, when most of the meetings are booked. Organisers describe the trip as a parallel channel rather than a replacement for official diplomacy.
The delegation is due to meet the Foreign Relations Committee of Brazil’s Senate. Senator Nelsinho Trad chairs that committee and is a government ally from outside Lula’s party.
Talks are also planned at the Itamaraty Palace and the Planalto Palace. Itamaraty houses Brazil’s foreign ministry, while the Planalto is the seat of the presidency.
Who is travelling and which blocs they speak for
Nicolás Massot of the Encuentro Federal bloc is organising the trip. He told Infobae that the group represents parties holding 60 percent of Argentina’s parliamentary benches.
Confirmed travellers include Maximiliano Ferraro of the Coalición Cívica and Esteban Paulón of the Socialist Party. Senator Martín Lousteau of the Unión Cívica Radical is also on the list.
Oscar Herrera Ahuad of Innovación Federal and deputy Eduardo Falcón complete the confirmed group. Cecilia Moreau and Germán Martínez, both from the Peronist benches, are expected to join.
Massot said the aim is to show Brazil that a parliamentary majority rejects what happened. He also wants an institutional route that survives the current freeze in Argentina Brazil relations.
The mission grew out of a declaration Massot filed in the Chamber of Deputies. The governing bloc blocked that text, which had asked Foreign Minister Pablo Quirno to brief Congress.
How Argentina Brazil relations broke down
Milei travelled to São Paulo in late July for the Liberal Party convention. It formalised Flávio Bolsonaro’s presidential candidacy, and Milei called Lula a convict from the stage.
In early August he went further in Argentine interviews, calling Lula a thief and corrupt. The Rio Times covered those remarks and the first Brazilian reaction at the time.
Brazil first recalled ambassador Julio Bitelli from Buenos Aires for consultations. On 4 August it downgraded the link to chargé d’affaires level and kept Bitelli at home.
A minister-counsellor, Eduardo Uziel, now runs the Brazilian embassy in Buenos Aires. Argentina’s ambassador in Brasília, Daniel Raimondi, returned home, and Argentina Brazil relations have not moved since.
The trade numbers behind the alarm
Brazil remains Argentina’s largest trading partner despite the political rupture. The National Institute of Statistics and Censuses (INDEC) sets out the first-half picture in stark terms.
Argentine exports to Brazil reached US$6.25 billion between January and June 2026. Imports from Brazil came to US$7.65 billion over the same six months.
That gave Brazil 13 percent of Argentine exports and 22 percent of imports. One in every eight export dollars earned in the half came from the Brazilian market.
Full-year 2025 shares were higher, at 14.7 percent of exports and 24.3 percent of imports. Argentina ran a US$5.65 billion goods deficit with Brazil that year.
Brazilian data tell the same story from the other side of the border. Two-way trade ran near US$31 billion in 2025, according to Brazil’s trade and investment promotion agency, ApexBrasil.
Mercosur and the European Union deal
Mercosur, the Southern Common Market, is the customs union that binds the two economies. Argentina, Brazil, Paraguay and Uruguay founded it, and Bolivia later joined as a full member.
The bloc signed a partnership agreement with the European Union in Paraguay on 17 January 2026. The European Council had cleared the signature eight days earlier.
An interim trade agreement has applied provisionally since 1 May 2026. Tariffs on some product lines fell from the first day of that provisional period.
The full pact still needs consent from the European Parliament and ratification by every member state. Those steps ask Mercosur governments to hold a common line for years.
Argentina and Brazil are the two largest members and set the bloc’s tone. A frozen channel between them complicates any joint position in Brussels.
Why carmakers watch the flex rule
Cars and parts move under Economic Complementation Agreement 14, in force since December 1990. The deal manages bilateral vehicle trade rather than freeing it.
Its flex rule sets how far the two flows may diverge. Between July 2025 and June 2027 Brazil may ship two dollars of vehicles for each Argentine dollar.
The cap is due to disappear in June 2029, opening full free trade in vehicles. A 35 percent common external tariff shields both markets from outside producers.
Massot argues the Argentine car industry depends heavily on that agreement. Transport equipment made up 18 percent of Argentine imports in the first half of 2026.
Carmakers have publicly asked for the regime to be extended beyond 2029. Neither government has opened that negotiation while the diplomatic channel stays frozen.
Energy links and the limits of parliamentary diplomacy
Gas is the newer thread in the relationship. Argentine gas from Vaca Muerta began reaching Brazil through reversed Bolivian pipelines in 2025.
Transportadora de Gas del Norte is pushing a new line from Tratayén to La Carlota. Its first phase carries an estimated cost near US$2 billion.
Brazilian demand is projected at about 101 million cubic metres a day by 2035. That is roughly 48 percent above current levels.
Massot recalls that a Petrobras vessel supplied Argentina during a 2024 energy emergency. Brazil also represented Argentine interests in Venezuela after Buenos Aires lost its mission there.
He concedes that parliament cannot replace official diplomacy in a strongly presidential system. Argentina votes again next year, and he wants the gap filled until then.
