Brazilian foreign policy

The diplomatic tradition

Brazil's foreign service is one of the oldest continuous professional diplomatic bureaucracies in the Americas. Its institutional memory reaches back to the Baron of Rio Branco (1845–1912), Foreign Minister from 1902 until his death, who settled the country's territorial questions largely through negotiation and arbitration — including the 1903 Treaty of Petrópolis over Acre. He is regarded as the patron of Brazilian diplomacy, and the Instituto Rio Branco, the diplomatic academy founded in 1945, bears his name.

Itamaraty takes its informal name from the palace in Rio de Janeiro that housed the ministry from 1899 until 1970, when it moved to Oscar Niemeyer's Palácio Itamaraty in Brasília, inaugurated on 21 April 1970. The continuity of a career service recruited by competitive examination is often cited as a source of the consistency of Brazilian diplomacy across changes of government.

Constitutional principles

Article 4 of the 1988 Constitution sets out the principles that govern Brazil's international relations. In the English translation published by the Constitute Project, they are:

1. I.national independence
2. II.prevalence of human rights
3. III.self-determination of peoples
4. IV.non-intervention
5. V.equality among States
6. VI.defense of peace
7. VII.peaceful solution of conflicts
8. VIII.repudiation of terrorism and racism
9. IX.cooperation among people for the progress of humanity
10. X.concession of political asylum

Its sole paragraph adds that Brazil "shall seek the economic, political, social and cultural integration of the people of Latin America, with a view toward forming a Latin-American community of nations."

Non-intervention and the defence of peace

Non-intervention and the peaceful settlement of disputes are constants of Brazilian diplomatic discourse. They explain, for example, Brazil's traditional preference for mediation and for UN-mandated action, and its reluctance to endorse unilateral sanctions or the use of force outside the Charter framework. In his March 2023 interview with Americas Quarterly, Mauro Vieira described Brazil as "a pacifist country" and called this its "diplomatic DNA".

Multilateralism

Brazil was a founding member of the United Nations in 1945 and has opened the general debate of every regular session of the UN General Assembly since 1955 — a protocol tradition rather than a formal rule. It has served eleven terms as an elected member of the Security Council, most recently in 2022–23, and has long campaigned for Council reform, including a permanent seat for itself.

Multilateralism, for Brazilian diplomacy, is both a principle and an instrument: it offers a middle-sized power influence it could not exercise alone. That logic underlies Brazil's role in the WTO, the G20 and climate negotiations.

South-South relations

Brazil's relations with Africa, Asia and the Middle East have deep historical roots — Brazil was the first country to recognise the independence of Angola, on 11 November 1975 — and a modern institutional form in the Brazilian Cooperation Agency (ABC), created in 1987, and in coalitions such as IBSA (2003) and BRICS (2009). See Brazil & the Global South.

Regional integration

The constitutional commitment to Latin American integration has been expressed through Mercosur (1991), UNASUR (2008) and CELAC (2011). Participation has varied with governments: Brazil withdrew from UNASUR in 2019 and suspended its participation in CELAC in 2020, then returned to both in 2023. See Regional Diplomacy.

Strategic partnerships

Brazil uses the category of "strategic partnership" to structure its most important bilateral relationships. Examples documented in this archive include China (1993, raised to a comprehensive strategic partnership in 2012), India (2006), France (2006), the European Union (2007), Germany (2008) and — most recently — the United Kingdom, with a Strategic Partnership for 2026–2030 signed by Mauro Vieira in March 2026.

Economic diplomacy

Trade promotion and negotiation are core Itamaraty functions, conducted alongside the trade and agriculture ministries. China has been Brazil's largest trading partner since 2009; Brazilian exports reached a record US$348.3 billion in 2025. See Economic & Commercial Diplomacy.

International law and the United Nations

Brazilian diplomacy consistently frames its positions in terms of the UN Charter and international law. Examples on the record include the call, at the G20 Foreign Ministers' Meeting in February 2024, for reform of the UN, WTO, World Bank and IMF, and Brazil's emphasis on international humanitarian law in statements on the Middle East.

Mauro Vieira's documented role

As a career diplomat, Vieira spent four decades executing the policies of successive governments before becoming minister. As minister he is the principal executor and public voice of the President's foreign policy. The record documents him chairing meetings (the Security Council in October 2023; G20 foreign ministers in 2024; BRICS foreign ministers in 2025), signing agreements (EU–Mercosur, January 2026; the UK–Brazil Strategic Partnership, March 2026), negotiating (with the United States on tariffs, 2025) and articulating positions in speeches and interviews.
