Brazil’s foreign policy stands out in this comparison for its visible effort to shape global forums and press for changes to multilateral governance. Its 2024 G20 agenda and 2025 BRICS presidency linked that ambition to development and economic cooperation. Mexico’s 2020–2024 program, Colombia’s 2024 retrospective and Chile’s 2022–2026 policy account emphasize different priorities and instruments; Argentina’s declined BRICS invitation marks a specific contrast with Brazil. These records show what governments said or reported doing, not a ranking of influence or proof of policy success.
How do the five countries’ documented approaches compare?
The evidence spans different periods and document types, so the table compares stated priorities and reported diplomatic activity—not equivalent measures of results. Argentina is represented only by its decision on a BRICS invitation.
| Country | Evidence and period | Distinctive emphasis in this record |
|---|---|---|
| Brazil | Statements tied to its 2024 G20 presidency and 2025 BRICS presidency | Using high-profile global forums to promote multilateral governance reform and development, alongside economic cooperation. |
| Mexico | Foreign-affairs program for 2020–2024 | Multilateral diplomacy framed around sustainable development, migration, rights, peace, gender equality and social justice, with a regional focus on dialogue and integration. |
| Colombia | Foreign ministry retrospective of 2024 activities | Practical cooperation through regional institutions, including work on energy, security, the environment, social policy and trade. |
| Chile | Foreign-policy report covering 2022–2026, described in the available official search-result material | Adherence to international law and defense of multilateralism; the available account supports only this narrow description. |
| Argentina | Official BRICS FAQ on the 2023 invitation | Declined an invitation to join BRICS from January 2024, unlike Brazil, which held the bloc’s presidency in 2025. |
What is Brazil trying to do through the G20 and BRICS?
The G20: development and governance reform
At the G20 Foreign Ministers Meeting on February 21, 2024, Brazil’s Foreign Minister Mauro Vieira described three priorities for Brazil’s presidency: fighting hunger, poverty and inequality; pursuing sustainable development across economic, social and environmental dimensions; and reforming global governance institutions. The agenda therefore joined domestic-facing development concerns to a call for changes in international institutions.
BRICS: reform paired with economic cooperation
Brazil’s 2025 BRICS presidency organized its stated priorities across political and security, economic and financial, and cultural and people-to-people cooperation. Politically, it emphasized multilateralism, improved global governance, reform of the UN Security Council, conflict prevention and cooperation against terrorism and corruption. Economically, it included intra-BRICS trade and investment, local-currency use, international payment platforms, government procurement cooperation, trade facilitation and sustainable finance for energy and climate transitions.

In a statement read at the BRICS Peace and Security, Global Governance session in Rio de Janeiro on June 6, 2025, President Luiz Inácio Lula da Silva said: “With multilateralism under attack, our autonomy is once again in check.” At the BRICS foreign ministers’ meeting in April 2025, Vieira put the diplomatic method this way: “We defend diplomacy instead of conflict, and cooperation instead of unilateralism.” Both remarks express the government’s position in specific forum settings; they are not independent assessments of Brazil’s influence.
How do Mexico, Colombia, Chile and Argentina differ?
Mexico: a program centered on inclusion and regional dialogue
Mexico’s 2020–2024 foreign-affairs program treated multilateral engagement as a means to advance sustainable development, peace, migration and human rights, non-discrimination and gender equality, global economic issues, innovation and social justice. For Latin America and the Caribbean, it called for continued high-level dialogue, partnerships including with Argentina, Chile and Colombia, consolidation of the Pacific Alliance, and active participation in regional and subregional mechanisms.
The program also situates Mexico in a North American context: it identifies relations with the United States and Canada as highly consequential to the country’s economic and political circumstances. Its regional priorities should therefore not be read as evidence that Mexico occupies the same geopolitical position as Brazil in South America. The document’s stated agenda covers 2020–2024 and should not be treated as a complete account of Mexico’s policy in 2026.
Colombia: regional cooperation described through activities
Colombia’s foreign ministry account of 2024 describes initiatives across several regional bodies. Under the Brasilia Consensus, it reports work on energy interconnection and gas integration, energy planning, infrastructure and transport, security institutions, environmental crime, education and regional risk management. In the Andean Community, the account lists social policy, biodiversity and climate, peace and security, institutional strengthening, digital development, sustainable employment and productive capacity. It also describes Colombia’s work in the Pacific Alliance, CELAC and other forums.
The retrospective says Colombia was chosen to assume CELAC’s pro tempore presidency in March 2025 and notes a 2025 focus in the Pacific Alliance. Those are time-bound institutional roles, not evidence by themselves of outcomes. The ministry also reports a contribution of USD 180,000 to a Project Mesoamerica public-policy exchange initiative; that figure describes the specific contribution, not a general measure of Colombian diplomatic spending or influence.
Chile: a narrow, law-centered comparison
The official account available for Chile’s 2022–2026 foreign-policy report describes adherence to international law and defense of multilateralism. It also notes President Gabriel Boric’s engagement with Brazil: Luiz Inácio Lula da Silva visited Chile in August 2024, and Boric made a state visit to Brazil in April 2025. The available material does not establish a fuller set of Chilean policy priorities, so broader comparisons would go beyond what it supports.
Rank #4
Argentina: a specific BRICS decision, not a full foreign-policy profile
An official BRICS FAQ records that Argentina was invited at the 2023 Johannesburg summit to join from January 2024 and declined. This distinguishes Argentina’s recorded choice from Brazil’s subsequent BRICS presidency, but it does not establish Argentina’s wider diplomatic alignment, the reasons for the decision or its current positions across other issues.

The clearest contrast is in the diplomatic instruments represented here. Brazil’s evidence centers on summit agendas and leadership of global forums; Colombia’s is a retrospective of work through regional institutions; Mexico’s is a forward-looking program for a defined four-year period; Chile’s evidence is narrower; and Argentina’s covers one membership decision. Those differences matter: a presidential statement, a program and a ministry’s activity report do not measure the same thing.

The documents establish official priorities and reported activity, not consistent implementation or policy impact. No common, comparable measure of influence or success across all five countries is established by these records. The defensible comparison is qualitative: Brazil’s cited agenda is especially explicit about reshaping global governance through the G20 and BRICS, while the other available records foreground different regional, social, legal or institutional dimensions.
