Brazil under pressure: five geopolitical fronts reshaping South America

US tariffs, the dispute over Brazil's elections, the securitisation of organised crime, the crisis with Argentina and the rapprochement with China are not unrelated events. Taken together, they reveal a growing struggle to determine Brazil's international orientation and, by extension, the South American balance of power.

Why it matters

Brazil is Argentina's main trading partner and the country with which it shares the River Plate Basin, the Paraná-Paraguay waterway and the automotive, energy and nuclear chains. Whatever conditions Brazilian decisions conditions, one step later, Argentina's room for manoeuvre.

The agenda of the Brazilian media in recent days has been dominated by five events of a different nature, linked by the same strategic question, which is who will have the capacity to condition Brazil's sovereign decisions.

Trade pressure, electoral challenges, security redefinitions, the intervention of foreign leaders in the Brazilian campaign and Chinese offers of strategic cooperation are piling up on a country approaching a decisive presidential election.

What is under discussion is not only who will govern Brazil. Its international orientation, the degree of autonomy of its foreign policy, control over its strategic resources and the position it will hold in the competition between the United States and China are all in dispute.

1. US trade coercion

The first front is economic.

The Donald Trump administration imposed an additional 25% tariff on a considerable share of Brazilian exports. It later added a further 12.5% surcharge, based on alleged Brazilian shortcomings in preventing the entry of goods made with forced labour.

Although exemptions reduce the aggregate impact, some exports may face cumulative charges of up to 37.5%. The affected sectors include manufactures, footwear, clothing, chemicals, industrial goods and other segments sensitive for Brazil's productive capacity.

The conflict goes well beyond a tariff dispute. During the negotiations, Washington reportedly asked Brazil to remove tariffs unilaterally on certain US industrial, chemical, automotive and aerospace goods. Brazil considered some of those concessions legally incompatible with its trade policy and strategically unacceptable.

The Brazilian government announced that it would go to the World Trade Organization and is considering applying the Economic Reciprocity Law. Among the responses under study are measures on intellectual property, audiovisual royalties, pharmaceutical patents and sectors particularly sensitive for US companies.

From a geopolitical perspective, the United States is using its market as an instrument of pressure. The objective no longer seems limited to correcting a trade imbalance. It seeks changes in regulatory, digital and industrial areas that belong to the decision-making core of the Brazilian State.

The case of the Pix payment system is especially significant. Its inclusion among the practices challenged by Washington shows that national financial infrastructures have become objects of strategic competition. An efficient public platform can reduce the intermediation of foreign private companies and, for that reason, acquire a geopolitical dimension.

The central question for Brazil is whether it will preserve its national development instruments or accept conditions on its economic policy in exchange for preferential access to the US market.

2. Electoral sovereignty as a new field of dispute

The second front is unfolding within the Brazilian political system.

Brazil refused visas to two US State Department officials who intended to travel to the country and hold meetings related to the electoral process. The Superior Electoral Court confirmed that the US embassy had requested a meeting, although it had not formally communicated the content of the agenda. Washington denied that the mission was intended to interfere in the elections.

According to Brazilian officials quoted by the local media, the delegation sought to discuss electoral integrity, freedom of expression and the functioning of electronic voting machines. For Brasília, the attempt could reinforce a campaign aimed at casting doubt on the legitimacy of the voting system ahead of the presidential election.

The seriousness of the episode does not depend on proving in advance a foreign electoral operation. The problem lies in the fact that officials of an external power sought to intervene in a controversy that is part of Brazil's domestic political contest.

Election observation missions are legitimate when they act within institutional agreements, pre-established rules and multilateral mechanisms. They are more problematic when a power selects its interlocutors, raises unilateral objections or draws close to one of the competing forces.

Brazil has already invited organisations such as the OAS, the European Union, Parlasur, the Carter Center and international networks of electoral bodies. The contrast between regulated multilateral observation and a bilateral political mission is the core of the controversy.

Electoral sovereignty has thus become a specific dimension of national sovereignty. In the twenty-first century, foreign intervention does not need to take the classic form of a coup. It can operate through reputational challenges, selective sanctions, digital platforms, delegitimisation campaigns and early or conditional recognition of results.

3. From organised crime to «terrorism»: the risk of an expansive jurisdiction

The third front directly affects Brazil's control over its territory.

The United States designated the Primeiro Comando da Capital and the Comando Vermelho as foreign terrorist organisations. The Brazilian government rejected the equation of organised crime with terrorism, arguing that the two phenomena have different motivations, structures and legal treatment.

Foreign minister Mauro Vieira warned that the US designation could have financial, migration and criminal consequences for Brazilian citizens and companies. He also warned that the designation could become a pretext against Brazilian sovereignty.

This is not a matter of playing down the threat of drug trafficking. Brazilian criminal organisations control territories, financial networks, international routes, ports and border connections. They are a real threat to state authority.

But the way the problem is classified is not neutral.

When a foreign power labels as «terrorist» an organisation that operates within another state, it expands its capacity to apply sanctions, pursue assets, impose obligations on financial institutions and justify extraterritorial action. Police cooperation can gradually turn into a claim of external jurisdiction.

The Brazilian government maintains that the fight against organised crime must be deepened through intelligence sharing, the pursuit of money laundering, asset recovery, arms control and coordinated police operations. What it rejects is that Washington should determine unilaterally the legal nature of the problem and the consequences applicable within Brazil.

This debate is crucial for the whole of South America. If the doctrine of «narco-terrorism» becomes normalised, the United States could considerably widen its margin for regional intervention, especially in countries with transnational criminal organisations, strategic resources or weakened institutions.

4. The crisis with Argentina and the spread of the Brazilian dispute into Mercosur

The fourth front is particularly relevant for Argentina.

President Javier Milei took part in Brazil in the convention that formalised Flávio Bolsonaro's presidential candidacy. During that event he attacked President Luiz Inácio Lula da Silva and Supreme Federal Court justice Alexandre de Moraes.

The Brazilian government responded by recalling its ambassador in Buenos Aires for consultations and summoning the Argentine representative in Brasília. Brazilian diplomacy stated that Milei's remarks had gone beyond the tolerable limits of political confrontation between governments.

Recalling an ambassador does not amount to breaking off relations, but it is one of the most severe gestures available short of formally downgrading the diplomatic relationship.

The underlying issue is not the insults but the Argentine president's participation in Brazil's electoral contest.

When a head of state travels to another country's territory to support an opposition candidate, attack the sitting president and challenge members of its judiciary, he ceases to act solely as an ideological leader. His statements acquire the institutional weight of the State he represents.

The crisis affects the core of the South American system. Brazil and Argentina recorded trade of close to US$32 billion in 2025. In addition, the automotive, energy, industrial, nuclear, military and agri-food chains of both countries show varying degrees of interdependence.

The most serious consequence would be for Brazil to stop regarding Argentina as a stable strategic partner and begin to perceive it as a platform for the penetration of external interests or for ideological confrontation against the Brazilian State.

For Argentina, that perception would be enormously harmful. Brazil has greater territorial, demographic, industrial and diplomatic scale. It can partly diversify its alliances and markets. Argentina, by contrast, cannot easily replace the Brazilian relationship without paying considerably higher economic and strategic costs.

5. China offers backing, but also intensifies the competition for Brazil

The fifth front is China's response.

In a conversation lasting more than an hour, Lula and Xi Jinping agreed to accelerate talks on a possible agreement between China and Mercosur. They also discussed cooperation in artificial intelligence, satellites, energy, fertilisers, critical minerals and the industrial processing of resources.

Xi said that China supported Brazil in defending its sovereignty and independence against «external interference». The statement came amid US pressure and the crisis caused by Milei's participation in the Brazilian campaign.

Beijing seeks to present itself as a partner that respects Brazilian autonomy. But its interest is not disinterested.

Brazil has food, hydrocarbons, critical minerals, industrial capacity, space infrastructure, diplomatic weight and a strategic position on the South Atlantic. It is also the only Latin American state that combines continental scale, a relevant industrial base, partial technological autonomy and the capacity to lead coalitions of the Global South.

For China, consolidating the relationship with Brazil means securing resources, markets, influence within the BRICS and a presence in the leading South American power. For the United States, preventing a deep strategic integration between Brazil and China is a priority hemispheric question.

Brazil is no longer a passive periphery

The five stories examined show that Brazil can no longer behave as a passive periphery.

Its market, its minerals, its elections, its digital systems, its financial networks, its industry and its territorial position have been drawn into the competition between great powers. US pressure and the Chinese offer are different expressions of the same recognition, namely that Brazil has a scale that alters the hemispheric balance. Brazil's main difficulty will be to turn that potential importance into effective power.

To achieve this it will need to preserve social peace and territorial cohesion, strengthen its defence, control its critical infrastructure, develop its own technology, guarantee the legitimacy of the electoral system and prevent internal polarisation from allowing foreign actors to intervene in the country's strategic orientation.

The warning for Argentina

Argentina must observe the process without ideological blinkers.

A weakened, subordinated or internally divided Brazil does not necessarily benefit our country. It could turn South America into a space more permeable to extra-regional intervention and reduce the joint capacity to negotiate on trade, energy, defence, food, infrastructure and the South Atlantic.

But a stronger Brazil without an equivalent Argentine strategy could also widen the bilateral asymmetry and consolidate a regional division of labour unfavourable to our industrialisation.

The Argentine interest calls for a policy aimed at preserving the structural relationship with Brazil, avoiding any interference in its internal processes and rebuilding national capabilities that make it possible to negotiate from a more balanced position.

The competition between the United States and China is already reshaping South America. Brazil is its main piece. Argentina must decide whether it will take part in that reordering as a state with its own strategy or as disputed territory.
