The Mercosur-European Union Agreement and Brazil’s new phase in the Global South Market
By Ronaldo Vieira
The Mercosur–European Union Agreement is widely recognised as a trade and cooperation treaty that establishes the largest free trade area ever negotiated by Brazil within the Mercosur framework. It links the vast European consumer market to the economies of the South American bloc. After nearly two decades of negotiation, the agreement will enter into force provisionally and gradually in 2026, once the ratification procedures required by both blocs are completed. From that moment on, tariffs will begin to fall, and new regulatory rules will take effect. The central objective is to expand trade, facilitate investment, harmonise technical standards, and strengthen production chains, creating a more predictable and competitive environment for companies on both sides.

The treaty is the largest inter-bloc agreement in the Western world and represents a historic milestone capable of reshaping relations between emerging economies and industrial powers. Yet it arrives in an international landscape very different from the one in which it was conceived 20 years later. In this new context, it places Mercosur at the centre of debates on the need to revitalise multilateralism. It highlights the Global South as a strategic actor amid intensifying geopolitical competition, where instability has become part of the commercial game. Countries of the Global South are seeking greater agency, and China occupies a central position in this rearrangement.
Although the agreement is gaining renewed appeal at this moment, being described as historic for multilateralism and as a gesture of confidence in international trade as a driver of economic growth, it is legitimate to question whether it can truly address all the challenges faced by Mercosur or whether its benefits will be unevenly distributed. The question is unavoidable: will the agreement genuinely support the traditionally weaker side of the relationship, or could it deepen existing asymmetries?
Answering these questions is essential for understanding Brazil’s strategic role in global trade and for shaping policies that ensure the agreement becomes a vector for sustainable development rather than another chapter in the long history of international commercial imbalances.
While the Mercosur-EU Agreement represents a historic opportunity for economic, technological, and regulatory integration, its ability to strategically reposition Mercosur countries and strengthen the Global South depends less on the treaty’s text and more on the strategies adopted by developing nations themselves. The warning is clear: the agreement does not automatically reduce asymmetries. It may even widen them if the Global South fails to organise itself to fully seize advantages such as preferential access to the European market, productive modernisation, and investment attraction.
Coordinated industrial policies, regional integration, stronger value chains, and regulatory harmonisation can transform the agreement into an instrument of sustainable development. These elements can help historically marginalised countries move into more advantageous positions in global trade. In other words, the agreement is not inherently beneficial to the weaker side, but it can become a powerful lever if the Global South acts in a coordinated strategic manner focused on generating added value.
Initially, it is understandable that many Brazilian companies tend to view the agreement simply as an opportunity for direct business with Europe, focusing on market access, tariff reductions and export expansion. Although accurate, this perspective is limited and captures only part of the treaty’s transformative potential. Brazil occupies a unique position to serve as a bridge between the Global South and the European market within the framework of the agreement. Its ability to move with legitimacy across Latin America, Africa, and Europe gives the country a strategic role in shaping economic, technological, and cultural flows that transcend regional boundaries.
The agreement offers Brazil direct advantages that strengthen its competitiveness and expand its international reach. Tariff reductions for thousands of products, access to a market of more than 450 million consumers, and integration into European production chains reinforce sectors such as agribusiness, manufacturing, energy, technology, and the creative economy.
The country is also likely to attract European investment in infrastructure, innovation, and energy transition, which can modernise industry and generate added value. The agreement gains relevance by promoting renewable technologies and unlocking investment in critical minerals, reinforcing Brazil’s role as a leader in the global energy transition. With one of the cleanest energy matrices in the world and vast reserves of strategic minerals and rare earths, the country has a unique opportunity to connect Mercosur to the global decarbonisation agenda.
Regulatory predictability and the possibility of participating in European public procurement create a favourable environment for Brazilian companies to expand internationally sustainably and competitively. The same applies to European companies in Brazilian tenders under equivalent conditions. To mitigate historical inequalities, the agreement includes mechanisms to balance market opening with the preservation of national technological sovereignty, including offset clauses requiring technology transfer or local production.
By assuming this bridging role, Brazil can extend the agreement’s benefits to other countries in the Global South, including Nigeria. Regional productive integration allows inputs, components, and services from African and Latin American countries to be incorporated into Brazilian industrial chains destined for the European market. European investment attracted to Brazil can also generate trilateral projects with Global South partners in renewable energy, logistics, sustainable agriculture, and digitalisation. Regulatory harmonisation led by Brazil can help third countries meet European standards, reducing technical barriers and increasing regional competitiveness.
It is also important to recognise that the Mercosur–EU Agreement is only one of several instruments shaping relations between Europe and the Global South. It coexists with intracommonwealth agreements, bilateral treaties between African, Asian, and Latin American countries and European states, and multilateral mechanisms for trade and investment facilitation. In this complex environment, the Global South cannot act in a fragmented manner. It must organise itself strategically to operate within this ecosystem of agreements, harmonise regulatory standards, strengthen regional production chains, and expand its negotiating capacity.
Coordinated participation by the Global South is essential for these instruments, including the Mercosur–EU Agreement, to move beyond formal opportunities and become real tools for sustainable development capable of generating added value, technological innovation, productive inclusion, and greater international presence for developing countries.
By articulating these dimensions, Brazil helps the Global South participate more effectively and more strategically in international trade. Here is where the opportunities for Nigerian companies lie. The country transforms its role in the agreement into a platform for cooperation, development, and innovation, expanding the collective presence of the Global South in the European market. In this process, the agreement ceases to be merely a commercial instrument and becomes a catalyst for regional transformation. The Global South emerges as a central stakeholder between hemispheres, repositioning itself on the global stage with greater strength, greater voice, and greater ambition.
