A Handshake Across a Quarter-Century: The EU-Mercosur Free Trade Agreement Reshapes the Global Trade Landscape.

On January 17, 2026, in Asunción, the capital of Paraguay, the Grand Theater was brilliantly illuminated. A ceremony awaited for over a quarter of a century was taking place. European Commission President Ursula von der Leyen and Santiago Peña, President of Paraguay, the rotating presidency of Mercosur, exchanged documents, formally signing the free trade agreement between the European Union and Mercosur. At this moment, the world's largest free trade area was officially born—an economic space spanning both sides of the Atlantic, covering 720 million consumers with a combined GDP exceeding 22 trillion US dollars.

From the initiation of negotiations in 1999 to the final signing in 2026, this agreement has traversed a 26-year journey of twists and turns. It was born in an era rife with contradictions: rising global protectionist sentiments, deepening geopolitical rifts, and unprecedented pressure on the multilateral trading system. Yet, it is precisely against this backdrop that two regional blocs, with deep historical ties and shared democratic values, chose a distinctly different path—not by erecting higher barriers, but by dismantling the tariff walls that once stood across the Atlantic.

A marathon negotiation spanning generations.

In June 1999, in Rio de Janeiro, Brazil, leaders from the European Union and Mercosur officially launched free trade negotiations for the first time. The world back then was vastly different from today: China had just joined the World Trade Organization, the United States was pushing for the establishment of the Free Trade Area of the Americas, and European integration seemed unstoppable. No one could have anticipated that these negotiations would become one of the longest marathons in the history of international trade.

The core contradiction of the negotiations was clear from the very beginning. Mercosur hoped to open the door to the European market for its most competitive agricultural products—particularly beef, soybeans, and sugar. Meanwhile, the EU targeted Mercosur's highly protected industrial sectors, especially the automotive manufacturing industry, which at the time faced tariff barriers as high as 35% in Mercosur countries.

Former Uruguayan Deputy Foreign Minister Valeria Chukasi, who led the Mercosur negotiation team from 2016 to 2019, recalled: The ups and downs of the negotiations were always closely linked to the influence of the United States. At the beginning, the EU was concerned that the U.S. would gain an advantage in Latin America through the Free Trade Area of the Americas plan; at the end, it was Trump's trade protectionist policies that prompted Europe to accelerate its search for new market partners.

History indeed exhibits a remarkable symmetry. In 2005, at the Summit of the Americas held in Mar del Plata, Argentina, former Venezuelan President Chávez loudly called for the burial of the Free Trade Area of the Americas, and the collective opposition from left-wing governments in Latin America caused the plan to be stillborn. Almost simultaneously, negotiations between the European Union and the Southern Common Market also stalled—once the competitive pressure from the United States disappeared, Europe's sense of urgency regarding the South American market diminished accordingly.

The true turning point occurred in 2016. At that time, the Pink Tide in Latin America gradually receded, with the Temer administration in Brazil and the Macri administration in Argentina coming to power, shifting both countries' economic policies toward a more open direction. Simultaneously, Europe was experiencing the shock of the Brexit referendum, and after Donald Trump was elected President of the United States, he promoted an America First policy, leading to a deterioration in the global trade environment. The two major blocs suddenly realized that they needed each other to cope with an increasingly uncertain world.

The period from 2016 to 2019 became the most intensive phase of negotiations. Both sides exchanged formal lists of demands for the first time, but significant differences remained. The EU initially offered only a 60,000-ton duty-free quota for beef, while Mercosur's expectation was five times that amount. In response, Mercosur proposed a longer transition period for tariff reductions on automobiles. The talks reached a deadlock at one point, and a principled agreement was not reached until 2019.

However, the signing ceremony did not take place as scheduled. Environmental issues, agricultural protection, and geopolitical changes—a mix of old and new problems—caused the agreement to stall once again at the last moment. It was not until the end of 2025, after intense internal negotiations within the European Union, that a majority of the 27 member states finally agreed to sign.

Strategic Choices in the Geopolitical Chessboard

The EU-Mercosur Agreement is far more than just an economic document. In the context of intensified competition among major powers and the restructuring of global supply chains, this agreement carries profound geopolitical significance.

For the European Union, this agreement is a concrete practice of its strategic autonomy concept. Faced with the continuously increasing tariffs imposed by the Trump administration in the United States and China's growing influence in global trade, Europe urgently needs to diversify its economic partnerships. After the signing, EU Trade Commissioner Maroš Šefčovič stated: If anyone believes in high tariffs and power politics, then the Mercosur and European countries, representing over 700 million people, clearly demonstrate that we believe in international law, predictability, certainty, and the elimination of trade barriers.

The signing of the agreement coincided with Trump's announcement of imposing 10% tariffs on eight European countries, citing their opposition to U.S. control over Greenland. Although not explicitly named, von der Leyen's remarks at the signing ceremony clearly addressed this context: We have made a clear and deliberate choice: we choose fair trade over tariffs; we choose productive, long-term partnerships over isolation.

For the countries of the Southern Common Market, particularly the regional powers Brazil and Argentina, this agreement also holds strategic significance. On the eve of the agreement's signing, Brazilian President Luiz Inácio Lula da Silva wrote: In an era where unilateralism isolates markets and protectionism stifles global growth, two regions that share democratic values and are committed to multilateralism have chosen a different path. Although Lula did not attend the signing ceremony due to dissatisfaction with the additional demands raised by the European Union at the final stage, he remains a key promoter of the agreement.

The shift in stance by Argentine President Javier Milei is particularly striking. Known for his radical libertarian views, this leader once referred to the Southern Common Market as a prison and threatened to withdraw, yet ultimately became a staunch supporter of the agreement. At the signing ceremony, Milei stated: Argentina understands firsthand that closure and protectionism—sheltered by rhetoric rather than results—are the greatest causes of economic stagnation. Analysis indicates that Milei's change stems from his belief in free trade principles outweighing his skepticism toward the regional bloc itself.

The agreement also reflects the efforts of Global South countries to seek greater voice in the international trade system. Data from the Brazilian National Confederation of Industry is quite compelling: after the agreement takes effect, Brazil's share of global imports covered by preferential trade arrangements will jump from 8% to 36%. This means nearly one-third of Brazil's foreign trade will enjoy preferential treatment, significantly enhancing the country's strategic position in global supply chains.

Economic Complementarity and Structural Challenges

From an economic perspective, there exists a natural complementarity between the European Union and the Southern Common Market. Europe holds strong competitiveness in high-end manufacturing, chemicals, pharmaceuticals, machinery and equipment, and the automotive sector; South American countries, on the other hand, are globally significant suppliers of agricultural products, minerals, and energy. This complementarity creates substantial potential for trade creation between the two sides.

According to the agreement text, the EU will eliminate tariffs on 91% of imports from Mercosur, while Mercosur will implement zero tariffs on 92% of EU imports. Specifically, European automobiles, machinery, wine, spirits, and chemicals will gain easier access to the South American market; meanwhile, South American beef, soybeans, sugar, rice, and honey will secure a smoother entry into Europe.

The research from the National Confederation of Industry of Brazil provides a more detailed picture: 54.3% of Mercosur products will enjoy zero-tariff treatment with the European Union immediately after the agreement takes effect. In contrast, Brazil has set a tariff reduction transition period of 10 to 15 years for 44.1% of EU products, providing adjustment time for domestic industries. Ricardo Alban, President of the Brazilian Industrial Confederation, described the agreement as the most important commercial decision for Brazilian industry in decades.

However, the economic impact of the agreement is not without controversy. European farmers, particularly agricultural groups in countries such as France, Poland, and Austria, are concerned that cheap South American agricultural products could flood local markets. In recent weeks, French farmers have driven hundreds of tractors to block streets in Paris and dumped dozens of tons of potatoes in protest against the agreement. To address these concerns, the European Commission has included safeguard clauses in the final text, allowing temporary restoration of tariffs in the event of a surge in imports, and has pledged to strengthen inspections for pesticide residues in imported agricultural products.

President Graziano Messana of the Sao Paulo Chamber of Commerce stated in an interview with Italy's "Il Sole 24 Ore": There are two voices within France: multinational corporations and large enterprises supporting the agreement, and farmers protesting on the streets. In fact, two-thirds of the French people support this agreement. Messana predicts that the EU may ultimately offer compensation to French farmers in exchange for France not obstructing the approval of the agreement.

For the Mercosur countries, challenges also exist. The Brazilian Machinery and Equipment Industry Association warns that although the agreement will bring cheaper products to end consumers and benefit agribusiness, it poses risks to the domestic manufacturing sector. The association's executive president, José Velloso, stated: Brazil needs to address issues such as high taxes and high interest rates, and improve the business environment in order to fully utilize the opportunities brought by the agreement.

The Path to Approval: The Final Hurdle

The signing ceremony is just the first step. For the agreement to truly take effect, a series of legal and political obstacles still need to be overcome.

According to the EU legal process, the agreement is divided into two parts: the first part is the purely trade-oriented "Interim Trade Agreement," which only requires approval from the Council of the European Union and the European Parliament; the second part is the broader "EU-Mercosur Partnership Agreement," involving investment and political cooperation, which requires approval from the parliaments of each EU member state one by one. The latter may take several years.

The European Parliament has become the biggest variable at present. Despite the European Commission's plan to lobby Members of the European Parliament starting next week, hoping for approval in the first half of this year, opposition remains strong. At least 150 MEPs have threatened to submit the agreement to the European Court of Justice for legal review, a process that could delay it by 18 to 25 months.

France is the main opposing force. President Emmanuel Macron is concerned that farmers' discontent could drive more voters to support the far-right in the 2027 presidential election. Although the EU has secured additional subsidies for French farmers and successfully brought Italy into the supporting camp, France's position remains unchanged.

Officials from the European Commission revealed that, in theory, the Commission has the authority to provisionally apply the agreement after signing, but there are currently no plans to do so. For clarity: no decision has been made yet regarding the provisional application of the Mercosur agreement. One official stated that in the coming weeks, the Commission will focus on collaborating with members of the European Parliament to secure their support.

On the side of the Southern Common Market, the approval process is expected to be relatively smooth. Brazil, Argentina, Paraguay, and Uruguay need to approve the agreement through their respective legislative and administrative procedures. Given the supportive stance of the leaders of these countries toward the agreement, this process may be completed quickly.

Beyond Trade: The Symbolism of Multilateralism

At a deeper level, the EU-Mercosur Agreement represents a multilateral response to unilateralism and a counterattack by the rules-based global trading system against the wave of protectionism.

President Lula wrote in his signed article: No economy can exist in isolation. International trade is not a zero-sum game. All economies seek development, and this new partnership will create shared opportunities for employment, income generation, sustainable development, and economic progress. He emphasized that the agreement is beneficial not only for Brazil and the Southern Common Market, but also for Europe, and especially for the democratic world.

The agreement also incorporates provisions on the environment, labor rights, and sustainable development, reflecting the increasingly complex nature of contemporary trade agreements. Both parties commit to adhering to international standards on forest conservation, climate change, and workers' rights, aiming to strike a balance between promoting trade and protecting public interests.

Senior policy researcher at the European Council on Foreign Relations, Agathe Demarais, pointed out: The European Union's highest list of demands for developing economies willing to sign free trade agreements is often perceived as condescending. This perception gap has repeatedly caused tensions during negotiations, ultimately resolved through compromise.

From a broader historical perspective, this agreement may become a milestone in the process of regional economic integration. Since its establishment in 1991, Mercosur has experienced multiple internal crises, with significant disagreements among member states over trade policies. Uruguay and Argentina have previously sought to sign trade agreements separately with other countries, weakening the group's cohesion. As the largest trade agreement in the history of Mercosur, this deal with the European Union may revitalize the bloc and strengthen its internal unity.

The Global Trade Landscape in the New Paradigm

The establishment of the EU-Mercosur Free Trade Area is reshaping the global trade landscape. An economic space spanning the Atlantic and connecting two continents has thus been formed, with a scale second only to the Regional Comprehensive Economic Partnership Agreement in the Asia-Pacific region.

This change occurs during a critical period of global supply chain restructuring. As strategic competition between the U.S. and China intensifies, many countries are seeking to reduce dependence on a single market and achieve diversification of supply chains. The close ties between the European Union and the Southern Common Market provide new options for businesses on both sides. European companies can secure stable supplies of agricultural products and mineral resources, while South American enterprises gain access to European technology, investment, and high-end markets.

The President of the São Paulo Chamber of Commerce in Brazil, Mesana, summarized the significance of the agreement with a famous quote from the 19th-century French liberal economist Frédéric Bastiat: "If goods do not cross borders, armies will." In an era of rising risks of war and conflict, strengthening economic interdependence is a crucial means of maintaining peace.

The agreement may also have a demonstrative effect, promoting negotiations on other regional trade agreements. The European Union is currently engaged in trade negotiations with countries such as India and Australia, while Mercosur is also considering reaching agreements with economies like Singapore and South Korea. The final approval and implementation of the EU-Mercosur agreement will provide important references for these negotiations.

However, the ultimate success of the agreement depends on its implementation. Whether the commitments on paper can translate into tangible economic benefits will determine whether it is seen as a historic achievement or yet another empty declaration. The Brazilian Confederation of Industry warns that if Brazil does not address the "Brazil cost" issue—including structural obstacles such as insufficient infrastructure, a complex tax system, and cumbersome bureaucratic procedures—the theoretical advantages of the agreement may fail to materialize into practical gains.

A quarter-century of waiting has come to an end, but a new journey has just begun. The free trade experiment between the European Union and Mercosur will unfold against the backdrop of profound transformations in the global trading system. Its success or failure will not only affect the economic well-being of 720 million people but also provide a significant example for international cooperation in the 21st century. In an increasingly divided world, this agreement proves that rules-based multilateral cooperation remains a possible and necessary choice.
