GEO-LAC: The EU–Mercosur Agreement Enters into Force

Event Series: GEO-LAC: Latin America in the New Geoeconomic Order

EU and Mercosur flags

After more than 25 years of negotiations, the EU–Mercosur Agreement is entering a decisive new phase. Its provisional application represents a historic milestone in the relationship between Europe and South America and opens a new chapter for trade, investment, sustainability, regulatory cooperation, and political dialogue between both regions.

This GEO-LAC event will examine the agreement in the context of the new geoeconomic order. At a time of growing geopolitical tensions, shifting alliances, technological disruption, and rising protectionism, the agreement sends a powerful signal in favor of rules-based trade, strategic interregional cooperation, and closer ties between two democratic regions. The conversation will bring together leading policymakers and trade experts who were directly involved in, or closely connected to, the process that made the agreement possible. The panel will explore why the agreement moved forward now, what challenges remain for its implementation, and how it may reshape EU–Latin America relations in a fragmented global economy. 

The discussion will address the commercial, political, and strategic implications of the agreement, including its potential effects on trade flows, investment, value chains, sustainability, environmental cooperation, and regional integration within Mercosur.
