The EU’s trade deal with Mercosur, signed on December 6, 2024, after 25 years of negotiations, aims to create one of the world’s largest free trade zones covering over 700 million people. Controversially, the agreement faces significant opposition from EU member states, notably France, concerned about its impact on domestic agriculture and environmental issues. The deal could lead to increased imports of agricultural products from Mercosur nations, raising competition fears among European farmers. Despite these concerns, advocates argue it could enhance economic ties and address crucial resources like lithium amid Europe’s energy transition. The ratification process is expected to be challenging.
