The Mercosur agreement with the European Union has come into effect after over twenty years of negotiations, presenting significant trade opportunities for Portugal and Brazil. Key benefits include lower tariffs, reduced bureaucracy, expanded access to the agri-food market, enhanced service opportunities, better conditions for public procurement, improved brand protection, integrated production chains, attraction of Brazilian investment to Portugal, increased regulatory stability, and strategic market positioning. This agreement not only facilitates trade but also positions Portugal as a vital Atlantic business platform, leveraging its historical ties and language advantages with Brazil.
