For two decades, the EU has sought to modernise its preferential trade relationship with the sub-Saharan African, Caribbean and Pacific (ACP) countries and establish free trade areas with regional groupings under so-called economic partnership agreements (EPAs). These are free trade agreements that allow ACP countries to continue exporting their products to the EU duty free and quota free, while ensuring full compliance with World Trade Organization (WTO) rules. EU goods should also benefit gradually from full liberalisation, though with numerous exceptions related to goods ACP countries wish to protect from external competition, particularly agricultural products.
