This article explores the ethical dimensions of European Cross-Border Cooperation (CBC) through the lens of Aristotelian philosophy, emphasizing its significance for European integration. It critiques the European Union's approach to CBC, which traditionally emphasizes economic and political advantages, advocating instead for a deeper incorporation of ethical values. Drawing on Aristotle's concepts of justice, friendship, and the common good, the article argues for a CBC that goes beyond mere economic collaboration, fostering a genuine sense of community and enhancing regional interactions and integration. By embedding these ethical considerations, CBC can profoundly impact the quality and sustainability of inter-regional relationships within the EU.
