Cross-Border Cooperation (CBC) is a concerted process of building neighbourly relationships between local stakeholders and authorities on both sides of national borders. It is a highly heterogeneous process in terms of relations, actors, institutional settings, legal frameworks and financial tools involved.

CBC is not about conveying additional powers to border communities or authorities. Rather, CBC is a more efficient way of exercising their powers and implementing actions which are effective, efficient and coherent. The goals of CBC is overcoming a problem shared by communities, that happen to be divided by national borders.
