On 3 December, South-East Europe has taken a significant step towards deeper regional integration and enhanced connectivity. Last night, Greece, Bulgaria and Romania signed a Memorandum of Understanding to boost cross-border cooperation on transport infrastructure.
The Memorandum of Understanding signals a shared determination to accelerate the modernisation and interoperability of strategic rail, road and inland waterway links. This deepening cooperation will support mobility, trade flows, economic cohesion and security across the region. The agreement established a Black Sea–Aegean Sea Corridor Platform (BACP), bringing together the three member states’ Ministers of Transport to provide strategic guidance and political coordination for its implementation. This work will be supported by the European Coordinators and EU institutions, and will be conducted at a technical level.
Commissioner Tzitzikostas said: "This commitment by Greece, Bulgaria and Romania marks a decisive step in strengthening the most strategic north–south corridor in south-east Europe. By deepening cooperation, we are strengthening connectivity for citizens and businesses and reinforcing Europe’s security, competitiveness and resilience across the Aegean, the Black Sea and the Danube. The European Commission will stand with them at every step."
Commissioner Tzitzikostas hosted the signing ceremony in Brussels. The European Investment Bank also attended the ceremony.
The Memorandum represents both a political commitment and a strategic framework that will guide cooperation in the years ahead. It foresees regular coordination at political and technical levels, exchange of information on national investment plans, and joint action to speed up priority projects of European relevance within the trans-European transport network (TEN-T).
