Acknowledging the solid historical ties, the good neighborly relations and long-lasting people-to-people contacts that unite Bulgaria and Romania,

Recalling the importance of the Treaty of Friendship, Cooperation and Good Neighbourliness between the Republic of Bulgaria and Romania, signed in 1992, that we celebrated last year at its 30th anniversary,

Reaffirming the unwavering support for the principles of the UN Charter, the Helsinki Final Act and the Paris Charter, which underpin the rules-based international order,

Taking into account the two countries’ membership in the European Union and NATO, their commitment to the fundamental values and the common interests that the Republic of Bulgaria and Romania share at European, regional and international level,

Building upon the solid cooperation developed in the fields of common interest and taking into account the existing potential to further increase and expand it in a mutually beneficial way,

Considering that Russia’s brutal war of aggression against Ukraine has resulted into a deteriorated security context, including in our region, while reaffirming the goals for peace, prosperity and security of their peoples,

Emphasizing the importance of active regional cooperation, as the basis for lasting stability and security in South-East Europe,

Reiterating their resolve to support stability and security in the Black Sea region,

Bulgaria and Romania have decided to establish a new consolidated framework to their bilateral relation at the level of Strategic Partnership, in order to further foster their cooperation bilaterally and within the European Union, NATO and other regional and international fora, which are reflected by the following lines of approach and action:


Based on the already active and regular political dialogue, including through the five meetings of the High – Level Cooperation Council between the Bulgarian and the Romanian Governments, both countries express the common will to further consolidate their cooperation. To this end, they will consult regularly on issues of mutual interest and will aim to organize periodic meetings of the High-Level Cooperation Council.

While the economic ties are strong, Bulgaria and Romania commit to work closer to further harness the potential of their bilateral exchanges and identify together new opportunities for trade and investment promotion, economic cooperation, including market access to third countries with common products, and tourism.

Bulgaria and Romania will work to further strengthen bilateral cooperation in the field of tourism and promote participation in joint projects and initiatives.

The Strategic Partnership requires considerable improvement of connectivity across the common border in the fields of transport, infrastructure, energy, telecommunications etc. In this context, the construction of the new cross-border bridge over the Danube River near Ruse – Giurgiu, as well as the implementation of the FAST DANUBE Project will bring significant benefits for both countries, the region and the EU as a whole. Therefore, Bulgaria and Romania will further enhance their efforts to expedite the realization of both these already envisaged projects, and will continue to cooperate closely with a view to implementing other concrete projects in the field of connectivity.

Both countries will join forces to enhance the cooperation in the field of energy, while exploring ways to improve energy inter-connectivity within the region, especially, considering the new regional outlook of energy supply and distribution following the full-scale military aggression of Russia against Ukraine.
