Abstract. The Union for the Mediterranean (UfM) suggested by Nicolas Sarcozy, the Ex-President of France, has been generating many questions from the very beginning. As experts note, this was due to the unsuccessful project kick-off. Since its first years, the Community model proposed to the Mediterranean countries appealed to solution of the most important problems by joint efforts. Common immigration policy, economic and trade development, common legal rules support, environmental protection and cooperative development were meant to be the "backbones" of the project. Investigating difficulties and perspectives of the European countries cooperation the author points that the UfM represents a promising tool for the energy problem solution. The Europe's energy market diversification program and, therefore, its security largely depends on how successfully the European partners will be able to make advantage of it.
