WARSAW, May 3 (Xinhua) -- The European Union (EU) should integrate its energy sectors as energy security is a crucial element of national security, Polish Defence Minister Radoslaw Sikorski said on Wednesday.

    Sikorski made the remarks in response to a question about his recent criticism of the German-Russian Northern Pipeline project, the Polish News Agency reported.

    Sikorski also announced that his ministry would soon take steps aimed at diversifying Poland's energy sources.

    On Sunday, the defense minister criticized the German-Russian project to build a gas pipeline under the Baltic seabed, because it bypasses Poland, describing the move as being "disloyal toward other EU countries."

    He implicitly related the envisaged project to the Molotov-Ribbentrop pact signed in Moscow in 1939. Sikorski's words have brought criticism from German politicians and media, as well as the European Commission. Enditem
