Prague - The European Union's top diplomat on Friday urged Armenia and Azerbaijan to use the "good vibrations" of a newly- founded EU project to help solve their long-running conflict over the region of Nagorno-Karabakh.

On Thursday, the EU launched its so-called "Eastern Partnership" with Armenia, Azerbaijan, Belarus, Georgia, Moldova and Ukraine at a summit in Prague.

And "without any doubt, the atmosphere that can be produced, that can be created in this kind of meeting will create good vibrations, and out of good vibrations sometimes comes love," EU foreign-policy chief Javier Solana told journalists after talks with the presidents of the two countries and their neighbour Turkey.

The conflict in Nagorno-Karabakh dates back to the collapse of the Soviet Union, when fighting broke out between the region's ethnic- Armenian majority and the central government of Azerbaijan, to which it belongs under international law.

The phrase "good vibrations" originates with the Beach Boys hit song of the same name in 1966.
