Speaking at the Three Seas Initiative panel on the first day of the two-day forum, Pahor said he supported initiatives that connected, while adding that new divisions should be avoided.

Also participating in the panel were Hungarian President Janos Ader, Lithuanian President Dalia Grybauskaite and Bulgarian President Rosen Plevneliev.

"I see the three seas initiative as a possible answer for the crisis of the European idea, and not as a new division of Europe to the west and east, which would be bad for the European idea," Pahor said, adding that "we need more Europe".

He called on prime ministers and relevant ministers to discuss financing and implementation of joint economic, infrastructural and security projects that had been identified at the forum.

The Slovenian president also touched on the EU crisis and reiterated that he was a convinced supporter of the EU and that the institutional crisis could only be solved through measures taken at various levels.

Pahor will hold today a number of bilateral meetings on the sidelines of the forum, including with Croatian counterpart Kolinda Grabar-Kitarović and Polish counterpart Andrzej Duda.
