Putin will be the special guest of a Southeast European Energy Summit.
"Like every other region, Croatia wants to make a step forward in development and secure energy sources and this is what we want to talk about," Mesic said while visiting the Montessori elementary school.
Speaking of the transfer of energy sources, Mesic said Croatia must have different supply routes. He confirmed that he and Putin would discuss Druzba Adria, a pipeline that would run from Russia to the Omisalj terminal on the Croatian island of Krk, and an LNG terminal.
