June 11 (UPI) -- Serbian President Aleksandar Vucic will mark his first-ever official visit to Ukraine on Wednesday since he took the presidency nearly eights years ago to take part in a European summit.

Vucic will pay a one-day visit to Serbia's war-torn northern neighbor, where he will participate in the Ukraine-Southeast Europe Summit in Odesa, the Serbian presidential office announced.

Few official details were shared.

Meanwhile, it's expected to gather representatives from a dozen southeastern European nations, including newly-elected Romanian President Nicusor Dan, who is also on his first visit to Ukraine since his own election win last month.

European political experts say Vucic's presence signals an EU-realignment for Serbia, which has largely remained neutral, with respect to Russia's full-scale invasion and war in Ukraine.
