Shpetim Bajoku was convincing against the boxer of Serbia, Semir Alicic, in the Balkan Championship that started on Wednesday.
Bajoku was the best in the three rounds, in the fight of the category up to 67 kilograms.
After the ring judge declared Bajuk the winner, the Serbian boxer did an unsportsmanlike act. He did not extend his hand to the boxer from Kosovo.
Balkanik is being held in Albena, Bulgaria.
Bajoku defeated the Serbian in June in a tournament in Kumanovo. Bajoku has his next fight on Saturday.
