Djordje Djokovic says Belgrade already have plans to become an ATP 500 event in the coming years as the city looks to invest in tennis.
The 250 event has returned to the ATP schedule this year with Djordje, brother of world number one Novak Djokovic, appointed tournament director for the event.
He, though, says this is just the start, with Belgrade looking to become an important hub for tennis moving forward.
Novak Djokovic, Dominic Thiem, and Aslan Karatsev have confirmed they will play the event, which starts April 19, and Stan Wawrinka was also set to play before injury.
"We have invested great efforts to bring an ATP tournament back to Serbia and organize it at the highest level in accordance with the measures of the Government of Serbia and the ATP," Djordje said.
"This is just the beginning, our goal is for the tournament to get a Tour 500 license in the coming years.
"The response of the players is good, especially considering that another tournament is being played in Barcelona at the same time."
Djokovic also confirmed that Belgrade has secured a WTA event, scheduled for May 16. Additionally, there will be both a men's and women's challenger event this summer.
Additionally, for every ace served at the ATP event, a donation will be made by organisers to the Novak Djokovic Foundations.
