Members of Serbian Fed Cup and David Cup teams were handed over diplomatic passports by Serbian Foreign Minister, Vuk Jeremic, during the Serbia Open ATP event in Belgrade. WTA players Bojana Jovanovski and Ana Jovanovic were present at the ceremony, beside their male colleagues Janko Tipsarevic, Nenad Zimonjic, Viktor Troicki and Novak Djokovic. The best two Serbian WTA players, Ana Ivanovic and Jelena Jankovic, did not attend the official event, but they will receive the passports.
Here's one part of Vuk Jeremic’s statement, whose initiative will allow Serbian tennis players to travel more easily:
I am honored to promote to diplomatic service people who have contributed to the popularity of Serbia in the world [...] there is not a single country in the world which wouldn’t be honored to have you as ambassadors.
