German Chancellor Angela Merkel is visiting Serbia and Albania shortly before her long-lasting mandate as head of German's government comes to an end.
The gesture is seen as giving significance to the six Western Balkan countries, although none of them managed to join the EU club during Merkel's term, which began in 2005.
After dinner with Rama and Zaev, Vui told the citizens of Serbia that the Open Balkans cannot be stopped because no one can find fault with it.
"These 17 squares in which we are now present the territory of Serbia. We are talking about the Open Balkans, about many initiatives, about how our citizens can live better," said Vucic.
