NATO Secretary-General Jens Stoltenberg has arrived in Serbia for a three-day visit.
Serbian Defense Minister Aleksandar Vulin welcomed Stoltenberg in the capital, Belgrade, on October 6.
Stoltenberg will meet Serbian President Aleksandar Vucic and Prime Minister Ana Brnabic during his trip.
Stoltenberg and Vucic will also attend the opening ceremony of the civil emergency exercise "SRBIJA 2018," which is co-organized by the NATO Euro-Atlantic Disaster Response Coordination Center and Serbia's Interior Ministry.
Ahead of his trip, Stoltenberg said EU-mediated talks between Serbia and neighboring Kosovo were important for peace and security in the region.
Belgrade and Pristina in 2013 committed to EU-mediated talks to resolve their differences, but little progress has been made.
There have been continued tensions between Serbia and Kosovo, a former Serbian province that declared independence in 2008.
Kosovo's independence has been recognized by more than 100 countries, but not by Serbia.
