Chinese police officers patrolled the streets of Belgrade alongside their Serbian colleagues, Sunday.
Joint Chinese-Serbian patrols have reportedly been introduced to help local forces cope with a growing number of Chinese tourists and the language barriers that result.
One tourist from China said, "We are very surprised we can see Chinese police officers here, and we are very excited."
Joint patrols could be seen across the Serbian capital, including the city's main pedestrian and shopping zone Knez Mihailova Street, Belgrade's central park and fortress Kalemegdan, the Nikola Tesla Airport and the neighbourhood Block 70, where the city's China Town is located.
Such patrols have also reportedly been deployed in the Serbian cities of Novi Sad and Smederevo.
Each year, Belgrade and other Serbian cities draw thousands of Chinese tourists.
