President Aleksandar Vucic described the parade as "a source of pride for Serbia.” It included some 10,000 personnel and 2,600 pieces of military equipment. The government said the parade was to mark a national holiday -- the Day of Serbian Unity, Freedom, and the National Flag. But Vucic has continued to cultivate his multi-vector approach to foreign and defense policy, cultivating ties with both Moscow and China. Along with Russian President Vladimir Putin, he was in China earlier this month for celebrations marking the end of World War II that also included a massive military parade in Beijing. Serbia also uses Chinese military equipment, such as CH-92A combat drones.
