BELGRADE, Serbia—Serbia on Saturday publicly displayed a recently delivered Chinese anti-aircraft missile system, raising concerns in the West and among some of Serbia’s neighbors that an arms buildup in the Balkans could threaten fragile peace in the region.
The sophisticated HQ-22 surface-to-air system was delivered last month by a dozen Chinese Air Force Y-20 transport planes in what was believed to be the largest-ever airlift delivery of Chinese arms to Europe.
