Amid Russia’s assault on Ukraine, China is delivering arms to Moscow ally Serbia. A fleet of six Y-20 cargo planes of the Chinese PLA Air Force was spotted in Serbia, as per reports. China reportedly delivered the FK-3, the export version of its HQ-22 surface-to-air missile system to Serbia. This would make Serbia the first operator of Chinese missiles in Europe. The West is concerned that the arming of Serbia by Russia and China could push the Balkan country towards another war.
