China has stunned the Saudi defence exhibition in Riyadh by unveiling a powerful lineup of next-generation unmanned war machines, signaling Beijing’s aggressive push into the Middle East arms market. The spotlight was stolen by the Wing Loong-X, promoted as the world’s first anti-submarine warfare drone, offering 40-hour endurance and massive maritime surveillance range. China also showcased the long-endurance CH-9 strike drone, highlighting how unmanned warfare is rapidly becoming the region’s new arms race as tensions grow across the Gulf.
