As a strategic, emerging sector that converges artificial intelligence, advanced manufacturing, and new-energy technologies, the low-altitude economy has become the focal point of global technological competition and economic transformation. To seize the commanding heights of worldwide technological rivalry, foster international trade and cooperation in the low-altitude domain, and ensure the safe, healthy, and orderly development of the industry, the 8th Global Unmanned Systems Conference (GUSC2025) and the 2025 Guangzhou International Low-Altitude Economy & Trade Expo (GLE Expo 2025) will be held from 12–14 December 2025, in Hall A of the China Import and Export Fair Complex (Canton Fair Complex).Hosted by the Chinese Society of Aeronautics and Astronautics, the China Association of Defence Industry Enterprises, and the Guangdong-Hong Kong-Macao Greater Bay Area Low-Altitude Economy Industry Alliance, and organized by Guangdong Low-Altitude Economy Industry Development Co., Ltd. and other partners, the event will adopt the theme “Innovating the Low-Altitude Economy, Serving Global Trade.” It will delve into the core needs and pain points of low-altitude economic growth, orienting the program toward international and domestic trade cooperation, policy frameworks, development trends, technological innovation, international/national standard formulation, and scenario-based applications. Through targeted matchmaking, dedicated roadshows, business negotiations, and specialized forums, the conference will accelerate the deployment of low-altitude application scenarios, deepen synergies across the industrial and supply chains, and foster a new, dual-circulation ecosystem for low-altitude import-and-export trade, propelling the high-quality development of the low-altitude economy.
