Huawei

Huawei is a Shenzhen-based technology company and the world's largest maker of telecommunications equipment. Founded in 1987 by Ren Zhengfei, it now spans carrier networks, enterprise ICT, cloud computing, digital power, and a consumer business that builds smartphones, wearables, and the homegrown HarmonyOS operating system. Despite years of U.S. sanctions, the company posted roughly 880.9 billion yuan in 2025 revenue and pours over a fifth of that back into R&D.
