JD.com, for instance, has accused bigger rival Alibaba of unfairly locking in exclusive agreements with merchants, which Alibaba has denied. Regulators have investigated the legality of Cheng Wei’s Didi Chuxing acquiring Uber Technologies Inc.’s Chinese business. And Tencent’s WeChat dominates many aspects of daily Chinese life from payments to gaming, though ByteDance, co-founded by Zhang Yiming, has in recent years begun to eat into its advertising business through video service Douyin and news platform Toutiao.
Alibaba and Tencent now dominate e-commerce and gaming, but are also key backers of leaders in adjacent businesses such as Wang Xing’s Meituan and car-hailing leader Didi. They’ve together invested billions of dollars in hundreds of up-and-coming mobile and internet companies, gaining kingmaker status in the world’s largest smartphone and internet arena by users. Companies like ByteDance and Tencent-rival NetEase Corp., controlled by William Ding, that have risen to prominence without backing from either of the pair are viewed as rare exceptions. In other areas, Robin Li’s Baidu Inc. dominates online search.
