Tencent-backed WeChat banned three social networking rivals within one day on its platform—including Bytedance’s just-launched video-based messaging app Duoshan—taking China’s social media war up another notch in 2019.

Other apps affected by the WeChat ban included: Kuairu Technology-owned, Smartisan-backed Liaotianbao, which is an updated version of the once-popular messaging service Bullet Messenger; and Matong, an anonymous social media app developed by Shenzhen-based Ringo.AI. All three apps were rolled out on Tuesday.

WeChat blocked the download address of Bytedance’s Duoshan for “hazardous content complaints from users.” The blocking of Duoshan came as the app was being announced by its product manager during its launch event in Beijing.
