ByteDance accuses Tencent of blocking its work-from-home tool Feishu on WeChat
- ByteDance says Tencent is not approving a WeChat mini program for its cloud office software Feishu, known as Lark overseas
- Blocking links and user access between apps is common practice in China’s competitive tech industry

TikTok owner ByteDance has accused Tencent Holdings of blocking its cloud office suite Feishu on WeChat as China’s tech giants fight for dominance in the enterprise collaboration market and the central government increases scrutiny of monopolistic practices in the tech sector.
“The review of the WeChat open platform has always been an unsolved mystery. Even if the review status becomes ‘passed’, WeChat can block the product for no reason,” Xie said in a post on Jinri Toutiao, the company’s popular news platform, on Thursday. “Our other two WeChat mini programs, ‘Feishu Conference’ and ‘Feishu’, have suffered such treatment as well.”
“We respect Tencent’s absolute market position and influence in the social media field, but … Tencent relies on its monopoly position to block Feishu and harm the enterprise and user experience. We do not agree [with this practice],” he added.
WeChat and ByteDance did not immediately respond to requests for comment.
