TikTok owner Bytedance accused Chinese technology company Tencent of blocking links to its products, prompting questions about Tencent's governance and its compliance with competition law.

In a lengthy online post (in Mandarin), Bytedance said Tencent had been blocking traffic from its mobile social services WeChat and QQ to its own short-form video applications Douyin, Huoshan, and Xigua., for three years, “affecting more than 1 billion users.” 

The tussle between the two Chinese tech companies came amidst increased scrutiny of anti-competitive behaviour in the technology industry by the Chinese government. 

Bytedance is not the only company in Tencent's sights; the technology company has also been accused of prohibiting users from opening links to Alibaba’s Taobao and Tmall online marketplaces.

Bytedance said that Tencent's practice of blocking links to competitor sites has been going on for years.
