China on Sunday put into effect new antitrust guidelines targeting internet platforms, subjecting the countryโ€™s tech industry to tougher rules on competition.

Why it matters:ย The guidelines formalize earlierย draft rulesย announced by Chinaโ€™s State Administration for Market Regulation (SAMR), the nationโ€™s top trustbuster.

  • Some of the countryโ€™s top internet-based services, including Ant Groupโ€™s Alipay, food delivery app Meituan, Tencentโ€™s instant-messaging app WeChat, and online marketplace Taobao, will be subject to the new guidelines.ย 

Details:ย The new rules forbid internet platforms from forcing merchants intoย exclusivity deals, offering different prices based on user data, and using algorithms to manipulate the market.

  • Pricing products or services differently according to customer purchasing power, consumption history, or user preference is now considered monopolistic behavior, according to the guidelines.
  • The guidelines widen the parameters for determining a firmโ€™s โ€œmarket-dominant positionโ€ to include factors such as transaction volume, user base page views, and technological barriers.ย 
  • SAMR, which issued the rules, said the guidelines will provide aย legal basisย (in Chinese) for the country to tighten antitrust regulation of internet platforms.

Context:ย In December, SAMRย issuedย fines to Alibaba and affiliates of Tencent and logistics giant SF Express over three separate acquisition deals, a move that legal experts described as the countryโ€™s first batch of antitrust enforcements against tech firms.

  • SAMR in January 2020 proposed anย overhaulย of the countryโ€™s Anti-Monopoly Law to include internet firms in the scope of antitrust regulations.
  • Last week, Douyin, ByteDanceโ€™s Chinese version of TikTok, said it hadย suedย Tencent for monopolistic behavior including blocking Douyinโ€™s content on WeChat.
