China has imposed a landmark antitrust penalty on Trip.com Group, the country’s largest online travel agency, in a move that underscores Beijing’s ongoing scrutiny of platform power.

According to Skift, the State Administration for Market Regulation (SAMR) fined Trip.com RMB 5.2 billion ($770 million) — the most significant platform fine since Alibaba’s $2.6 billion penalty in 2021.

The regulator found that Trip.com used traffic-allocation mechanisms, platform rules, and technical measures to secure exclusive agreements with hotels. It also enforced ‘lowest price across the internet’ arrangements, effectively preventing hotels from offering better deals on rival platforms.

The penalty includes confiscation of RMB 1.66 billion ($250 million) in illegal gains, a fine of RMB 3.52 billion ($520 million) — equivalent to 7.5% of Trip.com’s 2025 revenue from Mainland China — and an order to refund RMB 122 million ($18 million) in hotel security deposits that had been collected.

This case signals that China’s antitrust campaign is extending beyond e-commerce and tech giants into the online travel sector. The SAMR’s action puts new scrutiny on how platforms use exclusivity, pricing, and traffic allocation to maintain competitive advantages.

For travelers and the tourism industry, the ruling may lead to more competitive pricing and greater choice as hotels regain freedom to list on multiple platforms. However, the immediate impact on Trip.com’s operations and market position remains to be seen.

As China continues to refine its regulatory framework for digital platforms, the Trip.com case serves as a clear warning: no sector is immune from antitrust enforcement when platform power is perceived to harm competition and consumer welfare.
