China Competition Law: OTA Giant Ctrip is Fined for Algorithmic Vertical Restraints

Published 6 August 2026 Xia Yu
On 25 July 2026, the State Administration for Market Regulation of China (“SAMR”) issued its administrative penalty decision (Guo Shi Jian Chu Fa [2026] No. 29) against Trip.com Group Limited (“Ctrip”). SAMR determined that Ctrip had abused its dominant position in the market for online hotel booking platform services in China by implementing exclusive dealing arrangements and a “lowest-price-across-all-platforms” requirement. These practices were found to constitute, respectively, exclusive dealing prohibited under Article 22(1)(iv) of the Anti-monopoly Law of the People’s Republic of China (“Anti-monopoly Law”) and the imposition of unreasonable trading conditions prohibited under Article 22(1)(v) of the Anti-monopoly Law. The total financial penalty exceeded RMB 5.1 billion (approximately US$768 million).
Procedurally, the case moved with notable efficiency – the investigation was opened in January 2026, the penalty notice was served on 19 July, Ctrip waived its rights to statement, defense, and hearing, and the final decision was issued and published in full on 25 July. Ctrip publicly stated that it “sincerely accepts and firmly complies” with the decision. This procedural efficiency was supported by a comprehensive evidentiary record, including contracts, technical documentation, algorithm source code, and witness statements from hotel operators. Substantively, this is China’s first administrative enforcement case in which vertical restraints implemented primarily through algorithmic automation were comprehensively characterized as an abuse of market dominance against an online travel agency (“OTA”). The case demonstrates a distinctive Chinese regulatory approach in areas such as the algorithmic evolution of most-favored-nation (“MFN”) clauses and the standards for determining the illegality of “incentivized exclusivity”. Institutionally, the penalty logic and remedial measures adopted in this case also enrich the global antitrust enforcement toolkit for platform economies.
Case Overview
Ctrip, incorporated in the Cayman Islands in March 2000, operates platforms including Ctrip and Qunar, with core businesses spanning hotel bookings, transportation ticketing, and travel packages. In January 2026, SAMR opened an investigation based on a complaint regarding suspected abuse of market dominance. The penalty notice was served on 19 July 2026; Ctrip waived its rights to statement, defense, and hearing; and the final decision was issued on 25 July.
SAMR defined the relevant market as the market for online hotel booking platform services within China. In doing so, it sequentially excluded three categories of alternative channels: offline hotel booking services, hotel-operated direct online booking services, and online hotel booking aggregator platform services, on the grounds of material differences in service mode, coverage, matching efficiency, and supply-side barriers to entry. Based on this market definition, SAMR found that Ctrip possessed market dominance based on seven factors: (1) sustained transaction volume and revenue shares exceeding 50% from 2020 to 2025; (2) a highly concentrated market structure (HHI consistently above 4,000, CR3 at 94%–95%); (3) multi-dimensional control over pricing, traffic, distribution channels, and room inventory; (4) substantial financial resources and advanced technological capabilities; (5) significant lock-in effects on hotel operators using the platform; (6) high barriers to market entry; and (7) the ability to leverage its position in adjacent markets such as transportation ticketing.
SAMR found that Ctrip had engaged in two categories of abusive conduct since 2020:
1. Exclusive dealing arrangements for “Special Tag” mid-to-high-end hotels: Ctrip induced hotels to accept the “Special Tag” designation through traffic prioritization and other incentives, required that “all room inventory” be distributed exclusively through Ctrip’s platform, and enforced compliance through manual monitoring, technical surveillance, and escalating penalties ranging from traffic restriction to de-listing. More than 90% of “Special Tag” hotels long-term complied with the exclusive dealing requirement.
2. “Lowest-price-across-all-platforms” obligations for “Gold Tag” and “No Tag” hotels: For “Gold Tag” hotels, Ctrip required prices at least RMB 20 or 5% lower than on competing platforms; for “No Tag” hotels, it required prices no higher than on competing platforms. Ctrip enforced these obligations through algorithmic tools including the “Price Adjustment Assistant”, “AI Business Assistant” and “Tagging System” which automatically monitored competitor pricing and adjusted Ctrip’s prices without hotel consent, backed by traffic penalties and reserve fund deductions for non-compliance.
The final penalty consists of an order to cease the above violations; and an order to refund RMB 122,781,078 (approximately US$18.2 million) in reservation deposits improperly withheld from hotel operators; disgorgement of illegal gains of RMB 1,658,058,958 (approximately US$245.7 million); and a fine of RMB 3,521,824,686 (approximately US$521.9 million), representing 7.5% of Ctrip’s 2025 China turnover (approximately RMB 46.96 billion, or US$6.96 billion). The total amount forfeited and fined is RMB 5,179,883,644 (approximately US$767.7 million).
“Special Tag” Exclusive Dealing: Traffic Allocation Mechanisms and the “Voluntariness” Defense
Ctrip’s “Special Tag” exclusive dealing mechanism operated through a three-tiered structure of “incentive – lock-in – penalty”. At the incentive tier, Ctrip embedded tag type directly into its search ranking algorithm, creating a rigid traffic allocation hierarchy of “Special Tag > Gold Tag > No Tag”. “Special Tag” hotels received priority placement in search results, greater traffic exposure, and increased transaction opportunities. Ctrip also provided additional incentives including “dual business district recommendations, marketing vouchers, and curated positive reviews”. The investigation revealed that a substantial number of hotel operators accepted the “Special Tag” designation in response to these incentives.
At the lock-in tier, Ctrip made exclusive cooperation a condition of the “Special Tag” designation, requiring “Special Tag” hotels to agree that “all room inventory” would be distributed exclusively through Ctrip’s platform. The decision notes that Ctrip removed the word “all” from the relevant contractual provision but continued in practice to require exclusive dealing and to prohibit “Special Tag” hotels from operating on competing platforms. This pattern – “textual moderation in contracts, unchanged rigor in practice” – itself evidences an intent to circumvent antitrust scrutiny. More than 90% of “Special Tag” hotels long-term and stably complied with the exclusivity requirement, meaning that Ctrip had locked up the core competitive resource in the online hotel booking platform services market.
At the penalty tier, Ctrip monitored whether “Special Tag” hotels appeared on competing platforms through manual comparison and technical surveillance around the clock. Upon detection, it would first issue warnings via verbal notice or system alerts, demanding that the hotel remove its listings from competing platforms. If the hotel failed to comply within the deadline, Ctrip would impose escalating penalties including traffic restrictions, revocation of benefits, and ultimately forced de-listing. A significant number of hotel operators confirmed in the investigation that after being penalized for violating the exclusivity requirement, their traffic notably declined, transaction opportunities decreased, and revenue fell.
Ctrip argued that “Special Tag” status was a “voluntary” choice made by hotel operators based on commercial self-interest. SAMR rejected this defense, finding that Ctrip’s unreasonable traffic allocation mechanism deprived “voluntariness” of substantive meaning – to obtain greater transaction opportunities and increase revenue, hotel operators had no choice but to accept the “Special Tag” designation and the accompanying exclusivity requirement. The fact that numerous hotels were penalized for violating the exclusivity requirement itself demonstrates their desire to operate on multiple platforms. SAMR explicitly stated in the decision that “where a party has taken incentive measures such as traffic prioritization, whether the hotel operator was voluntary does not affect the determination of illegality”.
In this case, SAMR treated the “traffic allocation mechanism” as core evidence in establishing the illegality of the exclusive dealing arrangement. Traditional exclusive dealing analysis focuses on exclusivity provisions in contracts. This case reveals a more subtle but more far-reaching exclusionary tool – traffic prioritization embedded in ranking algorithms. This suggests that lack of transparency in traffic allocation mechanisms is emerging as a new antitrust compliance boundary for platforms. If a ranking algorithm incorporates incentive mechanisms conditional on exclusivity – even if formally characterized as “incentives” rather than “coercion” – once combined with a dominant position, it may be subject to a piercing review.
“Lowest-Price-Across-All-Platforms”: From Contractual Clause to Algorithmic Enforcement
Ctrip’s “lowest-price-across-all-platforms” obligation effectively upgraded the traditional MFN clause. Traditional MFN clauses typically require that a supplier’s price on a platform be no higher than on other channels (price parity). Ctrip imposed on “Gold Tag” hotels a requirement of a RMB 20 or 5% price advantage – meaning that the hotel’s price on Ctrip had to be systematically lower than on any competing platform, constituting a de facto “Super-MFN” clause. For “No Tag” hotels, the requirement was that prices be no higher than on competing platforms. In contract design, Ctrip further required hotel operators to permit it to “directly adjust prices based on market competition conditions to ensure product competitiveness”, effectively transferring pricing authority from hotels to Ctrip. The decision further notes that Ctrip amended the relevant contractual provision to state “no price discrimination” but continued in practice to maintain the price advantage requirements described above. As with the “Special Tag” pattern, contractual language became more moderate while actual enforcement remained stringent – a pattern that itself evidences abusive intent.
Ctrip enforced the “lowest-price-across-all-platforms” obligation through three channels, combining technical and manual methods. Channel one was automatic price adjustment via the “Price Adjustment Assistant” / “AI Business Assistant”. This tool automatically triggered price adjustments based on price differentials for “Gold Tag” and “No Tag” hotels across platforms, bringing Ctrip’s prices to the lowest across all platforms. Channel two was mandatory price adjustment through the “Tagging System”, which was mandatorily applied to “Gold Tag” hotels and automatically triggered adjustments whenever the RMB 20 or 5% price advantage was not met. Channel three was manual price adjustment: if Ctrip staff identified that a hotel had not met the “lowest-price” requirement, they would notify the hotel to adjust its price, or even directly adjust the price in the backend system without the hotel’s consent.
For hotels that repeatedly failed to comply with the “lowest-price” requirement, Ctrip imposed dual penalties: traffic penalties – reducing search ranking and exposure, with escalating traffic restrictions for “Gold Tag” hotels, revocation of tagging benefits, and ultimately forced de-listing; and financial penalties – deducting pre-deposited reservation reserves, totaling RMB 122,781,078 (approximately US$18.2 million) as confirmed by the investigation.
SAMR rejected Ctrip’s defenses that the practice “benefited consumers”, “prevented free-riding” and that the “Price Adjustment Assistant” was voluntary. SAMR noted that price is not the sole measure of consumer welfare. The “lowest-price” requirement distorts price mechanisms, squeezes hotel profit margins, drives a race to the bottom, and ultimately harms consumer welfare in terms of quality and service choice over the long term. Hotel operators pay commission to Ctrip, through which their promotional costs are already compensated – there is no free-riding. The investigation revealed that the “Price Adjustment Assistant” was in many cases mandatorily enabled, enabled without the hotel’s knowledge, difficult to opt out of, or automatically re-enabled after opt-out – it was not voluntarily used by hotel operators. More fundamentally, the primary function of the “Price Adjustment Assistant” is to compare competitor prices and automatically adjust prices, which in essence infringes on hotel operators’ independent pricing rights – whether it improves operational efficiency cannot justify the practice.
SAMR obtained Ctrip’s technical documentation and algorithm source code during the investigation and treated them as core evidence establishing the implementation of the “lowest-price” practice. Algorithm source code is no longer merely a technical tool – it is itself the carrier and proof of the abusive conduct – a significant evidentiary development in this case. SAMR explicitly rejected “algorithm neutrality” or “technological tool neutrality” as defenses against abuse findings. Where algorithms are designed to automatically monitor competitor pricing, compel price adjustments, and are backed by penalty mechanisms to ensure compliance, the code itself is part of the unlawful conduct.
Dual Treatment of Illegal Gains: Precise Calculation and Pragmatic Waiver
In this case, SAMR adopted a dual approach to illegal gains: for the exclusive dealing component, it waived calculation; for the “lowest-price” component, it calculated precisely down to each transaction. For the “Special Tag” exclusive dealing conduct, SAMR explicitly stated that “because it is not possible to distinguish the additional matching transactions that resulted from the party’s exclusive dealing arrangement, the relevant illegal gains cannot be calculated” and therefore did not order disgorgement for that portion. For the “lowest-price” conduct, SAMR calculated that “commission income generated from orders for which hotel prices were lowered and that ultimately resulted in completed transactions” amounted to RMB 1,658,058,958 (approximately US$245.7 million) and ordered full disgorgement. According to the decision, the calculation covered all commission from transactions where prices were adjusted downward through the “lowest-price” mechanism. This means SAMR was able to precisely identify, from Ctrip’s massive transaction data, orders that resulted from automatic price adjustments via tools such as the “Price Adjustment Assistant” and aggregate the corresponding commission.
Disgorgement of illegal gains is a distinctive remedial tool in China’s administrative-led antitrust enforcement system. This case establishes a replicable template for antitrust penalties in the platform economy context – precise disgorgement of quantifiable illegal gains, pragmatic waiver of unquantifiable portions, and supplemental deterrence through high-percentage fines based on domestic turnover.
Conclusion
In this case, SAMR established the principle that an “incentive + penalty” structure can be pierced through and characterized as de facto coercion, rejecting the “voluntariness” defense and holding that formal consent does not negate illegality in the face of traffic prioritization by a dominant platform. SAMR rejected the safe harbor of algorithmic neutrality – where algorithms are designed to automatically execute price interventions, the code itself is part of the unlawful conduct. SAMR also established a refined approach to calculating illegal gains – precise disgorgement of quantifiable portions, pragmatic waiver of unquantifiable portions – providing a methodological template for future cases.
