TMTPOST — Trip.com Group accepted a 5.3 billion yuan ($737 million) regulatory penalty on Monday after antitrust enforcement officials determined the online travel platform abused its dominant market position through exclusive merchant arrangements. Under the administrative ruling issued by the State Administration for Market Regulation, the Shanghai-based enterprise must pay a regulatory fine of 3.521 billion yuan, equal to 7.5% of its 2025 domestic revenue. Authorities simultaneously ordered the confiscation of 1.658 billion yuan in illegal gains and directed a 122 million yuan ($17 million) refund of forcibly withheld order reserve funds to affected hotel operators. In a filing with the Hong Kong bourses, the company confirmed full acceptance of the decision, committing to comprehensive structural reforms and enhanced internal compliance frameworks across its operating units. Regulatory oversight of digital platform exclusivity underscores persistent enforcement efforts aimed at curbing uncompetitive conduct throughout the Chinese mainland. Anti-monopoly penalties of this magnitude signal that market regulators intend to maintain strict oversight over e-commerce and booking platforms, ensuring open access for merchants and third-party vendors. While compliance costs and operational adjustments may temper near-term profit margins, the enforcement action creates a more transparent pricing ecosystem across the broader domestic tourism and online travel sectors.
