A Review of Ten Years of Competition Law Implementation in Hong Kong

Hong Kong’s competition law has come of age and enterprises must now take competition law compliance seriously. As Hong Kong commemorates the 10th anniversary of competition law enactment, the Hong Kong Competition Commission (the Commission) shows mastery of competition law enforcement. Strengthening ties with local and Mainland China law enforcement and authorities, including authorities in the Greater Bay Area and the Independent Commission Against Corruption (ICAC), the Commission is poised to target larger syndicates and complex cartels.

Following the implementation of the Competition Ordinance (Cap. 619) (the Ordinance) in 2015 in Hong Kong, two key conduct rules have been established to ensure fair competition in the market. The First Conduct Rule prohibits agreements, decisions, or concerted practices between undertakings that have the object or effect of preventing, restricting, or distorting competition in Hong Kong. This includes practices such as price-fixing, market-sharing, and bid-rigging. The Second Conduct Rule targets undertakings with a substantial degree of market power, prohibiting them from abusing this power through conduct that prevents, restricts, or distorts competition. Such abusive conduct may include predatory pricing, refusal to deal, and exclusivity arrangements. Collaborations with Mainland authorities aim to foster a more unified competition policy, particularly in the Greater Bay Area through the joint initiative with the Guangdong Administration for Market Regulation, targeting enterprises in the region.

In 2025, the Competition Tribunal (Tribunal) is anticipated to continue rendering decisions on more cases, establishing crucial precedents and offering enhanced clarity for Hong Kong’s business community. As exemplified by the Commission’s recent enforcement focus included combating cartel activities affecting citizens in sectors like real estate, funeral services, cleaning services, building maintenance, and logistics technology.
