On 5 October 2017, the Trade Competition Act (B.E. 2560) was implemented. The Act replaces the previous Trade Competition Act (B.E. 2542) and introduces exemptions for central, regional, or local administrations, state-owned enterprises, public organisations, farmer groups, cooperatives, and businesses regulated under other sectoral laws. The Act prohibits business operators from using their dominant market position to fix prices, limit production, obstruct competition, or engage in unfair trade practices. Furthermore, businesses are prohibited from entering into joint agreements that would restrict competition in a market.
