The long-awaited amendments to Thailand’s competition law were published in the Royal Gazette on 7 July 2017 and will become effective on 5 October 2017. The new Trade Competition Act B.E. 2560 (2017) ("2017 Act") will repeal and replace the first competition law in Thailand, the Trade Competition Act B.E. 2542 (1999), which remains in force until the effective date of the 2017 Act. Further implementing regulations and notifications will also need to be issued in order to clarify the full scope of the 2017 Act. The 2017 Act is expected to herald increased enforcement.
