On 24 February 2017, the Government Procurement and Supplies Management Act, B.E. 2560 (2017) (the Act) was promulgated in the Royal Gazette. It will become effective 180 days after the publication.

Until the effective date, the Regulations of the Office of the Prime Minister on Procurement, B.E. 2535 (1992), and related regulations will remain effective to the extent that they are consistent with the Act. The Act specifies that related regulations are to be issued within one year from the effective date. If the existing regulations conflict with the new Act and cannot be enforced, the responsible government agency is empowered to proceed as prescribed by the policy committee appointed under this Act.

The Comptroller General's Department is now in the process of drafting the related regulations, which are expected to be announced and become enforceable around the effective date of the Act to avoid any interruption in the enforcement of this Act.
