Thailand’s Newly Proposed Public-Private Partnership Law

Informed Counsel

Development of public infrastructure has been increasing in line with Thailand’s economic growth, and the private sector has played an important role in this regard. However, the existing law governing Public-Private Partnerships (PPP) is somewhat unclear and unsuitable for the current economic climate.

PPP refers to a government or state enterprise’s project in which the private sector participates or jointly invests. Generally, PPP involves infrastructure development in sectors such as power and electricity, telecommunications, water, sanitation, and transport. PPP in Thailand is governed by the Private Participation in State Undertaking Act B.E. 2535, which has been effective since April 1992. The purpose of this legislation is to prevent corruption, because in the past, granting approvals or concessions for private sector entities to participate in government projects was subject to the consideration of only one government agency. In relation to private participation, the government may grant the concession, approval, or rights to a private sector entity via different forms, depending on the appropriateness of each project. Examples of high-profile PPP projects in Thailand include the Electricity Generating Authority of Thailand, the BTS SkyTrain, and the Don Muang Tollway.

The Private Participation in State Undertaking Act

The Private Participation in State Undertaking Act applies to private participation in state projects which involve funds or assets valued at THB 1 billion or more. However, state undertakings with funds or assets worth less than THB 1 billion may have to comply with this law if the Council of Ministers (i.e., the Cabinet) deems appropriate.

The procedures for PPP projects under this statute are divided into three steps: (1) project initiation; (2) selection of a private sector entity; and (3) project monitoring. The approval process of a PPP project is summarized below:

  1. Project Study. The project agency must conduct a study and analysis of the project and present it to the responsible Minister of the project agency for approval. It will be then submitted to the Office of National Economic and Social Development or the Ministry of Finance, depending on whether the project is a new or existing project.
  2. Approval by the Cabinet. After consideration by the Office of National Economic and Social Development or the Ministry of Finance, the project will be submitted to the Cabinet for approval.
  3. Invitation for Private Participation. Once the Cabinet grants approval, the project agency will prepare an invitation letter for private participation in the project. A committee will also be appointed by the project agency for the next stage of the selection of private sector entities.
  4. Selection Process. Once selection of a private sector entity, conducted by the appointed committee, is final, a draft agreement between the project agency and the selected private entity must be prepared and approved by the Office of the Attorney General.
  5. Final Approval by the Cabinet. The result of the selection, draft agreement, and relevant information must be submitted to the Cabinet again for final approval.

As the law stipulates a long consideration process and the involvement of many government agencies, it may take up to two years to initiate a PPP project. In addition to these approval delays, there are also some practical problems with the application of the current law to PPP projects. The Private Participation in State Undertaking Act contains only 25 sections, while the number of PPP projects is dramatically increasing. The definitions of many terms in the Act are not provided or clearly specified, for example, “project,” “the project’s value or asset,” or “new and existing project.” The calculation of a project’s value is not defined, the consideration process is lengthy, the governing framework is unclear, and there is no provision for the amendment or renewal of an agreement between the public and private sector. In addition, there is no central agency to provide support to PPP projects.

Newly Proposed PPP Law

In order to repeal the existing legislation and help address the problems in connection with PPP projects, a new PPP law has been proposed, called the “Private Joint Investment in State Undertaking Act.” The bill was approved by the Cabinet on April 10, 2012, and sent to the House of Representatives for their approval on a fast-track consideration basis. If the draft is approved by the House of Representatives, it will be further sent to the Senate for final approval, and once granted, announced in the Government Gazette by the Prime Minister and will subsequently become effective. The draft new PPP law, as it currently stands, contains the following key provisions:

  • The Private Participation in State Undertaking Act B.E. 2535 will be repealed.
  • The Committee of Private Investment in State Undertaking will be appointed to set up policies and strategic plans in connection with PPP projects and to approve PPP projects, instead of the Cabinet.
  • More specific definitions of terms will be provided (e.g., “state undertaking”).
  • The consideration procedure will be shortened and a time period for consideration will be set. Only approval from the Cabinet is required, while approval of the draft agreement between the project agency and the selected private entity by the Office of the Attorney General will no longer be required. The entire process for approval of a PPP project will be approximately seven to twelve months, instead of two years.
  • Projects will not be classified as a new or existing project.
  • The conditions and criteria to calculate a project’s value will be subsequently announced by the Ministry of Finance.
  • Clauses to amend and renew an agreement between the public and private sector will be provided.
  • The project development funds to support the PPP project will be established as a source of funds for the government, rather than an annual government statement of expenditures. The funds will be used for the preparation of a strategic plan and consideration of the project’s feasibility.

With more streamlined procedures and clearer guidelines, if and when the bill is passed by the relevant authorities, it will be a significant development for Thailand’s PPP projects, and will hopefully strengthen the country’s infrastructure sector.

The Myanmar Investment Commission (MIC) has issued a notification that gives investors with projects in Myanmar clearer guidance for securing approval and for changing, expanding, or exiting an approved project. Issued on August 19, 2026, MIC Notification No. 5/2026 replaces MIC Notification No. 26/2021 and sets procedures for state or regional investment committees to review, approve, and supervise investment projects, including project amendments, investment increases, land-use rights applications, compliance inspections, and suspension or termination of approved businesses. Endorsement Application Timeline and Deemed Acceptance In Myanmar, prospective investors seeking approval under the Myanmar Investment Law generally do so through an MIC permit or an MIC endorsement, depending on the nature of the investment. While certain large-scale investment projects require an MIC permit, projects that are not required to obtain an MIC permit may instead apply for an MIC endorsement. Investors seeking MIC endorsement for their planned projects typically submit their applications to the relevant state or regional investment committee. These committees are established under the Myanmar Investment Law and are authorized to approve investments of less than USD 5 million, subject to the project’s nature and location. MIC Notification No. 5/2026 specifies that upon receiving an endorsement application, the relevant investment committee office will check it for completeness and determine whether it can be considered at the state or regional level or must be referred to the MIC; if it must be forwarded to the MIC, this will be done within 10 working days. If an application is within its purview, the committee may reject the endorsement application within 15 working days of receipt; otherwise, the application is deemed accepted. If approved, the endorsement certificate will be issued within 10 working days of the approval decision, subject to applicable procedures. Endorsement Certificate Amendment The notification clarifies which amendments a state

Certain securities, derivatives, and treasury activities in Thailand were opened to foreign investors when Thailand’s Ministry of Commerce published two new ministerial regulations in the Government Gazette on August 28, 2026. The regulations significantly broaden the service activities that foreign-owned businesses may conduct without a license or certificate under the Foreign Business Act B.E. 2542, as amended (FBA). Securities and Derivatives Business Exemptions Prior to the issuance of these ministerial regulations, the exemptions covered (1) securities brokerage and derivatives brokerage with their only underlying assets being agricultural commodities, financial instruments, and securities; and (2) dealers, advisers, and fund managers conducting derivatives business under Thailand’s derivatives laws. The ministerial regulations provide broader exemptions. In addition to derivatives under the laws on derivatives as before, the following two major categories are provided: Derivatives whose underlying assets or variables fall outside the scope of Thailand’s laws on derivatives. This addresses a gap in the previous framework, which did not comprehensively exempt derivatives tied to nonregulated underlying assets or variables, such as certain commodities. Foreign brokers, advisors, and fund managers can now facilitate a broader range of hedging and risk management instruments without triggering FBA licensing requirements. Derivatives traded outside a derivatives exchange, or over the counter (OTC), whose payments are calculated by reference to foreign exchange rates or interest rates. This removes an FBA licensing barrier for foreign providers of widely used OTC hedging products, broadening the solutions available to importers and exporters managing currency exposure and to borrowers seeking greater certainty over financing costs. The ministerial regulations also exempt brokers and agents handling transactions involving either of these two derivatives categories. For securities businesses, the ministerial regulations add exemptions for margin loans used to purchase securities and for securities repurchase transactions. These additions clarify whether such activities qualify as exempt brokerage

Foreign business restrictions on telecommunications, treasury center businesses, and intragroup support services were eased when Thailand published the Ministerial Regulation Prescribing Service Businesses Not Requiring Permission for Foreign Business Operations (No. 5) B.E. 2569 (2026) in the Government Gazette on August 28, 2026. The ministerial regulation expands the categories of service businesses that foreign investors may operate without a foreign business license (FBL) under the Foreign Business Act B.E. 2542 (1999) (FBA). Of particular relevance to the telecommunications, fintech, and technology sectors, the ministerial regulation exempts: Type 1 telecommunications licensees, which do not have their own networks; Treasury center businesses operated in accordance with Thailand’s exchange control regulations; and Certain intragroup administrative, human resources, and information technology management services. Telecommunications Services Foreign-owned businesses providing telecommunications services under a type 1 telecommunications license may now operate without obtaining an FBL. This may streamline market entry for qualifying telecommunications and digital infrastructure businesses. The exemption applies only to the FBA licensing requirement. Operators must continue to comply with applicable requirements under the Telecommunications Business Act and the regulations of the National Broadcasting and Telecommunications Commission, and the change does not affect foreign ownership restrictions applicable to type 2 or type 3 telecommunications businesses. Treasury Center Businesses The ministerial regulation also exempts qualifying treasury center businesses from the FBL requirement. This may facilitate centralized treasury functions in Thailand, including liquidity management, foreign exchange management, and intragroup funding arrangements. Treasury center operations remain subject to applicable requirements of the Bank of Thailand and other competent authorities. Intragroup Administrative, HR, and IT Services Certain administrative, human resources, and information technology management services provided between affiliated entities are also exempt, provided the relevant entities satisfy prescribed ownership or management criteria. The exemption is available where the service provider and recipient are related through specified ownership

Thailand has taken another step toward liberalizing its foreign business framework, exempting additional service activities and derivatives brokerage or agency businesses from the licensing requirements of the Foreign Business Act (FBA). Since the FBA came into effect, Thailand has taken a measured approach to opening its economy to foreign investment. While the FBA regulates foreign participation in businesses that may affect domestic interests, the framework has also evolved to allow foreign participation in certain business activities where sector-specific laws and regulatory frameworks already provide sufficient oversight, making additional FBA restrictions unnecessary. This is particularly true where Thai businesses are sufficiently capable of competing in certain service sectors, or where liberalization is intended to facilitate the provision of services among companies within the same corporate group. Against this backdrop, two new ministerial regulations have been issued pursuant to the FBA. Service Businesses Under the FBA Under the FBA, certain categories of business are restricted for foreign operators. List 3 of the FBA sets out businesses that foreigners may operate only if they obtain a foreign business license (FBL) or a foreign business certificate (FBC), or unless a specific exemption applies. List 3 (21) covers “other service businesses,” which is a catch-all provision that captures a wide range of service businesses not specifically enumerated elsewhere in the FBA. In practice, this means that most service activities carried on by foreigners in Thailand require an FBL or FBC unless otherwise exempted. Notwithstanding the foregoing, the FBA provides a mechanism to address this breadth by empowering the Minister of Commerce to issue ministerial regulations excluding specific types of service businesses from List Three (21). Once a service business is so excluded, foreigners may operate it without obtaining an FBL or FBC. Prior to the new regulations, four ministerial regulations had been issued to
