On March 24, 2026, the Trade Competition Commission of Thailand (TCCT) published its long-anticipated Guidelines on Multi-Sided Platforms and E-Commerce Businesses in the Government Gazette, following the conclusion of a public hearing conducted last year. The guidelines entered into force on March 25, 2026, and significantly expand the application of Thai competition law to digital platform ecosystems. These rules introduce targeted restrictions on platform conduct, such as price-ranking algorithms and tying and bunding, that leverages network effects, and will have far-reaching implications across Thailand’s digital economy—affecting not only platform operators but also platform participants, including sellers, logistics providers, advertisers, and payment service providers operating on or alongside such platforms. The guidelines clarify how existing prohibitions under the Trade Competition Act B.E. 2560 (2017) (TCA)—including abuse of market dominance, cartel conduct, and unfair trade practices—apply in the context of platform-based business models. While many provisions reflect earlier draft guidelines, the final version delivers more precise definitions and clearer enforcement parameters, increasing regulatory certainty while also raising compliance expectations. Applicability The guidelines introduce core definitions that determine their coverage: Multi-sided platform: A platform that acts as an intermediary connecting two or more groups of users, enabling them to have direct interaction in order to exchange or rely on services from one another. Examples include digital platforms for trading goods or services (e-commerce), as defined below. Digital platform for trading goods or services (e-commerce): A platform that acts as an intermediary connecting the distribution, purchase, sale, or exchange of goods or services. This includes operations carried out to facilitate transactions or interactions between business operators through an electronic transaction system, regardless of whether a service fee is charged. Operator of a digital platform business for trading goods or services: A provider of digital platform services for trading goods or services, as described

Thailand’s National Broadcasting and Telecommunications Commission (NBTC) has publicly indicated that it is preparing a new regulatory framework for data center operators that may introduce foreign-ownership restrictions. In particular, the NBTC is considering reclassifying data center operations from a type 1 telecommunications business license to a type 3 license. If implemented, this change would subject data center operators to a significantly more stringent regulatory regime, especially in relation to foreign ownership and control. The NBTC has indicated that it intends to propose a draft framework to the NBTC board. This would be followed by a public hearing process, with a view to implementing the new rules within 2026. Under the Telecommunications Business Act B.E. 2544 (2001), as amended, telecommunications businesses operating under type 3 licenses are subject to foreign ownership restrictions, including a requirement that less than 50% of the total issued shares be held by foreign shareholders. In addition, type 3 licensees are subject to foreign dominance restrictions, which prohibit arrangements that allow foreigners to dominate the business. These foreign dominance restrictions are broad in scope and may capture various forms of direct and indirect control or influence. This includes circumstances in which a foreign national is able to influence or control the formulation of policy, management, or business operations, or the appointment of directors or senior executives. At this stage, the exact scope of the proposed rules remains unclear. Businesses with existing or planned data center operations in Thailand should therefore monitor upcoming NBTC developments in this regard and prepare for the expected public hearing process.

In March 2026, the Myanmar Investment Commission (MIC) introduced two regulatory updates affecting investors planning new investments or implementing MIC-approved projects. Minimum Investment Conditions for Tax Incentives MIC Notification No. 1/202 clarifies the minimum conditions for investments in promoted sectors to qualify for tax exemptions or relief under the Myanmar Investment Law. The notification establishes the following requirements: Investors must contribute at least 35% of the total investment amount in cash, as reflected in the relevant proposal or endorsement application. Where an investment involves a foreign loan, the investor must obtain approval from the Central Bank of Myanmar, together with a loan repayment schedule, and provide evidence that both the foreign loan proceeds and the capital contribution have been remitted in cash through an authorized dealer bank. Chinese Yuan Accepted for Investment Capital The MIC also issued Investment News Bulletin No. 1/2026, confirming that Chinese yuan (CNY) is now accepted as foreign investment capital for applications for MIC permits and endorsements, in addition to US dollars (USD). Investment funds contributed in CNY may be remitted through banks authorized to deal in foreign currency in CNY, following the same process currently applied to investments made in USD. These developments may affect how foreign investment capital is structured and remitted, as well as the availability of tax incentives for investments under the MIC framework.

Thailand’s Board of Investment (BOI) now requires data center projects to demonstrate measurable benefits for local workforce development, R&D, SME capability, and domestic supply chains to qualify for corporate income tax (CIT) exemptions. BOI Notification No. Por. 3/2569, issued on February 6, 2026, updates the requirements for projects seeking promotion under BOI category 8.2.1 (data centers). All data center projects must now submit and implement plans covering development of Thai human resources and domestic supply chain support before benefiting from any CIT exemption. Human Resources Development Plan The BOI seeks to promote local talent development beyond basic training. Plans must include the following elements: Training for data center design, construction, and operations targeting vocational students, engineering and ICT undergraduates and postgraduates, and energy and building personnel in Thailand. Joint curricula with Thai universities and technical institutes. Collaborative R&D with Thai nationals or institutions in areas including AI, resource allocation, high-performance computing, and data center hardware and systems. Thai SME upskilling in electrical and energy systems and IT services. Domestic Supply Chain Support Plan Plans must demonstrate knowledge transfer in design, construction, cooling, security, and power and water management. Projects must also include usage or installation of domestically manufactured equipment or engage specialist domestic entities. Criteria for BOI Evaluation The BOI will assess data center operators’ eligibility for CIT incentives based on two criteria: Scale requirement: Training and joint-curriculum initiatives must reach a total participants equal to at least 10 times the project headcount and run for the duration of the CIT incentive. If this threshold is not met, the applicant must also implement continuous R&D or SME skills-development plans throughout the incentive period. Substantiality test: Supply-chain plans must be substantive, meet industry standards, and show measurable development of the domestic digital and data center supply base. To ensure compliance,
