Thailand has introduced a new set of trade competition guidelines governing multi-sided digital platforms under the Trade Competition Act, representing a significant evolution in the country’s regulatory approach to the digital economy. The measures are designed to address increasing concerns around market concentration, platform dominance, and anti-competitive conduct in rapidly expanding sectors such as e-commerce and social commerce.
The framework specifically targets large-scale platform operators—including e-marketplaces and integrated digital ecosystems—where network effects have enabled control across multiple layers of the value chain, including product distribution, payment infrastructure, and logistics services. In doing so, regulators are signaling a clear policy shift toward more active and structured oversight of digital market dynamics.
Expanded Scope of Anti-Competitive Conduct
The guidelines introduce a comprehensive analytical framework covering both price-related and non-price-related conduct, reflecting a more nuanced approach to assessing competitive harm in platform-driven markets.
Price-Related Conduct
Regulators have identified several pricing practices that may constitute anti-competitive behavior, particularly where platforms hold a position of market power. These include:
✓ Predatory pricing strategies designed to exclude competitors
✓ Resale price maintenance arrangements
✓ Price parity clauses restricting sellers from offering better terms on alternative channels
✓ Platform-imposed fees (e.g., commissions, advertising charges, logistics and payment processing fees) where such fees are excessive, discriminatory, or lack objective justification
This approach reflects an increased emphasis on transparency, proportionality, and fairness in platform pricing structures, particularly in relation to dependent business users.
Non-Price Conduct and Platform Governance
The guidelines also impose restrictions on a broad range of non-price practices that may distort competition within digital ecosystems. Key areas of focus include:
✓ Self-preferencing: preferential treatment of a platform’s own products or services
✓ Algorithmic bias: manipulation of search rankings or product visibility to disadvantage competitors
✓ Tying and bundling practices: requiring the use of in-house services (e.g., logistics or payment systems) as a condition of platform access
✓ Unjustified delisting or refusal to deal: restricting market access for business users without objective justification
Importantly, the framework explicitly recognizes the role of data and algorithms as potential sources of competitive advantage. The use of platform-generated data to favor proprietary services or create discriminatory outcomes is likely to attract heightened regulatory scrutiny.
Broad Enforcement Approach and Legal Consequences
The guidelines adopt a principles-based enforcement model, extending beyond specifically enumerated conduct to capture any behavior that may result in market distortion or confer an unfair competitive advantage. This provides regulators with significant discretion in assessing evolving digital business models.
While the guidelines themselves do not introduce standalone penalties, non-compliance falls within the scope of the Trade Competition Act. As such, violations may give rise to both administrative and criminal sanctions, particularly in cases involving abuse of dominant position or anti-competitive agreements.
Strategic Implications for Businesses
From a legal and policy standpoint, these developments represent a decisive step toward aligning Thailand’s competition framework with global trends in digital market regulation. Authorities are increasingly adopting more sophisticated tools to assess platform behavior, particularly in relation to data usage, ecosystem control, and indirect forms of market power.
For businesses—especially platform operators—the implications are material:
✓ Reassessment of commercial models: Pricing structures, fee arrangements, and platform policies should be reviewed to ensure they are transparent, justifiable, and non-discriminatory
✓ Governance of algorithms and data: Increased scrutiny over how data is collected, processed, and deployed within platform ecosystems
✓ Strengthening compliance frameworks: Implementation of internal competition law controls, particularly in relation to platform design and operational decision-making
✓ Risk management and documentation: Maintaining clear justifications for pricing, ranking, and access decisions to mitigate enforcement risk
Key Takeaways
✓ Regulatory focus is shifting toward digital ecosystems: Multi-sided platforms are now a central focus of competition enforcement in Thailand
✓ Non-price conduct is under heightened scrutiny: Algorithmic practices, data usage, and platform governance are key enforcement priorities
✓ Principles-based enforcement increases regulatory discretion: Businesses must assess not only explicit prohibitions but also broader competitive effects
✓ Alignment with global regulatory trends: Thailand is moving closer to EU and other international models in addressing platform dominance
✓ Proactive compliance is essential: Early alignment of business practices with evolving standards will be critical to mitigating legal and reputational risk
