OVERVIEW

Strategic competition guidance across Southeast Asia.

Tilleke & Gibbins’ Antitrust & Competition practice delivers practical, business-focused guidance to companies operating across a rapidly evolving competition law landscape. We advise on both behavioral controls—including abuse of dominance, cartel conduct, and unfair trade practices—and structural controls, particularly merger control and notification requirements.

As competition regimes across Southeast Asia continue to mature and converge, we assist clients in navigating a broad spectrum of competition law issues. Our work includes multi-jurisdictional merger control analysis and filings for cross-border and domestic M&A transactions, competition assessments for trade and distribution contracts, defense strategy against investigations and claims, and consultation on sale and marketing campaigns, sector-specific regulations, and emerging digital platform frameworks. We develop commercially pragmatic legal and commercial strategies that facilitate trade, commerce, and investment while maintaining full compliance with applicable competition laws.

A key strength of our practice is our close collaboration with select international and domestic economic consulting firms. For complex matters, we deliver integrated legal and economic analysis covering market definition, competitive effects, damages assessment, and merger filing support.

We also provide tailored competition law training programs, including compliance training and dawn raid preparedness, to help in‑house teams mitigate regulatory risk and respond effectively to enforcement action.

On February 4, 2026, the Trade Competition Commission of Thailand (TCCT) released a draft notification outlining updated criteria and procedures for requesting advance decisions under section 59 of the Trade Competition Act (TCA). This draft is now open for public comment through the TCCT website until March 5, 2026. Section 59 of the TCA lets businesses proactively ask the TCCT to review whether a planned activity, such as a business strategy, marketing program, or other proposed conduct, could potentially violate the TCA. The major limitation is that this mechanism cannot be used for merger‑control matters. The new draft aims to make the process more accessible and user‑friendly. Key updates include allowing for electronic submission of requests and establishing a shorter notification timeframe, requiring the TCCT to explain any delay to the 60‑day review period within 7 days instead of the previous 15 days. For many businesses, this preliminary consultation tool is an effective way to reduce regulatory and competition‑law risks. Businesses that have taken advantage of this process have found that obtaining an advance decision can provide meaningful legal certainty, as the decision is binding once issued.

Spurred by global geopolitics and Canada’s Indo-Pacific Strategy, which aims to forge deeper ties with ASEAN, Canadian companies have been showing growing interest in Thailand and Southeast Asia in recent years. To understand the opportunities offered by the region, we sat down with Andrew Stoutley, a Toronto native and the chief operating officer of Tilleke & Gibbins, a leading Southeast Asian regional law firm with over 130 years of history in Thailand. Q: Why are Canadian companies looking at Thailand and Southeast Asia right now? A: Two reasons stand out. First, diversification has moved up the agenda. Many Canadian companies want options outside North America due to tariff volatility and policy uncertainty in the United States, as well as questions around the next Canada–United States–Mexico Agreement mandatory joint review. At the same time, the shift of global production from China to Southeast Asia is accelerating, driven by rising costs, geopolitics, and the need to avoid overreliance on a single market. As a result, Canadian companies are looking for a second production base or a regional hub, and Thailand and its neighbors are natural choices given their manufacturing depth, location, and established supply chains. Second, Canada’s own efforts in the region are gaining traction. The Indo-Pacific Strategy has led to more on-the-ground support, including larger trade missions, upgraded diplomatic posts, and new financing options. Export Development Canada (EDC) now has a presence in Bangkok, giving Canadian companies a direct line to financing and insurance in Thailand. There’s also steady progress on trade frameworks like the recently signed Canada–Indonesia Comprehensive Economic Partnership Agreement (which will come into effect pending domestic procedures), ongoing negotiations of a Canada–ASEAN FTA, and the exciting announcement about the launch of negotiations of a Canada–Thailand FTA. Together, these developments have the potential to make it much easier

Thailand has expanded the circumstances under which state agencies may bypass competitive bidding procedures to address urgent security challenges. On November 28, 2025, Thailand’s Ministry of Finance published the Ministerial Regulation Determining Cases of Procurement by Specific Method (No. 6) B.E. 2568 in the Royal Gazette, introducing a new pathway for procuring supplies and services needed to address cyber and military threats that may affect the stability of government agencies or the nation. For technology vendors, cybersecurity firms, and defense contractors, this regulatory change creates immediate opportunities to engage directly with government buyers facing urgent security challenges. New Fast-Track Category for Security Threats The regulation amends Thailand’s Public Procurement and Supplies Management Act B.E. 2560 (2017) to add a new category of procurement that qualifies for the “specific method”—a noncompetitive, direct selection process. Previously, agencies could use this expedited method only in limited circumstances, such as emergencies, cases with proprietary technology requirements, or national security operations. The new provision explicitly covers procurement of supplies related to preventing or resolving cyber or military threats that could impact the stability of a state agency or the country. This addition recognizes the urgent nature of modern security challenges, where competitive bidding timelines may leave agencies vulnerable during critical threat windows. State agencies dealing with active cyberattacks, preparing defensive measures against anticipated threats, or responding to military security concerns can now move directly to negotiate with qualified vendors rather than conducting lengthy public tender processes. Vendor Considerations Vendors offering cybersecurity solutions now have a regulatory avenue to work directly with government clients when stability concerns are present. These solutions include threat detection systems, anti-ransomware tools, incident response services, firewalls, and security consulting. Similarly, defense contractors providing military equipment or specialized security supplies can pursue direct engagement channels where traditional procurement methods would create

Thailand currently lacks a specific franchise act. Consequently, the legality of any franchise agreement is determined by its compliance with various existing laws, such as the Civil and Commercial Code, the Trademark Act B.E. 2534 (1991) (as amended), and the Unfair Contract Terms Act B.E. 2530 (1997). Thailand is a freedom-to-contract jurisdiction. This allows for a high degree of flexibility and autonomy in contractual arrangements, provided that the terms do not violate any laws or public policy and do not fall under the scope of unfair contract terms. Given this, the requirement for fairness in franchise agreement terms often leads to uncertainty, but decisions from the Trade Competition Commission of Thailand (TCCT) can provide guidance on whether specific contentious terms are in fact fair.  One issue worth examining in this light is the inclusion of terms on nonrefundable franchise fees and strict purchasing conditions. Franchise Fee: Unfair to Refuse Refund? Nonrefundable franchise fees represent a significant upfront investment for franchisees, often becoming a point of contention if the franchise relationship deteriorates or the franchisor ceases operations. Their fairness and enforceability are frequently scrutinized by regulatory bodies like the TCCT, highlighting the critical balance between contractual freedom and franchisee protection. Faced with one such case, the TCCT considered whether it was unfair for the franchisor to refuse to refund the franchise fee after the franchisor ceased operations.  The franchisee had entered into a service agreement on August 2, 2021, and begun operating on October 9, 2021. However, by November 21, 2023, the franchisee was notified that the system would be shut down for maintenance, and by December 26, 2023, the franchisor announced the cessation of operations due to financial losses. The franchisee then requested a refund of the franchise fee. Unfortunately for the franchisee, the TCCT found that the franchisor’s
