On March 31, 2026, Vietnam’s government issued Decree 102/2026/ND-CP (Decree 102), which amends Decree 75/2019/ND-CP on administrative sanctions for competition law violations (Decree 75). Effective from May 20, 2026, the new decree introduces a number of significant changes aimed at strengthening enforcement, revising penalty structures, and broadening the range of remedial measures, primarily for violations related to economic concentration. Revised Penalties for Economic Concentration Violations Decree 102 significantly revises the penalties for violations related to economic concentration. Failure to notify an economic concentration; implementing an economic concentration before clearance Under the new framework, Articles 14 and 15 of Decree 75 have been amended to impose a range of monetary fines, rather than relying solely on percentage‑based penalties as under the previous regime, for violations involving the failure to notify an economic concentration or the implementation of an economic concentration prior to clearance. The fines range from VND 500 million to VND 1 billion for each enterprise participating in a concentration with combined assets, revenues, or purchase value below VND 3,000 billion in the preceding fiscal year, capped at 5% of the violating enterprise’s total turnover in the relevant market. For concentrations meeting or exceeding the VND 3,000 billion threshold across those same metrics, the fines increase to VND 1 billion to VND 2 billion per enterprise, also subject to the 5% cap. These differentiated thresholds allow penalties to better reflect the size of the transaction and its potential competitive impact. Non-compliance with conditional approvals Enterprises that do not implement or only partially implement the conditions specified in a conditional economic concentration approval decision face fines ranging from 1% to 3% of total turnover in the relevant market during the fiscal year preceding the violation. Decree 102 also adds a new remedial measure requiring enterprises to fully implement all conditions

Following Thailand’s recent expansion of the “major shareholder” definition for securities and digital asset businesses, the Securities and Exchange Commission (SEC) launched a public hearing on April 7, 2026, on expanding the major shareholder definition further to cover funding sources behind share acquisitions in licensed securities and digital asset business operators. The public hearing will remain open for 15 days from the launch date, after which the proposed expansion is expected to take effect promptly so that operators can comply with both the earlier and additional requirements within the 180-day transitional period under the earlier regulations. Funding Sources Captured Under Control-Based Test Under the draft rules, persons who fund direct or indirect major shareholders’ acquisition of shares in a licensed operator would be deemed “controlling persons” and subject to SEC approval as major shareholders. This extends beyond traditional lenders to include guarantors, counterparties to derivatives or structured products, and any arrangement that results in a person being, directly or indirectly, a source of funding to a major shareholder. The SEC proposes to exempt three categories of funding arrangements from approval: Loans from Thai licensed financial institutions or BCBS (Basel Committee on Banking Supervision)-jurisdiction foreign banks; Margin loans for securities trading under Thai securities law; and Repurchase agreements under Thai securities law. Exemptions for Funding Sources of Government-Linked Entities The consultation proposes to stop look-through beyond the level of certain government-linked shareholders, including, without limitation, ministries, departments, bureaus, public organizations, independent agencies, and certain state enterprises. The SEC reasons that these entities’ mandates, duties, and funding sources are already subject to government oversight and audit, presenting minimal ownership-structure risk. Practical Implications Licensed securities and digital asset business operators should begin mapping their funding chains under the expanded definition in preparation for filing approval applications for any newly captured funding providers

Thailand has introduced new regulatory guidance requiring digital platform operators to adopt structured, transparent, and fair fee practices. On March 16, 2026, the Electronic Transactions Development Agency (ETDA) published Announcement No. DPS 2/2569, titled “Guidelines for Transparency and Fairness in Digital Platform Service Fee Determination,” issued under the Royal Decree on Digital Platform Service Business Operations B.E. 2565 (2022). The guidelines establish a framework governing how digital platform operators should set, disclose, and adjust fees charged to users and related service providers such as logistics and payment providers. Although framed as best-practice guidance rather than legally binding rules with explicit penalties, the guidelines carry regulatory weight under the royal decree and represent a significant step toward structured governance of digital platform fee practices in Thailand. The guidelines establish various transparency principles and divide fees into two distinct categories—compulsory and additional—with specific governance principles for each. Transparency Principles The guidelines recommend that digital platform operators adopt several transparency measures to ensure that users can fully understand the costs of using a platform. Fee catalog. All fees should be consolidated into a single, accessible location, which should include the fee name, definition, scope of covered services, calculation methodology, rate, billing period, and calculation examples. Minimum service disclosure. Operators should disclose the minimum service that users can expect, such as baseline visibility, product listing capabilities, access to transaction data, and back-end dashboard access. Price structure disclosure. Operators should disclose the categories of costs underlying their fees, such as system maintenance, cybersecurity, and operational costs. While exact cost figures need not be made public, operators should be able to provide numerical data to regulators upon request. Clear fee formulas. Fee calculations should be simple and easy to understand—for example, percentage of net sales, cost per order, or cost per product listing. Operators should

As digital commerce continues to reshape consumer behavior in Thailand, the Office of the Consumer Protection Board (OCPB) has been taking steps to review and update key regulations for online platforms. The OCPB has had a particular focus on addressing the risks posed by e-marketplace businesses—from misleading product information to fraudulent online transactions. Some of the regulator’s current legislative efforts related to Thailand’s labeling regulations as well as potential changes to the country’s law on direct sales and marketing. Proposed Changes to Consumer Protection Labeling Regulations On February 24, 2026, the OCPB convened a public hearing to review the Notification of the Committee on Labels re: Specification of Goods as Controlled Label Goods B.E. 2565 (2022) and its annex issued under the Consumer Protection Act. The closed-door session, which started the OPCD’s process of seeking feedback on the proposed changes, brought together representatives from government agencies, business operators, and consumer groups. The OCPB explained that its review of the labeling regulations aims to address regulatory gaps arising from evolving commercial practices, particularly the expansion of e-commerce and cross-border transactions. Authorities highlighted recurring issues involving product information that is unclear, incomplete, or potentially misleading in digital sales channels. The proposed revisions are intended to improve consumers’ access to accurate and complete product information, ensure that label disclosures remain relevant amid the growth of e-commerce, and strengthen protections against deceptive or misleading digital advertising. The review is being undertaken pursuant to the Consumer Protection Act B.E. 2522 (1979). As part of the initiative, the OCPB signaled a potential update to the categories of “controlled label products” as well as enhanced disclosure obligations for business operators, with the broader aim of promoting greater transparency, reinforcing operator accountability, and aligning Thailand’s labeling framework with current market conditions. The OCPB secretary general emphasized that
