Thailand has liberalized its wine import regime, allowing, for the first time, multiple importers to bring in and distribute the same wine brands. On March 27, 2026, the Ministry of Finance issued the Ministerial Regulation on the Importation of Alcoholic Beverages (No. 3) 2026, which waives the requirement to appoint a sole authorized agent for alcoholic beverages to be specified in notifications from the Excise Department. The Excise Department has already issued its first such notification, expressly exempting wine and sparkling wine made from grapes from the sole agent requirement. For all other types of alcoholic beverages (e.g., beer, tequila, spirits) the sole agent requirement remains in force, and applicants for importer licenses must provide evidence of exclusive distributorship issued by the manufacturer or brand owner. The exemption may be extended to other alcoholic beverage categories through future Excise Department notifications. Implications for Competition and Tourism The reform allows multiple importers to bring in and distribute the same wine brand without routing through the brand owner’s designated exclusive importer, reducing monopolization and boosting competition. Excise Department Director-General Pornchai Thirawet noted that wine was chosen as the starting point because implementation is straightforward in this case and because domestic wine prices remain high—with increased competition expected to exert downward pressure on prices. More broadly, the reform is intended to lower market entry barriers, expand supply, and make wine more accessible to Thai consumers, while supporting Thailand’s position as a regional tourism hub. Product Quality Control and Loss of Sole Agent Accountability Under the previous framework, the designated importer bore full responsibility for the proper storage, handling, and distribution of wine and sparkling wine from importation to final sale. This arrangement helped ensure that products were maintained under appropriate conditions, including temperature control, light exposure, and humidity management, to preserve quality

Effective June 22, 2026, Thai Industrial Standards (TIS) for food contact paper and cooking paper will be enforced as mandatory for sale in the Thai market. This move has important implications for product licensing and tightens hygiene, labeling, and chemical-safety requirements for food-contact and cooking paper products. Thailand is strengthening its regulatory framework for paper-based culinary materials against a backdrop of accelerating global commitments to ESG and sustainability, as such materials—particularly those derived from natural or recycled fibers—have emerged as key alternatives to plastics in food preparation, cooking, and packaging applications. As a result, regulators worldwide are tightening controls to ensure that sustainability initiatives do not compromise consumer safety, particularly regarding the potential migration of chemical substances into food. Regulatory Framework: Voluntary vs. Mandatory Standards Standards under the TIS regime are generally classified into two categories. Voluntary standards allow manufacturers or importers to apply for a product license and affix the TIS mark to demonstrate product quality and build consumer confidence, but compliance is not legally required. Mandatory standards, by contrast, require manufacturers and importers to obtain a product license and affix the TIS mark before placing products on the Thai market, and noncompliant products cannot be legally sold. Previously, the TIS standards for food contact paper (TIS 2948-2562) and cooking paper (TIS 3438-2022) fell under the voluntary standard regime, meaning that obtaining a TIS license and displaying the TIS mark was optional. However, due to the increasing use of paper in food preparation and cooking, the Thai Industrial Standards Institute has determined that upgrading these standards to mandatory status is necessary to enhance consumer safety. As a result, all paper intended for food contact or cooking purposes must now obtain a TIS product license prior to sale in Thailand. Scope of the Standards The primary distinction between the

Vietnam has progressively positioned blockchain as a strategic technology within its broader digital transformation agenda over the past decade. From early policy orientations to more recent legislative developments, the regulatory approach has gradually shifted from high-level recognition to more concrete legal integration. Against this backdrop, a new draft decree regulating activities relating to product and goods identification, authentication, and traceability (the “Draft Decree”) marks a notable turning point. Rather than merely referencing blockchain as a policy priority, the Draft Decree incorporates blockchain directly into a nationwide regulatory system, positioning it as part of the underlying infrastructure for data governance and public administration in relation to the management, verification, and traceability of product-related data. Evolution of Vietnam’s Blockchain Legal Framework: The Draft Decree in Context Vietnam’s blockchain legal framework has developed in several distinct phases. The first phase, beginning around 2019, was characterized by high-level policy recognition in several resolutions of the Party Central Committee. Particularly, blockchain was identified as part of the broader category of digital technologies critical to industrial modernization and participation in the Fourth Industrial Revolution. These resolutions did not regulate blockchain directly, but established its strategic importance at the national level. The second phase (2023 to 2025) saw the introduction of national strategies and technology policies that more explicitly recognized blockchain as a priority technology. Those policies collectively signaled a clear policy commitment to developing blockchain infrastructure and applications. However, these instruments remained largely at a policy-level and did not establish binding regulatory frameworks. The third phase (from 2025) involves the gradual integration of blockchain into sectoral legislation. Laws such as the Law on Digital Technology Industry (2025), the Law on Personal Data Protection (2025), and the Law on Science, Technology, and Innovation (2025) have introduced concepts such as digital assets, crypto assets, and even specific

Thailand’s Board of Investment (BOI) has introduced a new investment promotion measure to encourage partnerships between Thai and foreign automotive parts manufacturers. The measure, published in the Government Gazette on March 31, 2026, under Notification of the Board of Investment No. 5/2569 Re: Investment Promotion Measures for Joint Ventures between Thai and Foreign Companies in the Auto Parts Manufacturing Industry, aims to enhance local industry participation and create new business opportunities for Thai operators. Corporate Income Tax Exemption Under this measure, the BOI grants an additional corporate income tax (CIT) exemption of three years to both new investment projects and existing operators under the BOI’s business category 3.4 (manufacture of engines, equipment, or parts) or category 3.5 (manufacture of vehicle parts). If the CIT exemption period is added to an existing one, the total exemption period will be capped at a maximum of eight years. To benefit from the exemption, certain conditions must be met, as described below. Conditions for New Investment Projects The joint venture company must be newly established after January 15, 2026. At least 20% of the registered capital must be held by a Thai juristic person throughout the CIT exemption period. The Thai juristic person must have been operating in the automotive or auto parts industry for at least three years prior to the application date and must be at least 60%-owned by Thai individuals. Conditions for Existing BOI-Promoted Projects The company must have been wholly foreign-owned at the time the promotion certificate was issued. The shareholding structure must be amended following the issuance of the notification to establish a joint venture between a foreign juristic person and a Thai juristic person that has been operating in the automotive or auto parts industry for at least three years prior to the application date. This Thai
