Over the past several years, numerous automobile manufacturers have brought electric vehicles (EVs) to the market and received positive feedback from consumers in Thailand and around the world. EVs have gained popularity due to their lower maintenance costs, reduced energy expenses, and environmental benefits. However, reports have emerged of EVs causing problems such as battery fires, autopilot malfunctions leading to accidents, and safety systems such as brakes engaging automatically under inappropriate conditions. Even when these situations do not cause injury to drivers or passengers, they raise significant concerns for EV manufacturers, importers, and sellers operating in Thailand. These problems may seriously impact businesses if the products are identified as unsafe under Thailand’s Product Liability Act (PLA), officially known as the Liability for Damages Arising from Unsafe Products Act. Under this law, authorities or courts can order business operators to recall products from the market or prohibit their export, import, or sale. To manage and mitigate the risk of being found liable for damages due to an unsafe product under the PLA, EV business operators should be aware of the scope of the law. Potentially Liable Parties The PLA identifies several types of entrepreneurs and business operators—both individuals and entities—as “potentially liable parties” (PLPs) who may be held liable under the law. In the EV context, this could include vehicle manufacturers, battery suppliers, software developers whose systems are integrated into the vehicle, and local importers or distributors. Specifically, the PLA covers: Manufacturers or hirers Importers Sellers of goods for which the manufacturer, hirer, or importer cannot be identified Any other party who uses the name, trade name, trademark, or statements associated with the alleged unsafe products, or acts in a manner that causes them to be perceived as a manufacturer, hirer, or importer Definition of “Product” and “Unsafe Product” The

Thailand’s Securities and Exchange Commission (SEC) has filed a criminal complaint against a licensed digital asset broker, its overseas trading platform, and its executives for allegedly operating an unlicensed digital asset exchange targeting Thai customers. The case marks an escalation in the SEC’s enforcement efforts against unlicensed offshore platforms that attempt to serve Thai users through local licensed entities. Criminal Complaint On February 20, 2026, the SEC filed a criminal complaint with the Economic Crime Suppression Division against a local licensed digital asset broker, its overseas global trading platform, and its executives. The SEC alleges that the parties violated the Digital Asset Business Emergency Decree B.E. 2561 (2018) by cooperatively operating a digital asset exchange business on a cross-border basis since 2023 without the required SEC license. According to the SEC, the local broker promoted the overseas platform’s services to the public through Thai-language posts on social media channels, with services available exclusively to customers residing in Thailand. Access to the global platform was provided through the local broker’s website and mobile application. Customers who registered for the local broker’s services were automatically granted access to the global platform without having to undergo a separate identity verification process. The SEC also found that the local broker provided back-office system support services to the global platform. The SEC considers these activities to constitute joint operation of an unlicensed digital asset exchange. The former executives of the local broker are being held liable as the responsible persons during the relevant period. The SEC emphasized that the complaint initiates the criminal process, and the decision to prosecute or convict the accused parties will ultimately be made by law enforcement authorities and the criminal courts. Platform Blocking The SEC has also coordinated with the Ministry of Digital Economy and Society to block public

The Bank of Thailand (BOT) has officially implemented a new regulatory framework supervising systemically important retail payment systems (SIRPS), effective February 21, 2026, with PromptPay being the first payment system designated as a SIRPS. Under this new set of regulations, the BOT may designate payment systems under the Payment Systems Act B.E. 2560 (2017) as SIRPSs based on quantitative and qualitative assessments. Once a system is designated as a SIRPS, the operator becomes subject to expanded supervisory obligations beyond the general requirements of the Payment Systems Act. Enhanced Supervisory Requirements SIRPS operators must comply with a heightened supervisory regime across three key areas, outlined below. 1. Governance SIRPS operators must maintain robust and transparent governance structures, including: Balanced board composition, with at least one-third of the board comprising independent directors who represent stakeholders in the system (such as payment service providers, consumers, and experts). Independent directors may serve for no more than two consecutive terms. Subcommittees to assist the board in overseeing compliance, policy implementation, and operational strategy. Clear separation between executives responsible for risk and information security and those overseeing day-to-day business operations. Risk Management and System SecuritySIRPS operators must implement comprehensive risk management frameworks, including: Clear service agreements between the SIRPS operator and its direct participants (payment service providers who connect directly to the SIRPS), defining roles and responsibilities among stakeholders. These agreements must include obligations for direct SIRPS participants to supervise any indirect participants they onboard to ensure compliance with service agreements and business rules. A business continuity plan covering both IT and non-IT aspects, with annual review. The SIRPS must target service availability comparable to international payment infrastructures, including the ability to recover operations within two hours of a disruption and to maintain scalable operational capacity. Tools and controls to monitor and manage material or

Laos’ Food and Drug Department (FDD) has been using a new online registration system for drugs since the beginning of the year. The system, which was implemented following the November 2025 issuance of Notice No. 5960/FDD, became the official pathway for submissions on January 1, 2026. Since that date, paper-based registrations have no longer been accepted. This marks a significant advancement in the digitalization of regulatory processes in Laos. As the online system is now the exclusive platform for registration, renewal, and amendments, companies that have not yet aligned their processes to the new system should act promptly to ensure a smooth transition. To assist with this, the FDD will conduct periodic training sessions on the use of the online registration system, which will be delivered either in person or remotely, depending on operator demand. To start using the system, drug and medical device manufacturers, as well as import-export companies, that have not yet registered must submit a formal request identifying the authorized personnel who will access the platform, after which they will be issued user accounts and access codes. Each request must be accompanied by the company’s enterprise registration certificate (incorporation certificate), a copy of the identity card or passport of each designated user, and a scanned copy of their signature. There is no restriction on the number of users per company, allowing flexibility to meet operational needs. Companies that already hold accounts and access codes from the trial phase may continue using them and may apply for additional accounts if needed. Additional Requirements The new system also introduces a standardized format for drug registration numbers. For example, an import drug registration number such as 06 I 4040/15 will be changed to 06-IM-04040-15, and a domestic drug registration number such as 06 L 4040/15 will be changed to
