GIR: Practitioner’s Guide to Global Investigations, 10th Edition – Thailand

Recent high-profile corporate fraud and accounting scandals have brought increased scrutiny to governance, compliance, and enforcement practices in Thailand, highlighting the legal and practical challenges facing companies operating in the country. As regulators and law enforcement authorities sharpen their focus on financial misconduct, cybercrime, and corruption, businesses must navigate a complex and evolving investigative landscape.

Tilleke & Gibbins’ investigations and compliance team examines these issues in the Thailand chapter of The Practitioner’s Guide to Global Investigations – Tenth Edition, published by Global Investigations Review (GIR). The chapter provides a detailed overview of Thailand’s legal framework for corporate investigations, offering practical guidance for companies and counsel responding to regulatory and criminal scrutiny.

The Thailand chapter covers key topics including corporate criminal liability, enforcement priorities, internal investigations, data protection considerations, dawn raids, whistleblowing, cyber-related investigations, and cross-border cooperation. It also addresses emerging issues such as cybersecurity enforcement, economic sanctions compliance, and anticipated developments affecting investigations in Thailand.

The chapter is authored by John Frangos, Chitchai Punsan, Alongkorn Tongmee, Michael Ramirez, Piyawat Vitooraporn, and Michelle McLeod. The Thailand chapter is available as a PDF below, and the full guide can be accessed on the GIR website.

Thailand’s Office of the Prime Minister has issued a new regulation titled Giving or Receiving Gifts of State Officials B.E. 2565 (2022). This regulation, which took effect on January 13, 2023, repeals the previous 2001 version and updates certain provisions to be in sync with Thailand’s primary anticorruption law, the Organic Act on Anti-Corruption B.E. 2561 (2018). The regulation prohibits state officials’ family members from receiving gifts from people who are dealing with the officials’ respective agencies. It also prohibits state officials from giving gifts to their supervisors and their supervisors’ family members. An exception, carried over from the previous version of the regulation, is provided for gifts on limited “customary occasions” valued at THB 3,000 or less. There are some notable revisions in the definitions of the new regulation. The term “gift” is now clearly defined to include “training” or “seminars.” In addition, the term “family members” now includes spouses living together “as husband and wife,” even if not legally married. For example, the common-law spouse of an officer considering a license application is not allowed to receive a gift from or attend an overseas seminar organized by the applicant. The regulation also provides: Guidelines for state officials to self-report in case of violation by a family member; Instructions on how to deal with the gifts received in violation; and Disciplinary actions for violation. Importantly, the regulation continues to prohibit the receipt of gifts by state officials’ family members but does not expressly criminalize the giving of gifts by private parties. However, all who deal with government officials should take note of the updated regulation to avoid creating a situation that might violate the rules.

On October 31, 2022, the Department of Trade in Myanmar’s Ministry of Commerce announced that payments for importation at the border are to be made via bank transaction. This announcement comes into force with Import/Export Newsletter No. 10/2022, dated October 31, 2022, issued by the Department of Trade, with the purpose of implementing a systematic payment system for import and export at the border, in accordance with a suggestion made by the Financial Action Task Force (FATF), an international financial watchdog. (This follows the recent news that the FATF has blacklisted Myanmar.) This requirement means that only bank transactions will be accepted for import payments in the border trade. Initially, this system will be applied to trade at the Myanmar-Thailand border only. The new requirement to pay for imports only via bank transaction states that export earnings and other types of foreign currency earnings (including salary and income remitted by Myanmar workers overseas) will be allowed to be used for imports. Importers are required to make the payments for import goods—using these earnings—via their banks. That is, Importers operating in the border trade must have foreign currency earnings received through official banking channels and must make import payments abroad through official banking channels using those earnings. In contrast to previous practices, they are unable to use other sources of income and are not able to make other payment arrangements that do not involve bank transactions. The procedures for importation at the Myanmar-Thailand border are as follows: Companies applying to the Department of Trade for an import license must produce credit advice and original bank statements that prove the receipt of export earnings or other earnings into their bank account. The Department of Trade will scrutinize the reported export earnings or other earnings, and approve the import license for an

As Thailand has paid more and closer attention to anticorruption issues, a number of measures have been introduced and implemented over the years, including the establishment of the Complaint Center for Foreign Investors (CCFI) in 2015. The CCFI was set up by the Office of Public Sector Anti-Corruption Commission (PACC) to promote transparency and integrity in the Thai public sector and enhance the confidence of foreign investors conducting business in Thailand. Though the CCFI has been in operation for many years, many foreign investors conducting business in Thailand have either remained unaware of it or have been reluctant to use it because of concerns that acting against Thai public officials could cause problems for their businesses or in their personal lives. However, recently the PACC has made a renewed push to promote the CCFI as a suitable channel for foreign investors to lodge complaints when they face unfair services or treatment, or face requests for benefits from Thai public officials. Lodging a Complaint with the CCFI The CCFI was established to administer the PACC’s responsibilities under Section 58/2 of the Executive Measures in Anti-Corruption Act B.E. 2551 (2008), which authorizes the PACC to notify the superior of any state agency appearing to have regulations or procedures that fail to comply with the Licensing Facilitation Act; are deemed by the PACC to cause a nuisance or damages to a public service clientele; or cause severe detriment to a government service. Practically, this means that when investors have a complaint that fits the scope described in the law, they can contact the CCFI, which will take action by getting the relevant agency or government authority to examine the issue. In cases concerning agency regulations and procedures, this will be the head of the relevant agency, but if the circumstances indicate malpractice

As many countries have experienced firsthand, corruption and bribery can have severe and far-reaching effects throughout a country’s political and economic systems. They not only impact the financial status and administrative ability of the countries involved, but at the same time, can also create and perpetuate a negative image of those countries to current or potential trade or investment partners. Recognizing the importance of minimizing or eliminating the damaging effects of bribery and corruption, many countries have made—and continue to make—efforts to strengthen their anticorruption and antibribery capabilities. Thailand has enacted relevant laws and enforced anticorruption measures in both the public and private sectors. Under Thai law, a bribe can take the form of property or a benefit. “Property” can be tangible (such as money, a car, a house, etc.) or intangible (such as copyrights, patents, etc.), while a “benefit” can be a gift, a discount, entertainment, healthcare costs, a job promotion, and so on. This article discusses the key provisions related to criminal offenses committed by private parties under three anticorruption laws in Thailand: Organic Act on Anti-Corruption B.E. 2561 (2018) Public Procurement and Supplies Administration Act, B.E. 2560 (2017) Act on Offenses Relating to the Submission of Bids to State Agencies B.E. 2542 (1999) Organic Act on Anti-Corruption The key provision of the Organic Act on Anti-Corruption (OAAC) is Section 176, which prohibits giving, offering, or promising property or a benefit to a public official, foreign public official, or official of a public international organization with the intent to induce the official to wrongfully perform his or her duty. Violations are subject to criminal liability, punishable by imprisonment for up to five years, a fine of up to THB 100,000 (approx. USD 3,000), or both. If the offender is a person associated with a company that does
