Business Ownership Under the Thai–U.S. Treaty of Amity
American citizens and qualifying American-owned companies may enjoy special business ownership rights in Thailand under the Treaty of Amity and Economic Relations between the Kingdom of Thailand and the United States of America, signed in 1966 and entering into force in 1968.
Under this treaty, eligible American nationals may establish and own up to 100% of the shares in certain businesses operating in Thailand.
This provides an important advantage for American investors who wish to establish a business in Thailand without relying on Thai majority shareholders.
However, the treaty does not apply to every business activity, and applicants must meet specific eligibility and registration requirements.
1. Business Ownership Rights Under the Treaty of Amity
The Thai–U.S. Treaty of Amity provides qualifying American individuals and companies with certain protections when conducting business in Thailand.
One of its principal benefits is the ability to establish a company with up to 100% American ownership in business sectors covered by the treaty.
For eligible treaty-protected activities, American-owned businesses may obtain the relevant Foreign Business Certificate rather than applying for an ordinary Foreign Business License (FBL).
This arrangement is subject to compliance with the applicable Thai laws and administrative requirements.
2. Who Is Eligible for Protection Under the Treaty?
The treaty provides protection to qualifying American individuals and legal entities.
2.1 American Citizens
Individuals holding United States citizenship may qualify for protection under the treaty when conducting eligible business activities in Thailand.
2.2 American-Owned Legal Entities
A legal entity may qualify for treaty protection when it meets the following requirements:
1. Company Registration
The legal entity must be established under the laws of Thailand or the United States of America.
2. Majority American Ownership
The majority of the company’s capital must be owned by American nationals or qualifying American entities.
3. Board of Directors
More than half of the company’s directors must be American and/or Thai nationals.
4. Authorized Signatory
If only one director is authorized to sign on behalf of the company, that director must not be a national of a third country.
5. Multiple Authorized Signatories
If several directors are jointly authorized to sign on behalf of the company, the majority of those authorized directors must not be nationals of third countries.
6. American Corporate Shareholders
Where the majority shareholder is an American company, the nationality of the directors and relevant ownership structure of that American company must also be considered when determining eligibility.
3. Businesses Excluded from Treaty Protection
Although the Treaty of Amity provides significant business ownership privileges, certain business activities are excluded from its protections.
American individuals and legal entities cannot rely on the treaty’s preferential treatment for the following reserved activities:
3.1 Communications
Certain communications-related business activities are excluded from treaty protection.
3.2 Transportation
Transportation and transport-related business activities are excluded from the treaty’s preferential treatment.
3.3 Fiduciary Functions
Business activities involving fiduciary responsibilities, including managing property or assets for the benefit of others, are excluded.
3.4 Banking Involving Depository Functions
Banking activities involving the acceptance of deposits are excluded from treaty protection.
3.5 Exploitation of Land and Natural Resources
Activities involving the exploitation of land or other natural resources are excluded.
3.6 Domestic Trade in Indigenous Agricultural Products
Domestic trading activities involving indigenous agricultural products are also excluded from the treaty’s preferential treatment.
4. Business Activities Not Covered by the Treaty
American individuals or companies wishing to engage in reserved business activities must comply with the Foreign Business Act B.E. 2542 (1999), as applicable to other foreign nationals.
Treaty protection does not automatically authorize American investors to conduct businesses excluded from the agreement.
Before establishing a company, investors should review whether their proposed activities qualify for treaty protection.
5. Applying for Protection Under the Thai–U.S. Treaty of Amity
American individuals and qualifying companies wishing to conduct business under the treaty must follow the relevant certification and registration procedures.
Step 1: Request Certification from the U.S. Embassy
The applicant must request an official certification letter from the United States Embassy in Thailand.
The letter confirms that the applicant is an American individual or qualifying legal entity eligible to seek protection under the Treaty of Amity.
Step 2: Certification to the Department of Business Development
The certification is addressed to the Department of Business Development (DBD), Ministry of Commerce of Thailand.
The documentation identifies the applicant and confirms the intention to conduct business in Thailand under treaty protection.
Step 3: Submit the Relevant Business Application
After obtaining the necessary nationality certification, the applicant must proceed with the relevant registration and certification requirements administered by the Department of Business Development.
The application must satisfy the applicable conditions concerning nationality, company ownership, directors, authorized signatories, and proposed business activities.
Step 4: Obtain the Relevant Business Certification
Upon successful completion of the applicable procedures, a qualifying business may obtain the relevant Foreign Business Certificate and operate within the scope of its approved treaty-protected activities.
6. Benefits of the Thai–U.S. Treaty of Amity
For qualifying American investors, the treaty offers several important advantages.
Up to 100% American Ownership
Eligible businesses may be wholly owned by American nationals or qualifying American entities.
Reduced Foreign Ownership Restrictions
Qualifying businesses may benefit from preferential treatment compared with foreign investors who are subject to ordinary foreign business ownership restrictions.
Alternative to the Ordinary Foreign Business License
Eligible businesses may obtain a Foreign Business Certificate under the treaty-based framework rather than an ordinary Foreign Business License.
