Corporate & Commercial


The US Amity Treaty was signed between the United States of America and the Kingdom of Thailand with the purpose of promoting trade, commerce, cultural understanding and offering mutual legal rights for both countries.

Under the US Amity Treaty, American citizens and corporations wishing to establish a business activity in Thailand may enjoy the following major benefits:

  • Are exempt from most of the restrictions imposed by the Foreign Business Act

  • May own the majority or all of the shares of a company, branch office, or representative office established in Thailand

  • May form the majority of directors

  • May engage in business on the same basis as Thai companies, except for communications, transportation, fiduciary functions, land ownership, exploitation of land or other natural resources

In order to enjoy the protection of the US Amity Treaty, American investors must obtain an approval, a Certificate of Treaty Protection (also called Foreign Business Certificate), issued by the Thailand Department of Commerce. The process of obtaining this approval can be lengthy and time-consuming, especially for those unfamiliar with the relevant steps, rules and procedures, and professional assistance is highly recommended.

At Antares, our experienced lawyers can handle the complete application process for you. We ensure that the process of creating your entity under the US Amity Treaty is made in compliance with the Thai regulations, while avoiding any unnecessary cost or delay.
