Siam Legal International Highlights Treaty of Amity Advantages for American Businesses Expanding into Thailand

Bangkok, Thailand - October 15, 2025 - PRESSADVANTAGE -

Siam Legal International, a Bangkok-based law firm with over 22 years of experience in corporate law and foreign business registration, emphasizes the significant advantages available to American entrepreneurs and investors through the US-Thailand Treaty of Amity as bilateral trade continues to strengthen between the two nations.

The Treaty of Amity, signed in 1966, provides American companies with unique privileges in Thailand that are not available to other foreign nationals. Under this agreement, US citizens and businesses can own a majority stake or even 100 percent of a Thai company, bypassing the typical restrictions imposed by Thailand's Foreign Business Act that limit foreign ownership to 49 percent in most sectors.

This special relationship between the United States and Thailand grants American companies national treatment status, meaning they receive the same rights as Thai companies in most business sectors. While certain areas remain restricted, including land ownership, communications, transportation, banking with depository functions, and exploitation of natural resources, the treaty opens substantial opportunities in consulting, technology, manufacturing, and service industries.

"The Thailand Treaty of Amity represents one of the most advantageous legal frameworks for American businesses looking to establish operations in Southeast Asia," said Rex Baay, a spokesperson from Siam Legal International. "With Thailand serving as a strategic gateway to the ASEAN market of over 650 million consumers, American companies gain not just access to Thailand but a launching pad for regional expansion."

The growing US-Thailand trade relationship, valued at over $65 billion annually, underscores the importance of this treaty for American businesses. Thailand's position as a regional manufacturing and logistics hub, combined with its developed infrastructure and skilled workforce, makes it an attractive destination for American investment across diverse sectors.

Siam Legal International provides comprehensive support for American businesses navigating the treaty registration process. The firm's services encompass initial eligibility assessment, business structuring advice, and complete registration with the Thai Ministry of Commerce. The legal team also manages the critical certification process through the US Commercial Service and Thailand's Ministry of Foreign Affairs, ensuring full compliance with treaty requirements.

Beyond initial registration, the firm offers ongoing support, including corporate governance advisory, tax planning, and regulatory compliance services. This comprehensive approach helps American companies maintain their treaty privileges while adapting to Thailand's evolving business environment.

The treaty's benefits extend beyond ownership rights. American companies enjoy protection against discriminatory restrictions, enhanced investor confidence, and streamlined market access compared to businesses from countries without similar agreements. These advantages prove particularly valuable as Thailand continues to develop its Eastern Economic Corridor and positions itself as a regional hub for advanced industries.
