Siam Legal International, a leading law firm specializing in foreign business establishment in Thailand, emphasizes the continued advantages of the U.S.-Thailand Treaty of Amity following the recent announcement of the Framework for a United States-Thailand Agreement on Reciprocal Trade on October 26, 2025.
The new reciprocal trade framework aims to strengthen bilateral trade, investment, and market access between the United States and Thailand. This development builds upon the foundation established by the 1966 U.S.-Thailand Treaty of Amity and Economic Relations, which continues to provide American citizens and businesses with significant advantages when establishing operations in Thailand.
Under the Treaty of Amity, U.S. citizens maintain the right to hold majority ownership in Thai companies and receive national treatment comparable to local firms, advantages not available to investors from most other countries. The newly announced framework expands cooperation into modern business areas, including digital trade, intellectual property protection, agriculture, environmental standards, and labor rights, creating an enhanced environment for U.S. business expansion in Thailand.
"The combination of the existing Treaty of Amity provisions and the new trade framework represents an unprecedented opportunity for American businesses looking to establish or expand operations in Southeast Asia," said Rex Baay, Operations Manager at Siam Legal International. "Thailand's strategic location, coupled with these favorable legal frameworks, positions the country as an ideal hub for U.S. companies targeting the ASEAN market."
The announcement coincides with significant U.S.-Thai commercial deals in agriculture, energy, and aviation sectors, signaling renewed confidence in Thailand's economy and its role as a regional business hub. These developments underscore the growing importance of the bilateral economic relationship between the two nations.
Siam Legal International has extensive experience assisting American investors with navigating Thailand's foreign business laws, including Amity Treaty certification, company registration, and Board of Investment (BOI) compliance. The firm's corporate division provides comprehensive legal support for businesses seeking to leverage the treaty's benefits, from initial company formation through ongoing regulatory compliance.
The Treaty of Amity allows American businesses to operate in sectors typically restricted to Thai nationals, including wholesale and retail trade, services, and manufacturing. Combined with the new framework's focus on digital trade and intellectual property protection, American entrepreneurs now have access to an even broader range of opportunities in the Thai market.
