Lethwei is not well known in the United States. Many of its techniques, tactics, strategies, training methods, and cultural traditions remain unfamiliar to the American public. The Lethwei Association of America, also known as Lethwei America, was established in 2018 to promote awareness, education, and practice of Lethwei in the United States. Lethwei America is an authorized representative for Thut Ti Lethwei Global under the direction and guidance of Saya Win Zin Oo, founder and senior coach of the Thut Ti Lethwei Club of Yangon, Myanmar.

Lethwei America offers an instructional and training platform designed to provide a comprehensive, ground-up learning experience in Lethwei. Its program is based on proven pedagogical principles, evidence-based best practices, and extensive teaching and coaching experience. The Lethwei America program follows the curriculum developed and promoted by Thut Ti Lethwei Global.  The curriculum is founded on the principles of  authenticity, diversity, flexibility, inclusion, and respect. It emphasizes the various facets of Lethwei as a fighting art, combat sport, and culture.

Lethwei America, in conjunction with Thut Ti Lethwei Global, offers an instructor preparation program designed to prepare the individual to teach the techniques, tactics, strategies, and cultural aspects associated with the practice of Thut Ti Lethwei. The Lethwei America program provides a flexible format of instruction and may be taught through stand-alone course offerings as well as incorporated into existing kickboxing or martial arts programs
