The organization was set up in 1995 by parliament resolution, and is incorporated by the Royal Thai Government and sanctioned by the Sports Authority of Thailand, under the Ministry of Tourism and Sports. 

The Council’s primary objective is to maintain and promote excellence in the art of Muaythai. This is predominantly as a cultural art form, in addition as a form of self-defence and a popular ring sport. Together with the above-stated aims, the WMC has the government’s directive to regulate all Muaythai competitions worldwide, in accordance with the government-approved Articles of Association.

The Council has been charged with the responsibility for expanding Muaythai worldwide. This involves supporting youth interest and athletes to learn Muaythai’s skills and assist in the pursuit of excellence in the art.

The Council not only enforces equality in all matches, it is the sole body for sanctioning of championship bouts of a world standard. The worldwide members of 120 countries in all 5 continents and the WMC are working together to hold shows, events, seminars, instructor courses and referees and judges courses; to further increase the standard of Muaythai around the world.

The Head Office of the WMC is located at the Sports Authority of Thailand Complex in Bangkok where Thailand-related affairs are dealt with as well as the international office in the heart of Bangkok.
