The International Taekwon-Do Federation (ITF), which was formed in Seoul Korea in March of 1966, will perform joint demonstrations with the World Taekwondo (WT), formerly called the WTF, also founded in Seoul Korea in May of 1973. These 4 performances are a result of the historic Protocol Of Accord signed at the occasion of the last Youth Olympic Games by Prof. Chang Ung, PhD, past president of the ITF and Official IOC Member and Dr. Choue Chung-Won, PhD, President of the WT. Prof. Chang now serves as Honorary Life President of the ITF, after being succeeded by Master Ri Yong-Son, a long time ITF official serving in many capacities at the ITF Headquarters in Vienna Austria. The ITF was relocated to Vienna Austria in 1985 from Toronto Canada, where it was located from 1972 to 1985, by the late General Choi Hong-Hi, the principle founder of the Original Taekwon-Do. General Choi served as founding President of the ITF until his passing in 2002. President Ri also serves as a Vice President of the National Olympic Committee of Pyongyang, Korea.
