Choi Hong Hi spoke to a select group of ITF officials and high-level instructors on his deathbed at Pyongyang Hospital. It was recorded that there might be no misinterpretation of his intentions regarding the future of the ITF. The following is an excerpt:

You probably might know Mr. Chang Ung well. It is time to introduce Mr. Chang Ung proudly in public. Please carry on propaganda that Mr. Chang Ung is the tallest and in the highest position in the ITF. If only I had been as tall as Mr. Chang Ung, I could have had less opponents, however, as my body was so tiny that there were many opponents. Thus, all alone, I could not but fight against them for so long. But I have never been worn out for the justice was on my side. I have always worried about a successor to the President, however, my mind is set at ease for there is Mr. Chang Ung. These last words were witnessed by: Mr. Rhee Ki Ha, Grand Master and former Vice-President of the ITF; Mr. Tom MacCallum, Master and the Secretary General; Mr. Leong Wei Meng, Master and the Chairman of the Consultative Committee; Mr. Kwang Sung Hwang, Grand Master, spokesman and special aide; Mr. Park Jong Soo, Grand Master and a member of the Consultative Council; Mr. Hwang Jin, Master and a member of the Consultative Council; Mr. Hwang Bong Yong, Chairman of the Korean Taekwon-Do Committee; Mr. Jong Jae Hun, Secretary General of the International Martial Art Games Committee and Mr. Rang Bong Man, Secretary General of the Korean Taekwon-Do Committee

A special Congress of the ITF and memorial was held at the People's Palace of Culture in Pyongyang on September 22, 2002, after Choi's death. It was here that Presidents and representatives from 46 national Taekwon-Do federations unanimously elected Mr. Chang Ung, member of the International Olympic Committee, as president of the ITF. He was re-elected as president on October 13, 2009. Legitimacy as ITF President

Senior Grandmaster Phap Lu's Open Email
Senior Master Phap Lu stated on October 22, 2002, in an Open email to Taekwon-Doists that, 
"General Choi did not speak his last words with the constitution in mind. He spoke as a CREATOR of the art. When he was alive what he said was law, in death are his words are no longer valid?" It is here that he explains the background behind General Choi's reason for choosing Chang Ung as a successor. "That was why General Choi handpicked Mr. Russell MacLellan as the Senior Vice-president to fulfill the role as acting President if anything happened to General Choi. At this time Mr. Chang Ung’s name was never mentioned. Our beloved Founder still waited for his son to visit him at the hospital in Pyongyang, but his last hope TOTALLY vanished when the nine people visited Gen. Choi without his son’s presence in mid of June 2002 after the International Gen. Choi’s Cup in Ottawa, Canada...Since February 2002 there has been a recent rapid change in the political situation in both KOREAs. After General Choi was admitted to the hospital in North Korea, General Choi saw the light of unification in both TAEKWON-DO and North and South KOREAs. With Mr. Chang Ung’s I.O.C. experience, knowledge and talents, as well as his relationship with Mr. Ung Yong Kim, his various meetings with both North and South Koreans TaeKwon-Do Committees members, General Choi Hong Hi, handpicked Mr. Chang Ung as his successor before his departure. The sudden appearance of Mr. Chang Ung surprised much of the PRESENT CORE ITF MEMBERS as he was never spoken of by General Choi. ""Our beloved Founder General Choi Hong Hi DID NOT PICK Mr. Chang Ung in favor of North Korea, but he picked him up as successor because OF THE PRESENT POLITICAL CLIMATE as well as his leadership qualities. This was the BRILLIANT FUTURE VISION of our beloved Founder and Father. If you were Mr. Chang Ung I believe that regardless of whether you were a Canadian, Italian, Korean or Argentinian you would be picked too. THAT IS OUR GENERAL CHOI, everything fits for Taekwon-Do. If it fits he would use it, because he believed that these were gifts from Heaven to him. Gen. Choi used to tell us that his Parents gave his name CHOI HONG HI and HEAVEN gave his name TAEKWON-DO. He was even afraid that nobody would know what Taekwon-do would be, he asked people to cover his coffin with the words TAEKWON-DO. I believe that whatever the outcome will be: IT IS THE LAST WISHES OF GENERAL CHOI HONG HI. We at least own him for these. "People in the ITF see it as a great honor to meet him in person.
