The participants included a 36-member delegation, including 32 North Koreans, from the North Korea-led International Taekwondo Federation, with a 12-member demonstration team also set to stage its first-ever performance in South Korea.

"It will mark the first time the ITF will perform at a WTF event held in South Korea," the president said.

"Friendship and goodwill exchanges between the two federations will of course greatly contribute to reconciliation between South and North Korea, as well as the establishment of peace on the Korean Peninsula," he added, noting the WTF was set to send a demonstration team to an ITF event to be held in Pyongyang in September.

"I wish the achievement made by taekwondo will be repeated at the PyeongChang Winter Olympic Games next year. If a North Korean delegation takes part in the PyeongChang Winter Olympics, I believe it will greatly contribute to realizing the Olympic values of friendship and peace," President Moon said, according to a script of his remarks released by the presidential office Cheong Wa Dae in Seoul.

Also present at the opening of the taekwondo championships in Muju were Chang Ung, North Korea's sole member of the International Olympic Committee, and Ri Yong-son, the North Korean head of the ITF.

President Moon especially extended his welcome to the two, noting their journey to South Korea must have been the longest. Before his speech, Moon shook hands with Chang and exchanged a few words with him.

South Korea and North Korea remain divided and technically at war as the 1950-53 Korean War ended only with an armistice and not a peace treaty.

Earlier this week, Seoul's new sports minister, Do Jong-hwan, suggested forming a joint Korean team in women's hockey and holding skiing events at North Korea's Masikryong resort during PyeongChang 2018.

The ideas may well get some traction, as IOC President Thomas Bach is scheduled to visit Muju for the WTF championships' closing ceremony next Friday. During his stay, Bach is expected to discuss the issue with relevant parties.

In his speech, Moon said he'd once again like to feel the emotions from watching the joint march of the two Koreas in the opening ceremony of the 2000 Sydney Olympics. Moon also made references to the 1991 World Table Tennis Championships and the 1991 FIFA World Youth Championship, two competitions where the Koreas fielded joint teams.

After the Sydney Games, the two Koreas also had joint marches at the 2002 Busan Asian Games, 2003 Aomori Asian Winter Games, 2004 Athens Summer Olympics, 2006 Torino Winter Olympics, 2006 Doha Asian Games and 2007 Changchun Asian Winter Games.

For a joint march in PyeongChang to materialize, North Korea must first qualify to compete in the Olympics. North Korea didn't participate in the 2014 Winter Olympics in Sochi, Russia. For PyeongChang, the North's last shot is in pairs figure skating, and its skaters' fate will be determined in September. (Yonhap)
