The group in the South Korean capital was led by COC President Gou Zhongwen, who is also the Minister of the General Administration of Sport of China.

Choue and Gou discussed the development of takewondo in China, and in particular the World Taekwondo Grand Slam Champions Series which was held for the first time in Chinese city Wuxi in December and January.

The inaugural event, which is open to the world's top taekwondo athletes, was unveiled by Choue in July.

Its purpose is to professionalise and upgrade taekwondo's commercial appeal and media profile, with the introduction of new technology to engage television viewers and fans a key feature.

Each year, the Series will consist of separate tournaments to represent each Olympic taekwondo weight category - four men's and four women's.

The total prize money offered in each of the eight separate tournaments during December and January was $800,000 (£614,000/€686,000).

The winner in each weight category took home $70,000 (£54,000/€60,000).

Wuxi will also host the next two editions of the Series through to 2020.

Song Keqin, the secretary general of the COC, was also present in Seoul alongside the deputy director general of the general office of the general administration of sport of China, Li Hui.

The vice president of the Grand Slam Champions Series Organising Committee, Sun Dejun, was another to attend.
