"Yang, Ki and Choi are closely related to Gwangju and have obtained a world-wide reputation," a Gwangju 2015 spokesperson said

"At the same time, they will be very active in their own fields at least until 2015.

"Therefore, their participation in various sports competitions in and out of South Korea will naturally contribute to raising the public awareness of Gwangju Universiade."

They were confirmed as ambassadors at a ceremony attended by Gwangju 2015 chairman Kang Un-Tae, also the Mayor of the city.

The Gwangju Universiade, taking place in July 2015, will involve more than 14,000 athletes, officials and judges.
