"I am proud to share with you that seven athletes from the inaugural GP Challenge went on to win medals in other WT-promoted events," said Choue.

"This would not have been possible without the GP Challenge.

"Therefore, World Taekwondo is committed to continue promoting such opportunities for aspiring athletes, including for Para taekwondo which will take place next month.

"To all athletes, I wish you all the best in the GP Challenge and look forward to even greater achievements from you."
