Radev, World Taekwondo President Chungwon Choue and Taekwondo President Slavi Binev were special guests at the opening of the Championships, where more than 1,250 athletes from 90 countries are due to compete.

Addressing the crowd Radev said: "It is my great pleasure and honour to welcome you with the opening of the World Taekwondo Junior Championships.

"For centuries, ancient combat sports developed perfection of the physique and character, provided education in discipline and responsibility, and promoted respect not only for the partner, but also for the opponent.

"That is why even today taekwondo is one of the most popular sports, but not only that, taekwondo is a symbol of peace and good neighbourliness.

"To you, dear competitors, I wish you good health and many sporting successes. Be an example of the principles of fair play and values in physical education and sports."

Following the Opening Ceremony, medals were contested across three categories - the women’s under-42 kilograms, men’s under-45kg and women’s under-44kg.

In the women’s under-42kg category, gold went to Iran’s Sogand Shiri, who defeated Turkey’s Hayrunnisa Gurbuz in two close rounds.

The men’s under-45kg category saw gold go to Yeonui Choo of South Korea who narrowly overcame Yu-Chi Li of Chinese Taipei in two tight rounds, with Choo’s more accurate kicking helping him take victory.

In the women’s under-44kg Natkamon Wassana of Thailand won in three rounds against Parnia Salmani of Iran, with a big second round helping Wassana to the win.

Action is scheduled to continue tomorrow in Sofia.
