The three-day G-4 event, due to start on November 25, will be the first major women’s taekwondo event held in Saudi Arabia and has attracted entries from 170 athletes representing 36 countries.

Athletes will compete in eight weight categories in matches comprising three two-minute rounds at the Green Halls in the Saudi Arabian capital.

The competition will implement a single-elimination system with the first two days of competition dedicated to preliminaries and semi-finals before the finals on November 27.

Winning athletes will secure 40.0 ranking points with second and third place taking 24 and 14.4 ranking points respectively.

"We are eagerly awaiting the first ever World Taekwondo Women’s Open Championships in Riyadh," World Taekwondo President Chungwon Choue said.

"Taekwondo is a global sport which is open to all and we pride ourselves on being a gender equal.

"We know we can develop Taekwondo further and by hosting the Women’s Open Championships in Riyadh we will help promote gender equality in the Middle East and around the world.

"We have Olympians, world champions and aspiring athletes from four continents competing at the competition and I have no doubt they will showcase the very best of taekwondo."

Choue has been trying to promote women’s taekwondo in Saudi Arabia for several years as the country continues to offer female athletes more opportunities to compete.

"I am confident that the Riyadh2021 World Taekwondo Women’s Open Championships will serve as another wonderful opportunity for an exchange of friendship and culture among the top athletes from the globe, building on the already great harmony we already enjoy."
