World karate champion Nguyen Hoang Ngan won two gold medals at the fifth International Istanbul Open Karate Tournament.
The annual three-day event which attracted 850 participants from 35 countries wrapped up on September 19.
Ngan, 26, performed with impressive skills in the individual female kata (performance) event to secure a gold.
The Hanoian artist defeated the host athlete Kubra Akarsu 5-0 in the final match.
Akarsu took the silver medal, while Mohsa Afsone of Iran and Do Thi Thu Ha of Vietnam shared the bronze medal.
Ngan along with teammates Thu Ha and Nguyen Thu Hang triumphed in the senior team kata event.
This was the second time the trio won a gold medal. The team won their first gold at the 25th Southeast Asian (SEA) Games in Laos last December.
The 26-year-old is a favourite to win a gold medal at the coming 16th Asian Games (ASIAD) that will be held in Guangzhou, China on November 11-27.
She will compete at the world championships in Belgrade, Serbia later this month to prepare for ASIAD.
At the Asian Karate Championships in China last year, Ngan bagged a silver medal. Two years ago, she also clinched the champion in the World Karate Championships in Tokyo, Japan./.
