Former Olympic champion Wang Liping announced her retirement on Wednesday after winning the women's 20km race walking gold medal at the East Asian Games.

"It might be my last race, and I will retire after the games," said the 29-year-old.

Wang, the Sydney Olympic gold medalist, clocked the fastest time of 1 hour 34 minutes 31 seconds, just half a minute ahead of runner-up Kim Mijeong of South Korea.

"I feel exhausted after the Chinese National Games, and I was not in good form today," said Wang, the mother of a three-year-old girl.

"It was a grueling race, but I am happy I survived," she added.
