DOHA -- Sun Yingsha disposed of Japan's Mima Ito in straight sets in the women's singles semifinals on Saturday to confirm a clean sweep of the event's medals for China at the World Table Tennis Championships.

Having beaten the eighth seed 11-7, 11-5, 11-9, 11-4, the world No. 1 will take on either Wang Manyu or Chen Xingtong in an all-Chinese final on Sunday.

"I had perfect execution of strategy for this game," said Sun.

Sun added that she anticipated a "very tough" final, saying she would try to pull off her best game.

"Every time I met her, Sun quickened her pace. She is so fast and her topspin strike is so potent," said Ito.

Sun will play with Wang Chuqin in the mixed doubles final against Japan's Maharu Yoshimura and Satsuki Odo later in the day.
