Suzhou (China), May 1 (IANS): Olympic and defending World Champion Li Xiaoxia led China's sweep of six berths at the women's singles quarterfinals here on Friday.

Yang-Xu are the only trans-national pair as other duos exited early.

The combination of Germany's Timo Boll and China's Ma Long lost their men's doubles second round match to China's Zhang Jike and Xu Xin.
