SHANGHAI (AFP) - China stayed perfect Sunday in the World Championships diving events as grieving British star Tom Daley's hopes were hit by a last-minute illness to his 10m synchro partner Waterfield. Olympic champion Huo Liang combined with new partner Qiu Bo to claim his third straight world title in the event. Huo and Qiu totalled 480.03 points, leaving Germany's Patrick Hausding and Sascha Klein 37.02 adrift in the silver medal position with Ukrainians Oleksandr Gorshkovozov and Oleksandr Bondar claiming bronze. Individual 10m world champion Daley, 17, finished sixth with Waterfield. "I think our performance went okay considering the situation. Me and Pete haven't been able to train for a week because Pete's been a little bit unwell," said Daley. Daley said competing had helped lift his spirits after the loss of his father, Robert, who was his ever-present companion on the diving circuit. Huo and Qiu also overcame obstacles to claim gold. The two had been together for just a matter of months after Lin was ruled out through injury, underlining the Chinese diving dynasty's extraordinary strength in depth. China also won the women's 3m synchro on Saturday as they target the first ever clean sweep of diving titles, after winning seven out of 10 two years ago in Rome. Russia's synchronised swimming queen Natalia Ishchenko claimed the event's first gold -- and her 11th world title -- when she won the technical solo ahead of China's Huang Xuechen and Andrea Fuentes of Spain. The Spanish swimmer did a great job," she said. In the men's diving final, Huo and Qiu stamped their authority with a piked backwards 3.5 somersault and rounded it off with a backwards two-and-a-half somersault with two-and-a-half twists which won them 98.28 points. American David Boudia and his partner Nick McCrory rued a botched fifth dive which kept them out of the medals, despite placing second in the preliminaries.
