China 'likely' to sweep all four Olympic golds

China's table tennis chief has backed his players to sweep all four titles at next year's Olympics, bucking the trend of Chinese sports officials downplaying prospects of a gold rush for the host nation.

Xu Yinsheng, speaking at the Asian Championships in the eastern city of Yangzhou, said he expected China to match their domination of the 1996 Atlanta and 2000 Sydney Olympics.

"It's very likely that China will sweep the four golds," the president of the Chinese Table Tennis Association said.

"I am only worried about home advantage turning into a double-edged sword."

China won six of the seven titles on offer in Yangzhou last weekend, spearheaded by world number one Zhang Yining leading a podium sweep in the women's singles.

"Chinese women are odds-on favourites for the singles title, while the men's singles is the most difficult," former world champion Xu said.

There were all-China finals in the four Olympic events and the only title the host country did not win was the mixed doubles.
