BEIJING, Aug. 16 (Xinhua) -- Women gymnasts from China and the United States are likely to have another tough meet for the floor exercise and vault gold medals on Sunday, while the pommel horse title seems a bet for China's male gymnasts at the Beijing Olympic Games.

    On vault, first-placed Alicia Sacramone of the U.S. may hope to make up for her failure which cost her teammates the chance for a women's team title, but she will definitely meet tough challenge from China's Cheng Fei, the vault gold medallist in three consecutive world championships.

    The U.S. pair Nastia Liukin and Shawn Johnson, who pocketed the women's all-around gold and silver medals and ended Chinese gymnasts' three-day gold streak, will also find Cheng, the floor exercise champion in the 2006 world championship, a worthy opponent.

    But China's male duo Xiao Qin and Yang Wei will be a 1-2 punch on pommel horse, as Xiao, known as China's "pommel horse king", is the horse gold medallist for two Worlds and Yang is also strong on the apparatus.

    The only event on Sunday which the hosts bear little hope for is the men's floor exercise, which will see a crew including Anton Golotsutskov of Russia, Kohei Uchimura of Japan and Fabian Hambuchen of Germany contending for the top notch.
