SHANGHAI, Sept. 17 (Xinhuneta) -- China's Olympic champion Liu Xiang beat four-times world champion Allen Johnson of the United States in a dramatic men's 110 meters hurdles here tonight at the Shanghai Athletics Grand Prix.

    Other Olympic champions Justin Gatlin of the United States, Yelena Isinbayeva of Russia and Kenenisa Bekele of Ethiopia sailed to victories easily in front of more than 40,000 yelling fans.

    Liu, who keeps the world record of 12.91 in the men's 110m hurdles, caught up Johnson in the final stage with a winning time of 13.05 seconds. Johnson clocked 13.20 for the silver.

    Arnold Dominique of the United States, who ranked third in the world this season, was disqualified of the race due to a false start.

    "I felt very good. It is my second best result," Liu said at the press conference. "I was not effected by the three false starts."

    Gatlin, 22, beat a world class field to win the 100m gold in 10.01 seconds, ahead of his teammate Leonard Scott and Francis Obikwelu of Portugal. Scott clocked 10.09 and Obikweilu was timed 10.11.

    "I am satisfied with the race, especially the track and the local fans," said Gatlin, who came to China for the first time. "Shanghai gives me a very good impression. I will come here again next year."
