DOHA, Dec. 12 (Xinhua) -- Olympic champion and world record holder Liu Xiang of China rounded off his sizzling season in style with a runaway victory in the men's 110m hurdles at the Asian Games on Tuesday.

    The 23-year-old Liu, who shattered the world record when he clocked 12.88 seconds at an IAAF meet in Lausanne in July this year, finished in a Games record of 13.15 to retain his Asiad title. Four years ago, he won the 110m hurdles in 13.27.

    His teammate Shi Dongpeng took silver with a personal best time of 13.28, and Japan's Masato Naito had bronze in 13.60.

    "I didn't expect myself to run so fast, the time of 13.15 was a pretty good result," said Liu.

    "The standard of the men's 110m hurdles at this Games was much higher than that in Busan," he added.

    Although Liu was one of the few world class athletes in track and field events after Japan's Olympic hammer throw champion Koji Murobushi and two-time world 3,000m steeplechase champion Saif Saaeed Shaheen of Qatar pulled out due to injuries, only a few hundred spectators turned out at the Khalifa Stadium to watch the 23-year-old Shanghai native demolish his rivals in the final.

    Liu said he was very satisfied with his performance in the 2006season, which saw him win eight out of 10 international competitions.

    "This year was another peak for me following the Athens Olympic Games," he said.

    Liu shocked the world in Athens 2004 when he won the Olympic gold medal with a then world-record-tying time of 12.91 seconds.

    Liu's coach Sun Haiping said he was also delighted with the results.

    "Liu's time was under 13.20, and Shi gave his best ever running, so I am extremely satisfied," said Sun.

    Heavily favored to win this last race of the season, Liu had set a modest target of 13.20 seconds before the Asian Games.
