    DOHA, Dec. 4 (Xinhua) -- Weightlifter Pawina Thongsuk of Thailand has competed in three different divisions in five years, and even now, she has not decided in which category she is going to lift in the Beijing Olympics.

    Thongsuk claimed gold in women's 63kg weightlifting competition after recording a world record lift of 142kg in the clean and jerkat the Doha Asiad.

    Four years ago, she was the winner in 69kg class at the Busan Asiad. Two years ago, she won the Olympic gold medal in 75kg category in Athens. And one year ago, she took the gold in 63kg inthe Doha world championships.

    "My weight even did not reach 70kg in the Athens Olympics, so it was easy for me to switch to different categories," said Thongsuk in a training in Doha.

    "I don't know in which category I am going to compete in the Beijing Olympics in 2008. It is not decided yet," she said after the match on Monday, smiling.

    The 27 year-old Thai's success in the Doha Asiad marks only the second time in Asian Games history that China have failed to win gold in women's weightlifting, the first time being at Busan 2002 when DPR Korea's Ri Song Hui took home the gold in the 53kg event.

    Thongsuk was rested from this year's world championship so she could prepare properly for the Asiad.

    According to the Bangkok Post, she hurt her left knee badly in training in Chiang Mai and "only has a slim chance of winning a medal".

    "Yes, I suffered knee injury before I came here. My coaches and doctors did a lot of work for the treatment," she said.

    Holding the gold medal in her hand, Thongsuk raised 142kg successfully in her last attempt, breaking the world record of 141kg set by Svetlana Shimkova of Russia.

    "When I have won the gold medal in my second attempt in the jerk, I thought it was time to break the world record of jerk in the final lift," she said.

    Thongsuk's main rival, Chinese Ouyang Xiaofang, suffered knee injury in her second lift in the jerk and withdrew from the head-to-head battle.

    "Even if Ouyang had not injured her knee, I would have won the gold medal anyway. I am a fighter," said Thongsuk.
