BEIJING (AP) -Liu Chunhong broke three world records in the women's 69-kilogram division Wednesday, defending her Olympic title to win China's sixth gold medal in the weightlifting competition.

Liu set a new high score of 128 kg (282.2 pounds) in her third attempt in the snatch. She then lifted 158 kg (348.3 pounds) to set a new top mark in the clean and jerk.

Her total of 286 kg (630.52 pounds) also was a world record, beating the previous mark by an astounding 10 kg (22.1 pounds).

World champion Oxana Slivenko of Russia was a distant second, lifting a total of 255 kg (562.17 pounds). Ukraine's Natalya Davydova took the bronze.

Liu's performance was the most impressive yet in the weightlifting competition, which China has dominated from the start. The Olympic host has won three gold medals for women and another three for men in the sport.

Liu, who won the same category in the 2004 Olympics in Athens, said she was excited to compete in front of the home crowd and was relieved to be able to get a break from her rigorous training routine.

"What I want the most at the moment is to spend some time with my parents,'' she said. "Since the last Olympics until now I have only spent six days with my parents.''

Underscoring her superiority, Liu entered the snatch at 120 kg (264.6 pounds), 5 kg (11 pounds) higher than any of the other lifters had managed in all three attempts.

After easily clearing that weight, she set new snatch world records in her next two lifts, at 125 kg (275.6 pounds) and 128 kg (282.2 pounds), delighting the home crowd.

Even the third attempt looked easy. Instead of holding for a moment in a squat like most lifters, Liu stood up as soon as she had pulled the bar overhead. She took one small step with each foot and then remained perfectly steady.

The lift was 5 kg (11 pounds) higher than Slivenko's previous snatch world record.

The Russian, who beat Liu at last year's world championship, knew she was competing for silver from there on.

"I wanted to compete for gold and now I have ambiguous feelings,'' she said. "It's really scary to compete in a tournament like the Olympic Games. I was under huge pressure.''

In the clean and jerk, Liu took 145 kg (319.7 pounds) in her first try and 149 kg (328.5 pounds) in the second. At that point she already had set a new world record total.

Backed by the chants of the Chinese audience, she then obliterated Russian Zarema Kasaeva's clean and jerk world record to cap a perfect competition.

"I think no one will reach that in the next one to two years, and when someone does I will set more new records,'' Liu said.

Like other Chinese lifters, she wore a gold-colored cape between lifts.

"The whole team wears it and I have been wearing this for all of the recent tournaments,'' she said. "Because gold in China is the color of the dragon and it brings luck and peace.''
