RIO DE JANEIRO -- China's Deng Wei won the women's 63kg weightlifting by breaking two world records in just five lifts at the Rio Olympics on Tuesday.

Deng, world champion in 2014 and 2015, came into the clean and jerk competition with a four-kilo buffer in the snatch. After jerking 138kg in her first attempts, she had already won the gold medal with a total of 253kg as other opponents had finished all the lifts.

Then the 23-year-old lifter began her solo in the fifth attempts, putting an ambitious 147kg above her head steadily for a total of 262kg, breaking two world records in jerk and total by one kilo respectively.

Choe Hyo Sim of the Democratic People's Republic of Korea, bronze medalist at the world championships in 2015, clinched the silver medal at 248kg while Karina Goricheva of Kazakhstan, third in 2015 world ranking, grabbed the bronze at 243kg.

Another title favorite Lin Tzu-chi of Chinese Taipei missed the women's 63kg final as the world record holder was given a provisional ban on the eve of the competition here for abnormality in her urine sample, local media said.
