Meanwhile, in the group B, Poland's Joanna Łochowska, Japan's Kanae Yagi, Canada's Rachel Leblanc-Bazinet, Chinese Taipei's Chiang Nien-hsin and Solomon Islands' Mary Kini Lifu earned their top 14 spots.
Two lifters from the previous Olympics - Diaz (silver medallist) and Yagi - returns for the event.
During the snatch, all lifters are well in first attempts, except South Korea's Ham Eun-ji and Yagi who failed to complete.
Uzbekistan's Muattar Nabieva later sets new Olympic record for heaviest snatch ever to be lifted.
During the Victory Ceremony, Diaz, Liao (who had all clean attempts in both parts) and Chinshanlo are awarded medals by Lundahl and Cojuangco-Jarowski.
