China downed Argentina 2-0 in the last Olympic women's soccer group match on Tuesday, advancing to the knockout round as the first in Group E.

Han Duan, who missed last match against Canada due to injury, opened the scoring for the home side in the 52nd minute.

Chinese midfielder Bi Yan powered a free kick into the box. In a melee Han headed the ball into Argentina's defender which deflected into the net.

Only two minutes into action, substitute Gu Yasha sealed the win in the 90th minute. She coolly sent Xu Yuan's low cross from the right wing into the net with her right foot.
