Veteran striker Li Ying, who scored the sole goal for China at last year's World Cup in France, drew first blood in the fifth minute when she dodged an opposing defender before firing the ball past Thailand goalkeeper Tiffany Sornpao.

Zhang Xin doubled China's lead five minutes later as she curled the ball in from the left side of the area.

Wang Shanshan, who was recalled to the Chinese team before they flew to Australia, headed in their third goal in the 40th minute when a pass from Li found her unmarked.

Tang Jiali scored in the 43rd and 51st minute to expand China's lead to 5-0, before Li headed in her second of the match at the 64th minute mark.

Thailand, who lost to Chinese Taipei 1-0 at their first qualifying match, pulled back one consolation goal through Silawan Intamee in the 80th minute.
