The Chinese stars, who also won Olympic gold in Sydney, are seeded fourth here but had too much quality for top seeds Lee Jae-Jin and Lee Hyo Jung in Saturday's second semi-final.
Hyo Joo Kim, the 17-year-old South Korean player who played in a group with 17-year-old Ariya Jutanugarn and 15-year-old New Zealand amateur Lydia Ko, was second along with Hee Kyung Seo and late starter Suzann Pettersen.
Among the up-and-coming golfers is Kim Hyo-joo, a 17-year old who recently signed a sponsorship deal that topped the value of Pak Se-ri's own record endorsement deal in 1998 and has already won on the Korean and Japanese tours.
