Zhang beat King 7-6 (7-1), 6-1 in Saturday's final in Guangzhou for her first WTA title. That lifts her from 112th to 74th in the rankings, just short of her career best of No. 73 in April 2011.
King, who was seeking her first WTA championship since October 2006, improved 30 places to 94th in the rankings. Her career high is 50th, which was reached a month after she won the PTT Bangkok Open seven years ago.
World No. 4 Agnieszka Radwanska defeated Anastasia Pavlyuchenkova 6-7 (6-8), 6-3, 6-4 in winning the KDB Korea Open Sunday. It was Radwanska's 13th WTA title. It didn't change her ranking but Pavlyuchenkova moves to No. 29, up three from a week ago.
It was announced that No. 3-ranked Maria Sharapova and Radwanska qualified for the season-ending WTA Championships. No. 1 Serena Williams and second-ranked Victoria Azarenka had previously qualified for the eight-player, invitation-only event.
