South Korean presence in the men's singles final at the Super Series event was already assured due to two of the country's stars, Son Wan-ho and Lee Hyun-il, squaring off in the last four.

It was sixth seed Son who triumphed in three games, with the 28-year-old beating the veteran former World Championships bronze medallist 21-13, 14-21, 21-10.

He will now go for the title against China's unseeded player Qiao Bin, who ended the run of Hong Kong's Wong Wing Ki, 21-18, 21-16.

In the women's competition an all-South Korean semi-final once again guaranteed home progression, and it was fifth seed Sung Ji-hyun who eased through against team-mate Kim Hyo-min, 21-5, 21-10.

She will now play Japan's former double world junior champion Akane Yamaguchi, after the seventh seed beat her compatriot Minatsu Mitani 21-17, 21-11.

In the men's doubles, Korean progression was achieved by top seeds Lee Yong-dae and Yoo Yeon-seong, who came through against Huang Kaixiang and Wang Yilu of China, 21-11, 21-16.

They will now meet another Chinese pair, seventh-seeded Li Junhui and Liu Yuchen, in the final, after their 18-21, 21-15, 21-13 win against Malaysia's Goh V Shem and Tan Wee Kiong.

South Korea's women's doubles top seeds Jung Kyung-eun and Shin Seung-chan also reached the final as they beat compatriots Chang Ye-na
and Lee So-hee 23-21, 21-15.

Their reward is a clash with China's Luo Ying and Luo Yu, who ended European interest by beating Denmark's Christinna Pedersen and Kamilla Rytter Juhl, 21-15, 17-21, 21-12.

The mixed final will pit South Koreans Ko Sung-hyun and Kim Ha-na, the top seeds, against China's Zheng Siwei and Chen Qingchen.

The home pair came from behind to beat Malaysia's Chan Peng Soon and Goh Liu Ying, 15-21, 21-14, 21-15, with the Chinese duo seeing off Hong Kong's Lee Chun Hei and Chau Hoi Wah 21-16, 21-18.
