However, the Koreans won the men's singles through Son Wan-ho, men's doubles (Kim Gi-jung-Yoo Yeon-seong) before Sung Ji-hyun clinched the women's singles for the winning point.

"We have an even chance of winning the title now…thanks to Japan who knocked out top seeds and favourites China," said Kyung-jin after the win over Thailand.
"It will be a good and interesting final. Both teams have an even chance but with China out we would rate our chances just a good."
Wan-ho put Korea on level terms with a 21-18, 21-7, 21-19 win over Suppanyu Avihingsanon before Gi-jung-Yeon-seong won their doubles match against Nipitphon Phuangphuapet-Dechapol Puavaranukroh 23-21, 21-17 for a 2-1 lead.

The Japanese displayed plenty of fighting spirit and even head coach Park Joo Bong was surprised with the "Saumrai Spirit" his players. In the same breath Joo Bong did not take the credit away from China.
"China is still the best team in the world. We won because of our tremendous fighting spirit…it even surprised me. I did not expect my team to win the men's singles.
It was a stunning comeback by the Japanese who lost the mixed doubles in the opening match with China's Zhang Nan-Chen Qingchen carving out a 22-20, 21-19 win over Japanese youngsters Yuta Watanabe-Arisa Higashino in 41 minutes.
