Lin Dan of China defended his title in men's singles as China collected all of the five gold medals on offer for the first time at the Asian championships on Sunday.

Japanese men's doubles combination Hirokatsu Hashimoto-Noriyasu Hirata were the only non-China representative in the final. Unfortunately, they were not able to withstand the attacks of top seeds Cai Yun-Fu Haifeng, who won 21-12, 21-15.

Hashimoto and Hirata weren't the only Japanese to fall to the thee-time world champions who started their campaign on the right note after brushing aside Naoki Kawamae-Shoji Sato in the opening match on Wednesday.

In the women's doubles final, second seeds Wang Xiaoli-Yu Yang showed no mercy as they outclassed team mates Tian Qing-Zhao Yunlei 21-13, 21-10 in the match that lasted just 33 minutes.

Wang Xiaoli-Yu Yang were hardly tested in the tournament, having secured straight wins over all their opponents.

There was some excitement in the mixed doubles final as Xu Chen-Jin Ma gave first seed Zhang Nan-Zhao Yunlei a run for their money before losing 15-21, 21-15, 25-23 in a match that ran over an hour. It was sweet revenge for the second seeds who had lost to their team mates in the All-England final a month ago.
