World and Olympic champion Lin Dan added a first Superseries Finals title to his trophy haul yesterday with a 21-12, 21-16 success over Chinese compatriot Chen Long in the men's singles final in Liuzhou, south China's Guangxi Zhuang Autonomous Region.

China also lifted the women's doubles and mixed doubles crowns but Danish men's duo Mathias Boe and Carsten Mogensen beat Chai Biao and Guo Zhendong 25-23, 21-7 to prevent a clean-sweep.

Wang Xiaoli and Yu Yang beat Ha Jun-eun and Kim Min-jung of South Korea 21-8, 21-12 to win the women's doubles final while the mixed doubles title went to Zhang Nan and Zhao Yunlei who beat compatriots Xu Chen and Ma Jin 21-13, 21-15.
