Teenage Thai Ratchanok Intanon won her first badminton world championship title when she upset Olympic champion Li Xuerui in the women's singles on Sunday to end China's decade of domination in the event.
In the men's singles, Lin Dan overcame a year off to retain his title with another closely fought battle with old adversary Lee Chong Wei of Malaysia, who retired and was taken off court on a stretcher at match point down in the third set.
Lin's win was his fifth world championship and China's sixth consecutive one in the men's singles but their proud run in the women's event ended.
Ratchanok, 18, beat Li 22-20 18-21 21-14 in Guangzhou, China, to become the first Thai to win the world championship and first non-Chinese woman since Denmark's Camilla Martin lifted the title at home in 1999.
World number one Li led 19-12 in the opening set but Ratchanok came storming back to take it 22-20, the first set the Chinese had dropped all week.
