Cai Yun and Fu Haifeng of China won the World Championship title in the men's doubles event, the final of the World Championships, beating Lee Yong-dae and Jung Jae-sung of Korea in the final. It was their second men's doubles title, having previously won in Madrid in 2006. Cai Yun and Fu Haifeng won the first game by a score of 21–18. The Koreans then won the second game by a score of 16–21 to draw level. The third game saw the two pairs exchange the lead several times with a one-point difference before exchanging several match points. 28–26 was the final score, with the Chinese declared winners on their sixth match point. Retired Chinese badminton player and now coach of his national team, Li Yongbo, watched from the sidelines what was later termed "a classic that will be often recalled as one of the best men’s doubles matches in the recent history of the sport".
