LONDON - The International Olympic Committee and the Badminton World Federation must shoulder some responsibility for the match-throwing scandal at the 2012 Games, according to Chinese state media.The IOC has asked China, South Korea and Indonesia to investigate four women’s doubles pairs who, in farcical scenes on Tuesday, tried to lose their matches to secure easier draws in the knockout rounds.The request followed an admission by China’s head badminton coach Li Yongbo that he was to blame after top seeds Yu Yang and Wang Xiaoli deliberately played to lose in the opening round-robin phase."The Chinese badminton team is at fault but they have not committed a heinous crime. Li Yongbo gave a quick and sincere apology,” said the influential Global Times.
