Saeid Mollaei of Iran beat Japan's Sotaro Fujiwara in a repeat of the final at last year's World Championships to claim the gold medal in the men's under-81 kilograms division at the International Judo Federation Grand Prix in Hohhot in China.
World champion Mollaei again reigned supreme over his Japanese opponent, throwing Fujiwara for ippon to top the podium at Inner Mongolia Stadium.

The bronze medals in the weight class were claimed by Germany's Dominic Ressel and South Korea's Lee Sung-ho.
Hidayat Heydarov of Azerbaijan continued his superb run of form as he clinched his second straight victory on the IJF World Tour.

Arthur Margelidon of Canada and Igor Wandtke of Germany each took home a bronze medal.
Paris Grand Slam bronze medallist Saki Niizoe of Japan triumphed in the women's under-70kg category with victory over Sweden's Anna Bernholm.
