Despite tearing a back muscle before the match, Keïta won the gold medal for the Heavyweight (84 kg) division 2007 World Taekwondo Champion in Beijing by beating Iranian Morteza Rostami 3 to −1 in the final. He is the first Sub-Saharan African to hold the title of Taekwondo World Champion, and has become a national hero in Mali. Keita himself has reflected that "Winning the world title was almost unthinkable for an African, or someone from a developing nation".
