In the men's individual kata event, Cameroon's Mbomi Nestor beat Mbole Armel of the Central African Republic 17-9 while in the female individual kata event; Sandrine Doue beat Yombi Carole 19-4 on points. In the kata team events, Cameroon beat Jamaica 15-12 whereas in the randori team event Cameroon again beat Jamaica 17-8 in the men's category while the women from Cameroon beat Burundi 20-4.
