The pre-tournament favourites go marching on in the Africa Cup of Nations with a 3-0 win over co-hosts Equatorial Guinea, Didier Drogba scoring the first two goals.
The Chelsea centre-forward and Ivory Coast captain found the target in each half to make him joint tournament top scorer with three goals. Yaya Toure hit the third.
It was a straight-forward win against the lowest-ranked side in the tournament whom despite a partisan crowd had caused a big surprise by beating Senegal in the group stage.
Eight changes from the last group stage game restored Ivory Coast to a full strength line-up although Salomon Kalou, who tweaked a hamstring in his team's second game of the tournament, was kept on the bench until 85 minutes had been played.
In the first half, Drogba had an early volley saved and former Leeds player Max Gradel fired over after a scramble during which the Ivorians were convinced there was a handball by an opposition defender.
On 29 minutes they were awarded a penalty when Gradel was tripped running into the area. Although Drogba's spot-kick was not badly struck, it gave the keeper a chance to save that was taken.
It took just seven minutes for the Chelsea striker to redeem himself and it was an archetypal Drogba goal. Initially given the ball by carelessness from Equatorial Guinea, he powered forwarded and then cut back inside his closest pursuer before firing the ball inside the near post.
Ivory Coast have not conceded a goal in the tournament and continued to look safe in the second half. They appeared likely to add a second when Drogba began a swift counter-attack but Gervinho's header was tipped over and the offside flag went up as well, although incorrectly.
With 68 minutes played, Drogba did double the advantage and it was with a wonderful header into the top corner after Gervinho had won a free-kick out wide.
Toure put the result beyond all doubt on 81 minutes. It was again from free-kick won by Gervinho and it was curled into the net by the Man City player; another quality goal.
Ivory Coast play the winners of the quarter-final between the other co-hosts, Gabon, and Mali. The match takes place on Wednesday with a 7pm kick-off UK time.
