Ivory Coast played out a pulsating draw game with Togo in the first game in Group on Monday.
Paris Saint-Germain defender Serge Aurier came close to breaking the deadlock with two minutes remaining, heading a cross narrowly wide in a match that failed to sparkle.
The result maintained a trend of stalemates in the 2017 tournament, which kicked off two days ago, with four of the first five matches failing to produce a winner.
The best for the title-holders came after 10 minutes to Jonathan Kodjia, a gangling striker with English second-tier outfit Aston Villa.
Salomon Kalou, a survivor of the 2015 Cup of Nations-winning team, did the spadework by dribbing past several red-shirted Togolese before pushing the ball into the box.
Togo had an opportunity to score the first goal before the break but Sylvain Gbohouo in post for Ivory Coast saved the situation for the defending champions.
It was back and forth in the second half, but both sides failed to get the ball at the back of the net, as the game ended 0-0.
In the other Group C game, Dr Congo stunned Morocco courtesy a beautiful strike from Junior Kabananga in the second half.
The Congolese were reduced to 10 men with eight minutes left when a wild challenge from Joyce Lomalisa earned a second yellow card.
Morocco did everything they could but they couldn’t get the needed equalizer.
