Theophilus Anobaah scored the only goal of the game to give Ghana victory over Congo in their opening match at the African Nations Championship.
On 34 minutes Anobaah struck a shot which took a deflection off the back of a defender and went over the keeper's head.
In the late game on Monday, Libya beat Ethiopia 2-0 to take an early lead in their group.
Elmutasem Abushnaf and Abdelsalam Omar got the goals for them.
Congo responded well to going behind in the first game and hit the bar twice in the space of as many minutes as they pushed for an equaliser.
There were fewer chances after the break and Ghana held on comfortably.
Congo will hope the presence of Claude LeRoy, who was appointed as head coach in December and is at the tournament to support CHAN team coach Sebastian Migne, can help them improve in their remaining group games.
