Having been part of the side which lost all three matches in 2010, the midfielder insists the squad is stronger as a unit as they prepare to face Brazil, Croatia and Mexico
Four years ago the midfielder was part of a squad that failed to collect a single point from their group matches in South Africa.
The squad's flight to Brazil was also delayed by 12 hours after the players refused to board the plane over a dispute concerning bonuses, with the Cameroon Football Federation forced to take out loans in order to broker an agreement.
Makoun, who featured in all three games in South Africa in 2010, is convinced there is a better atmosphere in the current Cameroon party and is optimistic they can escape from a group featuring hosts Brazil, Croatia and Mexico as they look to do their country proud this month.
"What happened in South Africa should not happen again," Makoun is quoted as saying in L'Equipe. "I think all who were there and will play at the World Cup in Brazil have gained experience and maturity.
"We have had four more years. There is a lot of serenity and solidarity in the squad.
"We needed this cohesion."
Cameroon face Mexico in their opening game on Friday and Makoun knows the importance of making a strong start.
"Much will depend on the first game against Mexico, it's almost a game of six points," he added.
"If we win, it puts us almost in orbit. In any case, it is important not to lose it.
"Our ambition is to pass the first round, which only happened once to Cameroon in the World Cup (in 1990)."
