Disputes over payments at previous tournaments "had led to situations that affected badly the image of African football, with a considerable impact on team performances," he added.
Last year, Nigeria's football federation (NFF) signed an agreement with its players pledging to avoid the bonus and pay rows that have blighted past World Cup campaigns.
The Super Eagles were involved in a protracted dispute ahead of the 2013 Confederations Cup in Brazil and a bonus row also disrupted their World Cup campaign in 2014.
Similar problems have affected other African teams.
The 32 teams taking part in the June-July tournament receive $1.5 million each from FIFA in the form of a preparation fee and are guaranteed a minimum of $8 million more in prize money after the tournament ends.
