Ahmed was speaking after a 10 hour CAF executive meeting held behind closed doors in the Ghanaian capital.
In October, CAF President Ahmad Ahmad visited Yaounde for a meeting with Cameroon President Paul Biya just days after CAF deferred the final decision on the hosting of next year's AFCON. Morocco replaced Kenya as hosts.
"Caf reiterates that Cameroon remains a serious candidate to organize a future edition of Afcon, and acknowledges that Cameroon has mobilized significant resources and worked tirelessly to host Afcon 2019".
"The final decision will be taken in late November after the last inspection visit which will involve audit firm Roland Berger".
Cameroon, who lifted the trophy past year after beating Egypt 2-1 in the final, were initially named as hosts for a 16-team event, only for CAF to confirm an increase in participants in July 2017 during a symposium held in Morocco.
Morocco is the favourite to take over the hosting of the expanded 24-team tournament, which is being held from June 15-July 13.
Increasing the field of the Nations Cup and switching its hosting to mid-year were among reforms announced last year in a major overhaul of the African game.
Morocco may be the favourite to rescue CAF this time but lost the tournament three years ago after it threatened to place travel restrictions on fans travelling from West African countries affected by that year's deadly Ebola outbreak.
