CAF president and FIFA vice president Issa Hayatou said he saw nothing wrong with the payment made before the confederation held a congress in the Angolan capital Luanda in January 2010.
Qatar won the right to host the 2022 World Cup later the same year at a controversial FIFA vote now under investigation by Swiss authorities.
Paris-based Jeune Afrique magazine asked Hayatou about the donation from Qatar.
"The Qataris gave it to us to be able to show their plan (for the 2022 World Cup) during the congress."

Hayatou insisted he had not expected other candidates, including the United States and Australia, to pay for a similar privilege.
"Not necessarily. We didn't ask Qatar to do it. They proposed it. We did not ban the other candidates from taking part in the presentation," he was quoted as saying, while also denying that it was a bid to buy African votes.
Hayatou also denied there was any corruption in the vote which gave the 2010 World Cup to South Africa.
Asked about the payment, a CAF spokesman told AFP that Qatar "wanted to have this privilege exclusively" to make its presentation.
"A proposition was made to the executive committee which adopted it. Qatar presented its bid. The money was paid to CAF and is noted in the confederation's accounts," the spokesman added.
Hayatou also denied any knowledge of bribes paid to secure the 1998 and 2010 World Cups.
US investigators believe that a $10 million payment made by South Africa to a disgraced Caribbean football official was a bid to buy votes. South Africa has strongly denied any wrongdoing.
"Fixed by who?" said Hayatou. "All I can tell you is that we, the Africans, carried out a draw so we did not give the impression we were for one or the other candidate.
