In an interview published today, Jean-Yves Le Drian said he felt "disgust" and "betrayal" when he received a leaked UN report in July last year alleging soldiers dispatched to the country to restore order after a 2013 coup had sexually assaulted kids in exchange for food.
"When a French soldier is on a mission, he is France," the minister told the JDD weekly.
"If one of them has committed such acts, they must immediately give themselves in."
UN rights investigators conducted a probe into the allegations in the spring of 2014, and a UN employee later turned the report over to French authorities because he felt his bosses had failed to take action.

"It is naturally available to the courts, which are tasked with conducting the judicial probe," he said.
"Since the alleged events, most soldiers have left that theatre of operations, but that must not stop the courts from doing their job swiftly."
According to the JDD, which saw a copy of the leaked UN report, the six children testifying against the soldiers have given very precise descriptions of tattoos and nicknames.
But a French judicial source said last week that of the 14 soldiers implicated in the probe, only a few had actually been identified.
"One of the children interviewed said that he had seen his friend, aged 9 or 10, with 2 soldiers from Equatorial Guinea," Donovan told AFP by e-mail.
