Nigerian President Muhammadu Buhari
says he is not demanding "any apology from anybody" after UK Prime
Minister David Cameron labelled his country "fantastically corrupt".
Mr Cameron made the unguarded comments in a conversation with the Queen.
He is hosting an international anti-corruption summit on Thursday.
Mr Buhari's address at the anti-corruption event at the Commonwealth Secretariat in London followed a statement from his office on Wednesday, saying that he had been "deeply shocked and embarrassed" by Mr Cameron's remarks.
Asked if Nigeria was "fantastically corrupt", in an echo of the prime minister's comments, Mr Buhari responded: "Yes".
In his speech, the Nigerian leader described corruption as a "hydra-headed monster" which threatened the security of countries and "does not differentiate between developed and developing countries".
