Africa needs to "go on the offensive" and show the political will to defeat corruption, the head of the African Development Bank has said.
Corruption damages economic growth, the ADB head said
Donald Kaberuka, the bank's president, said such a renewed effort was vital to boost economies and to encourage more investment from overseas.
He made his comments on the sidelines of a business conference in Rwanda.
Rwanda's former finance minister, he is credited with leading the rebuilding of its economy since the 1994 genocide.
Mr Kaberuka has been president of the African Development Bank (ADB) for eight months.
"Corruption damages economically, reduces the opportunities for economic expansion and it delays the day investors can have greater confidence in Africa," he told the Reuters news agency.
Mr Kaberuka has called for the ADB to be at the centre of development issues on the continent, alongside the African Union's New Partnership for Africa's Development.
"We have embarked on increasing the quality of our operations, to ensure that the development outcomes are effective and that they are actually delivered on the ground," he said.
