UK Prime Minister Tony Blair has urged African states to back a war crimes court to bring to justice brutal and violent former leaders.
The prime minister presented a paper on conflict resolution, whilst visiting an army training institution in Ghana's capital, Accra.
He set out specific goals that African states, in partnership with the United Nations, and Western governments, should pursue to help bring stability to the region.
In a later speech to Ghana's parliament, Mr Blair also called for a new plan that would set out specific obligations between Africa and industrialised nations.
"This should be done as a partnership between us - not aid as a handout, but aid as a hand up, to help people to help themselves."
Court
In the conflict resolution paper, Mr Blair specifically urged African states to ratify the Rome Statute of the International Criminal Court, which should come into existence in the middle of next year.
That court would have the jurisdiction to prosecute those responsible for war crimes and crimes against humanity.
Former dictators still at large include Idi Amin of Uganda, Ethiopia's Mengistu Haile Mariam and the former leader of Chad, Hissene Habre.
Mr Blair also urged the G8 group of industrialised countries to encourage African states to ratify the creation of a court of human and people's rights.
He also stressed the need to tackle the massive problem of small arms held in the continent.
There are currently 100 million such weapons in the possession of about one in six people.
They include hand guns, machine guns, hand grenades, rocket launchers, surface-to-air missiles and other lethal materials.
Ghana
Mr Blair held Ghana up as a model for the way other states can develop.
The country currently has a peace-keeping force and it has deployed troops in Sierra Leone, the Congo, the Lebanon and Kosovo.
The Staff College in Accra trains such forces, with the help of expertise from the UK and elsewhere.
Stressing the scale of the problem, Mr Blair talks of: "Entrenched and long-running conflict such as those in Angola, Sudan and Somalia."
"They have already condemned millions of people to poverty, disease and displacement and early death and are all but ignored by the developed world."
He also referred to long-running conflicts in Rwanda and Burundi.
Mr Blair is later due to visit tribal chiefs and a cocoa co-operative, in his campaign to boost fair trade in the region.
