France has committed itself to helping establish and finance a pan-African military force capable of intervening in crises like the current conflict in the Central African Republic.
A two-day summit attended by leaders of all but a handful of African states, concluded with French President Francois Hollande pledging to help the African Union turn its plans for a rapid reaction force, agreed in principle earlier this year, into reality.
"We all agreed on the fundamental principle that it is up to Africa to ensure its own security," Hollande said.
Paris is offering to provide equipment, logistical support and advice on coordination for the force, and will seek to persuade Britain, Germany and other European Union partners to help finance the equipment and arms it will require.
"Europe can play its part," Hollande said.
"For Europe to ensure its own defence, Africa must be able to ensure its own. Our interests are linked. Terrorism knows no borders."
The summit conclusions also called for a "major international mobilisation to increase the level and predictability of financing for African peacekeeping operations".
As part of efforts to help African states create more effective military units, France has offered to providing training for 20,000 troops from the continent for five years.
Hollande said that France would have 1600 troops deployed in CAR, where sectarian violence has left hundreds dead in the last few days alone, by Saturday evening.
UN chief Ban Ki-moon praised France for being prepared to act in its former colony, saying there was am "urgent need to avoid further deterioration of the situation".
The CAR mission is France's second military operation in Africa this year.
In January, Hollande sent more than 4000 troops to Mali, where Islamist groups had seized control of much of the north of the country and threatened to advance on the capital Bamako.
