Mr Macron hit out at "the hypocrisy, particularly on the African continent" that denied the Ukraine conflict was a war.

Some African countries have held back from outright criticising Russia's aggression in Ukraine. In March, 17 African countries abstained in a UN vote to condemn the invasion.

He also said that the only solution to Cameroon's Anglophone crisis is decentralisation: "It is through this political process of dialogue and reform that a lasting solution can be found," the privately-owned Journal du Cameroun website quoted Mr Macron as saying.

He was speaking alongside Cameroonian President Paul Biya in Yaoundé.

According to Journal du Cameroun, the two leaders also discussed "jihadist threats in northern Cameroon with Boko Haram", and the conflict between the Cameroonian forces and armed separatist groups.

The French president began a three-country tour of Africa on 25 July, with food security, militant violence and France's relation with the continent expected to dominate his talks with African leaders.
