Rocker/activist Bono has called for the creation of a United States of Africa, insisting a united continental identity could help the African nations to resolve their internal conflicts.

The U2 frontman - who flew to Japan to participate in a major development conference last week - has urged the country leaders in the continent to turn to the U.S. as an example of unification.

A United States of Africa "would be the dream" in the long term, Bono told Japanese newspaper Asahi Shimbun on Tuesday.

He says, "Irish people used to always have a little giggle when they would see Americans saluting their flags in schools, and then the whole lot standing there, singing the flag thing. But as you get to know a little bit more about things, you start to think, ah, there's so many different tribal groups in the United States, that to create a national identity of that size, they had to really work at this kind of patriotism."

Inspired by the European Union, the African Union was created in 2002 - but critics say the order has lacked the money needed to take effective action in the continent's conflict.

It intervened in the war-torn western Sudanese region of Darfur, but has since surrendered leadership to the United Nations in a bid to form a unified peacekeeping body.
