Bono met Merkel at the chancellery to press his call for the continent to remain high on the agenda of the world's leading industrial countries. Germany, which chairs the G-8, will host their annual summit in the Baltic sea resort of Heiligendamm.
Merkel pledged that Africa will play "an outstanding role," with a focus on issues such as improving the climate for investment, a government spokeswoman said on customary condition of anonymity.
Bono has echoed that call, saying at January's annual meeting of the World Economic Forum: "Africa is this magical, extraordinary continent and we've got to start describing it more as an opportunity than a burden."
The 46-year-old Irish rocker is co-founder of the organization DATA, or Debt, AIDS and Trade in Africa, which seeks to raise awareness for Africa.
