O'Neill says Africa trip with Bono to energise development

US Treasury Secretary Paul O'Neill said his upcoming Africa trip with U2 lead singer Bono is designed to help start reversing 50 years of poor performance in development aid.

"We need a change in performance realisation from what's gone before... we've got to produce results," O'Neill said in a press briefing ahead of his two-week, four-nation trip to Africa.
