Bono travelled to Lesotho yesterday as part of his tour of six African countries.
Reuters reports that the singer backed a new initiative in the country which will give textile workers access to AIDS testing and treatment.
Speaking on his arrival in the capital, Maseru, Bono said that Lesotho was a microcosm of the debt, AIDS and trade problems facing Africa.
Bono said he would campaign for wealthy countries to open their markets to more African-made clothing.
His African visit, on which he is accompanied by corporate executives, is to show the progress in treating people with HIV-AIDS and highlight the need for trade growth and the campaign to cancel African debt.
Bono spoke of his anger at the fact that Lesotho had not benefited from debt cancellation.
"The reason Lesotho has not received debt cancellation is because it has been disciplined, it has been punished for the fact that it has been a good borrower in the past and has paid back its debts, so we want to address that," he said.
