Section five concludes and discusses potential next steps. This report has been peer-reviewed by debt management experts and World Bank staff, and is being submitted to the authorities of Guinea-Bissau for their review and comment prior to finalization. The final mission report will be transmitted to the authorities for use and disclosure at their sole discretion.
