Calls upon the Office of the High Commissioner, the international community and other concerned entities to intensify their support to African Governments through appropriate capacity-building activities, including training of relevant officers, disseminating information about refugee instruments and principles, providing financial, technical and advisory services to accelerate the enactment or amendment and implementation of legislation relating to refugees, strengthening emergency response and enhancing capacities for the coordination of humanitarian activities; 22.
