Project aid is an integrated aid program to assist developing countries in their economic and social development. The formalities of project aid consist of identification, screening, planning, implementation, and evaluation over a period of between two and five years. The physical and human resources cooperation required for the project-aid program is considered and negotiated through demand analysis and with the needs of the recipient country in mind. In general, recipient countries provide the project site and local manpower and bear local costs, such as customs clearance, transportation, and administration, while KOICA provides materials, equipment, and technical manpower.
