联合国各组织根据2009年内罗毕成果文件和其他相关文件,对南南发展合作作出如下定义:两个或多个发展中国家通过交流知识、技能、资源和技术专长,并通过区域和区域之间的合作行动,包括建立由各国政府、区域组织、民间社会、学术界和私营部门参加的伙伴关系,从而实现其单独或集体发展的过程。由于发展中国家绝大部分都处于南半球和北半球的南部,故称这一合作为南南合作。 Based on the 2009 Nairobi outcome document and other relevant documents, the United Nations organizations have defined South-South development cooperation as follows: Two or more developing countries, through the exchange of knowledge, skills, resources and technical expertise, and through interregional and regional Cooperative actions, including the establishment of partnerships involving Governments, regional organizations, civil society, academia and the private sector, in order to achieve their own or collective development. Since most developing countries are in the southern hemisphere and the southern hemisphere, they call this cooperation a South-South cooperation.
