国际合作体系正在发生深刻变革，援助主体正从美国和欧洲等传统援助国扩大到新兴经济体等多元主体共同参与，国际合作的主要形式正由以北方援助南方发展为主、南南合作为补充，转变为南南合作与南北合作并驾齐驱，南南合作的理念和经验甚至引领国际发展合作。新南南合作面临从南方视角构建自身发展知识和经验、促进南南国家之间平行经验的转移，以及协调南南合作与南北合作关系的挑战。在逆全球化的背景下，创新南南合作的模式，为全球治理提供更多公共产品，为全球性的问题提供新的思路和解决方案，积极塑造国际合作体系成为南南合作的新使命。
The international cooperation system is undergoing profound changes. The actors of aid system diversified from the previously dominant traditional donors such as the United States and European countries to emerging economies and other multilateral organizations. The main form of international cooperation which was mainly driven by the North-South cooperation and supplemented by the South-South cooperation has been changed. South-South cooperation is becoming equally important to North-South cooperation. The concept and modalities of South-South cooperation even has been leading international development cooperation. An apparent example is that the OECD DAC decided to introduce the broader concept of “Official Total Support for Sustainable Development （TOSSD）”，which is undoubtedly influenced by the Chinese approach of development cooperation by combining aid，trade and investment. The new South-South cooperation faces the challenge of building up its own development knowledge and experience from a southern perspective，promoting the transfer of parallel experiences between South and South countries，and coordinating the South-South cooperation and North-South cooperation. In the context of counter-globalization，new South-South cooperation has to shoulder the new responsibility to provide more public goods for global governance，to provide new ideas and solutions for global problems，and to actively shape the international cooperation system.
