South-South cooperation is an invaluable complement to North-South cooperation.

Collaboration in which traditional donor countries and multilateral organizations facilitate South-South initiatives through the provision of funding, training, and management and technological systems as well as other forms of support is referred to as “triangular cooperation”.

Countries at similar levels of development, and that share similar philosophies of development, are particularly well placed to help each other.

Much of the growing cooperation is between middle-income and low-income countries. Middle-income countries are both donors and recipients of aid, giving them a unique perspective on the development process. They play an increasingly important role in the international development architecture, as donors, trading partners and sources of expertise.
