Understanding South-South Cooperation

South-South cooperation (SSC) refers to the exchange of resources, technology, knowledge, and policy experience among countries in the Global South — that is, developing and emerging economies primarily in Asia, Africa, and Latin America. It stands in contrast to traditional North-South development models, where wealthy nations provide aid or investment to poorer ones.

The D-8 is one of the most prominent institutionalized expressions of South-South cooperation, bringing together eight large developing nations under a formal organizational structure with a permanent secretariat and regular summitry.

How D-8 Relates to Other Global Institutions

The United Nations and the SDGs

All eight D-8 members are UN member states and signatories to the Sustainable Development Goals (SDGs). The D-8 has aligned much of its cooperative agenda with SDG targets, particularly those related to poverty reduction (SDG 1), decent work and economic growth (SDG 8), and partnerships for development (SDG 17). This alignment gives the D-8's work legitimacy within the broader multilateral system and creates reporting frameworks that member states can use to track progress.

The G20

Several D-8 members — notably Indonesia, Turkey, and Nigeria (as an invited participant) — participate in G20 processes. This creates a two-way channel: D-8 positions can be introduced into G20 discussions, and G20 commitments on development finance and climate can be channeled back into D-8 implementation agendas. However, not all D-8 members have G20 seats, which limits the bloc's direct influence in that forum.

BRICS

The recent expansion of BRICS is particularly relevant for the D-8. With Egypt and Iran joining BRICS in 2024, two D-8 members now participate in the influential emerging-market grouping. This creates potential for policy synergies — particularly around de-dollarization, alternative payment systems, and development financing — between the two blocs.

OIC and ECO

The D-8 overlaps significantly with the Organisation of Islamic Cooperation (OIC), of which all eight member states are members. The D-8 has historically positioned itself as the economic complement to the OIC's broader political and cultural mandate. Similarly, Iran and Turkey are members of the Economic Cooperation Organisation (ECO), creating additional multilateral threads.

What Makes the D-8 Distinctive?

In a landscape crowded with multilateral institutions, the D-8 occupies a specific niche:

  • Size and scale: Unlike many regional groupings, D-8 members are globally significant economies with large populations — giving the bloc real weight.
  • Developing-nation focus: Unlike the G20, which blends developed and developing economies, the D-8 is exclusively a developing-nation platform.
  • Economic rather than political: Unlike the OIC, the D-8's mandate is explicitly economic, reducing friction from politically contentious issues.
  • Cross-regional: Spanning Asia, Africa, and Europe/Eurasia, the D-8 has a genuinely global footprint that purely regional blocs lack.

Challenges in Global Positioning

The D-8 faces the perennial challenge of multilateral organizations: member states have divergent national interests, and the bloc lacks enforcement mechanisms to compel compliance with agreed frameworks. Geopolitical tensions — such as sanctions on Iran — can also constrain what the bloc can achieve collectively.

Nonetheless, as global governance becomes more contested and developing nations seek greater agency, the D-8's model of South-South economic cooperation is more relevant than ever.
