In order to promote, coordinate and support South-South and triangular cooperation, the Special Unit has designed a 3-in-1 architecture through which it supports the development community. The Special Unit serves as the Secretariat for and receives policy directives from the General Assembly High-level Committee on South-South Cooperation and operationalizes these directives through its architecture. The first pillar of this architecture is the Global South-South Development Academy (GSSD Academy) – an online platform through which hundreds of Southern development solutions and experts have been identified, codified and managed. The best solutions are then showcased at the Global South-South Development Expo (GSSD Expo) – an annual United Nations system-wide event convened by the Special Unit to showcase the strongest, most successful Southern development solutions to the complex challenges facing the South today. The Special Unit facilitates the transfer of proven solutions through the South-South Global Assets and Technology Exchange (SS-GATE) – a physical and Internet-based platform through which Southern solution seekers and providers can transfer and obtain needed technology, development solutions and financing in a secure environment.
