United Nations Day for South-South Cooperation 2026

The United Nations Day for South-South Cooperation celebrates the growing solidarity, collaboration and exchange of practical solutions among countries of the Global South. It recognizes that every country has valuable knowledge, experience and innovation to share, and that progress is strongest when countries learn from one another.

In 2026, the Day is observed under the theme "Solidarity Rising: Global Alliance for Inclusive and Innovative Development." The theme highlights how South-South and triangular cooperation can help countries connect proven solutions with the partnerships, expertise and support needed to scale them.

Across the Global South, countries are increasingly sharing solutions in areas such as renewable energy, digital innovation, public health, sustainable agriculture, disaster preparedness, education and public services. These exchanges help countries adapt successful approaches to their own needs and accelerate progress toward the Sustainable Development Goals.

The 2026 observance will also mark the launch of the Global Alliance for South-South and Triangular Cooperation, a voluntary, UN-facilitated platform convened by the United Nations Office for South-South Cooperation (UNOSSC). The Alliance is designed to connect country priorities with expertise, partnerships and catalytic support, helping turn shared experience into practical action.
