United Nations Day for South-South Cooperation 2027

Date and official background

The annual date is 12 September. The 2027 occurrence follows that fixed annual rule. No unannounced 2027 theme or event programme is assumed. See the official source for background and resources.

The General Assembly endorsed the day through resolution A/RES/58/220. Its current annual date, 12 September, commemorates the adoption of the Buenos Aires Plan of Action in 1978. Earlier arrangements used a different date, so current official sources should guide calendar planning. A 2027 theme or event programme has not been verified.

Follow-up and related dates

A useful follow-up is a short record of what the group learned and the questions it wants to pursue. Where a new collaboration is proposed, identify what further consultation, resources and decisions would be required. Do not describe an introductory conversation as an agreement already reached.

Keep the day separate from a particular conference or anniversary event. A programme held near 12 September may have its own venue, registration and dates. When sharing a previous edition’s material, retain its year and explain why it remains useful rather than presenting its arrangements as the next official programme.

Related dates include International Day of Cooperatives and World Environment Day. Each has its own identity and purpose.

If comparing project results, check whether the measures and time periods are comparable. Explain what was reported by the partners and what you can independently conclude. A useful discussion includes uncertainties and learning needs alongside examples that appear to have worked well.

Ideas for universities, schools and organisations

The following are original editorial planning suggestions to adapt to your audience, rather than an official programme.

• Study a specific partnership. Choose an official case study and identify the countries, organisations and communities involved. Record what the project set out to do and what evidence of results is available.
• Map knowledge exchange. Ask what each partner contributed and what had to be adapted to local circumstances. Avoid assuming that a solution can simply be copied from one setting to another.
• Invite a focused conversation. Give a relevant researcher or practitioner a clear brief and time to prepare. Include questions about limitations and lessons as well as successes.
• Review a public claim. Compare a project’s stated ambition with an account of work already completed. Explain the difference between a launch, a pilot and a wider implemented programme.

Planning and participation

An employer can explore a partnership connected with its actual area of work, while a school can investigate how international cooperation is described in different sources. Explain unfamiliar terms and keep any comparison grounded in named places and dated evidence. A map or a single statistic cannot tell the whole story.

For a joint event, agree each organisation’s role and how contributions will be credited. Give participants a chance to review descriptions of their work and avoid framing one partner only as a recipient of help. Check whether images and quotations can be reused for the proposed audience.
