United Nations Day for South-South Cooperation
<p>On 12 September 1978, delegations from 138 states gathered in Buenos Aires and adopted, by consensus, a plan with a cumbersome title and a radical premise. The Buenos Aires Plan of Action for Promoting and Implementing Technical Cooperation among Developing Countries argued that the nations of the Global South had a great deal to teach one another, and need not always wait on expertise flowing down from the wealthy North. It is that date and that idea the United Nations Day for South-South Cooperation now marks each 12 September. The day celebrates a model of partnership built on solidarity between countries facing comparable problems rather than charity from those who have escaped them.</p>

<p>The roots of South-South cooperation run back to the era of decolonisation, when dozens of new states emerged from European empires and found themselves politically independent but economically constrained. A defining early moment was the Asian-African Conference held at Bandung, Indonesia, in April 1955, where leaders including Indonesia’s Sukarno and India’s Jawaharlal Nehru set out principles of mutual respect and non-interference. Bandung helped give rise to the Non-Aligned Movement, formally founded in 1961, and to the Group of 77, the coalition of developing countries established at the UN in 1964. It was the G-77 that chiefly carried the banner of cooperation among developing nations through the 1960s and 1970s.</p>
<p>The leaders most associated with the movement, among them Nehru, Egypt’s Gamal Abdel Nasser, Yugoslavia’s Josip Broz Tito and Tanzania’s Julius Nyerere, shared a conviction that genuine independence required economic self-reliance and that the countries of the South could build it together. The Buenos Aires conference of 1978 turned that conviction into an agreed programme. The plan it produced became the foundational document of what is now called South-South cooperation.</p>
<h2 id="a-history-with-a-moving-date">A history with a moving date</h2>
<p>The observance itself has a more tangled chronology than most. The first commemoration took place in December 2004, on a date that did not correspond to the Buenos Aires anniversary at all. A few years later, in 2011, the United Nations General Assembly moved the observance to 12 September so that it would fall precisely on the anniversary of the 1978 plan’s adoption. The shift mattered: it tied the day firmly to a documented historical event rather than an arbitrary slot in the calendar, and it reflected a wider effort to give the cause greater institutional weight.</p>
<p>That effort is visible in the machinery the UN has built around the idea. The United Nations Office for South-South Cooperation, which traces its origins to a special unit established within the development programme in the 1970s, now coordinates work across the system. In 2019 a second major summit, often referred to as BAPA+40, returned to Buenos Aires to mark forty years since the original plan and to assess how far the movement had travelled. The answer was: a remarkably long way, from a hopeful aspiration among a handful of newly independent nations into a dense network of agreements and trade.</p>
<p>The scale of that change is best captured in trade figures. In 1978, commerce between developing countries was a minor sliver of world trade; by the 2010s, South-South trade accounted for a substantial and growing share of all global exchange, with countries such as China, India and Brazil emerging as major partners and investors across Africa, Asia and Latin America. The flow of money has been joined by a flow of expertise. Brazil’s agricultural research body has shared techniques for farming tropical savannah with African nations facing similar soils; Cuba has dispatched doctors and trained medical students from across the developing world; India has run technical training programmes for officials from dozens of partner countries. Each example illustrates the founding insight of 1978, that capability worth exporting is not the monopoly of the rich.</p>

<p>The strength of South-South cooperation lies in its fit. Because the partners often share similar climates, comparable levels of development and overlapping histories, the solutions they exchange tend to transplant cleanly in a way that imported Northern models frequently do not. A drought-resistant farming technique developed in one semi-arid country is more likely to work in another than a system designed for temperate Europe. Low-cost healthcare delivery, community-led infrastructure and practical training pass between developing regions precisely because they were built for those conditions in the first place.</p>
<p>There is a political dimension too. By pooling experience and speaking with a more unified voice, the countries of the Global South gain leverage in international forums where economic policy and global governance are decided. Cooperation lets them reduce dependence on external aid and take greater command of their own development. Confronting shared burdens such as poverty, inequality and environmental damage, they can trade best practice and hard-won lessons directly, sidestepping the slow and sometimes ill-suited channels of traditional assistance. The day exists to keep this case in view and to celebrate its results.</p>
<h2 id="how-it-is-marked">How it is marked</h2>
<p>The observance lives chiefly in conferences, forums and policy discussions hosted by UN bodies, governments and development organisations. These gatherings showcase concrete partnerships, from agricultural training programmes and infrastructure projects to exchanges in healthcare, education and disaster preparedness, and publish reports and case studies meant to encourage replication elsewhere. Universities and research institutes in the Global South hold seminars on the theory and practice of cooperation, while regional bodies use the date to renew commitments and announce new joint ventures.</p>
<p>It is, admittedly, a day better known in development and diplomatic circles than to the general public. Yet within those circles it carries real significance as a marker of progress and shared ambition. Its themes connect to the broader work of the organisation, sitting naturally alongside <a href="/specialdate/united-nations-day/">the wider United Nations Day</a> that celebrates the institution as a whole, and overlapping in spirit with the human-development concerns marked by <a href="/specialdate/united-nations-international-day-of-persons-with-disabilities/">the International Day of Persons with Disabilities</a>, since inclusive development is central to what cooperation aims to achieve. The same network of observances includes <a href="/specialdate/united-nations-public-service-day/">the United Nations Public Service Day</a>, a reflection of how much South-South cooperation depends on competent, well-run public institutions to carry it out.</p>
<h2 id="symbols-and-the-partnership-of-equals">Symbols and the partnership of equals</h2>
<p>The day’s defining image is partnership between equals rather than the familiar hierarchy of donor and recipient. One concept frequently highlighted is triangular cooperation, in which a developed country or an international organisation funds and supports collaboration between two or more developing nations, blending Northern resources with Southern expertise. The arrangement neatly resolves a recurring tension: the South often holds the most relevant knowledge while the North holds the deeper pockets, and triangular projects let each contribute what it has. The underlying message is that knowledge and capability are spread across the whole world, and that nations once seen mainly as objects of aid are themselves sources of innovation and assistance.</p>
<p>The vocabulary of the movement matters, too. The very phrase “Global South” is a deliberate alternative to older, more loaded terms such as “Third World” or “developing countries”, which framed nations chiefly by what they lacked. By speaking of South and North as horizontal directions rather than rungs on a ladder, the language insists on a relationship of peers. That reframing is not mere diplomacy; it shapes how projects are designed, who sets their priorities, and whose expertise is treated as authoritative, and it is precisely this shift in posture that the 12th of September is meant to honour.</p>

<ul>
<li>The Buenos Aires Plan of Action was adopted by consensus by 138 states in 1978, a striking show of unity at a conference convened specifically to give developing countries a programme of their own.</li>
<li>The day was first observed in December 2004 and only moved to 12 September in 2011, so for its first years the celebration did not coincide with the anniversary it now marks.</li>
<li>The intellectual groundwork was laid not in 1978 but in 1955 at the Bandung Conference, whose principles seeded both the Non-Aligned Movement and the Group of 77.</li>
<li>In 2019 a second summit, BAPA+40, returned to Buenos Aires four decades on, by which point trade and technical exchange among developing countries had grown into one of the most dynamic parts of the global economy.</li>
<li>The term “Global South” deliberately replaced older labels such as “Third World”, a phrase coined in 1952 by the French demographer Alfred Sauvy, who borrowed it from the “third estate” of pre-revolutionary France.</li>
</ul>
<h2 id="a-closing-reflection">A closing reflection</h2>
<p>There is a quiet dignity in the premise behind this day, easy to miss because it is now so widely accepted. For much of the twentieth century, “development” was assumed to travel in one direction, from those who had to those who lacked. The countries that met in Buenos Aires in 1978 rejected that geometry, insisting that a nation could be poor in capital yet rich in usable knowledge, and that the South had as much to offer itself as it could ever receive from elsewhere. That reframing, more than any single project, is what the 12th of September is really for.</p>
