Nairobi, a New Assembly Hall and Africa’s Place in Global Decision-Making

Nairobi, 12 May 2026. United Nations Secretary-General António Guterres and President William Ruto on Monday broke ground on a new 1,600-seat Assembly Hall at the United Nations campus in Gigiri, marking a defining step in Nairobi’s growing role as a global centre for multilateral diplomacy.

The ceremony also marked the inauguration of the first completed phase of a nearly USD 340 million expansion of the United Nations Office at Nairobi (UNON) conference facilities. Approved by UN Member States through the General Assembly 18 months ago, the project will increase delegate seating capacity at UNON from 2,000 to 9,000 and expand the number of meeting rooms from 14 to 30. Once complete, the expansion will position Nairobi as the third-largest United Nations hub globally, after New York and Geneva.

The scale of the investment is significant. Yet, the message from both leaders went well beyond infrastructure. At the heart of the ceremony was a broader question: what does it mean for the only United Nations headquarters in the Global South to grow at a moment when Africa’s economic, demographic and diplomatic weight is also rising?

For President Ruto, the expansion strengthens Nairobi’s position as a premier hub for international diplomacy and global convening. He noted that the Government of Kenya has committed USD 1.1 billion in complementary investments, including roads, street lighting, the regeneration of the Nairobi Rivers, ICT infrastructure and the operationalisation of the UN One-Stop Shop. These investments will strengthen the wider ecosystem around the UN complex and support Kenya’s ambition to host major global summits.

The President’s message also carried a broader strategic argument. Africa, he said, should not be understood through the language of aid or loans alone, but through its ideas, solutions and investments.

Reforming the systems that shape development

The convergence between the two leaders was on the reform of the international financial architecture. Both spoke directly about the need to ensure that African countries can access affordable finance for development, climate action and long-term economic transformation.

President Ruto highlighted Kenya’s proposals on the New African Financial Architecture for Development, aimed at addressing debt vulnerabilities and expanding access to concessional financing for African economies. He also pointed to Kenya’s National Infrastructure Fund as part of the country’s efforts to mobilise financing at scale for national development priorities.

The Secretary-General echoed these concerns, noting that African countries continue to pay far higher interest rates than developed countries, even where their financial positions and development prospects are sound. He linked this imbalance to the historical exclusion of African countries from the creation of key global governance institutions in 1945.

For the Secretary-General, reform is not only a technical question, it is a matter of justice. He called for changes across the international system, including the multilateral development banks, the International Monetary Fund, the World Bank and the UN Security Council. Permanent African representation on the Security Council, a fairer share of quotas in the international financial institutions, and expanded access to affordable development finance were presented as part of a single call: that Africa must have a meaningful voice in the institutions that shape global decisions.

Earlier in the day, the Secretary-General met the UN Country Team in Kenya, where he reflected on the future direction of UN support to the country. He said the next United Nations Sustainable Development Cooperation Framework should become a prototype for a new kind of partnership.

He linked this to Africa’s wider development transformation. Kenya’s and Africa’s future, he said, requires sustained investment in education, health, infrastructure, regional markets, value addition, digitisation and artificial intelligence. It also requires, in his view, moving beyond economic patterns inherited from the colonial era, patterns in which infrastructure and production systems were too often organised around extraction rather than the building of strong national and regional economies.

UN Resident Coordinator in Kenya, Dr Garry Conille, echoed that framing. He noted that as the UN works with the Government of Kenya on the next Cooperation Framework, the focus should shift from asking what Kenya needs from the UN to asking where Kenya intends to lead, and how the UN can best support that leadership in alignment with the country’s long-term development ambitions. Dr Conille observed that Kenya already holds many of the foundations needed to drive sustainable development: a strong civil society, robust democratic institutions, strategic geography, regional economic influence, a young and skilled population, and a proven track record of innovation.

Nairobi, a stronger hub for multilateral diplomacy

The Nairobi expansion also carries a strong environmental dimension. The new Assembly Hall will be powered by onsite solar energy and is projected to reach energy neutrality by 2029. The wider Gigiri complex, located on 140 acres generously donated by the Government of Kenya in 1972 and 1975, already hosts more than 4,000 personnel and 88 United Nations offices.

When complete, the new facilities will allow Nairobi to host larger intergovernmental meetings, major conferences and high-level diplomatic engagements. The significance of the project, however, lies not only in its capacity. It also signals a shift in how — and where — global decision-making takes place.

From Gigiri, the message was clear. Nairobi is not simply expanding as a conference venue, it is becoming a stronger platform for Africa’s voice in multilateral affairs, climate action, sustainable development and global governance reform. The groundbreaking of the new Assembly Hall, therefore, marks more than the start of construction. It reflects a growing recognition that the future of multilateralism must be more representative, more balanced and more closely connected to the regions whose voices have historically been less heard in the institutions where global decisions are made.
