UN: A New Secretary‑General in a Fragmented World
Victor Ângelo
The United Nations Security Council will next week enter a new phase in selecting the next Secretary‑General. The vote will be informal, and each candidate will receive one of three assessments: encouragement, discouragement, or no opinion. This step unfolds against an international landscape marked by political fragmentation, strategic rivalry, and a growing scepticism about the capacity of multilateral institutions to respond to shared global challenges. The successor to António Guterres will inherit not only an agenda crowded with crises, but also the responsibility of demonstrating that global problems can only be confronted through some degree of collective cooperation.
For decades, and until the early years of this century, there existed a minimal consensus around the need for a shared international development agenda. That spirit animated the Millennium Development Goals (2000) and re‑emerged, with greater ambition, in the Sustainable Development Goals (2015). Today, however, that consensus has weakened. The rhetoric of cooperation persists, but the political action that once sustained it has been profoundly eroded.
Three structural factors help explain this deterioration.
The first is the intensification of competition among major powers. Development, infrastructure, technology, and global governance have ceased to be mere domains of cooperation; they have become instruments of power. The most influential states now compete over norms, markets, strategic dependencies, and institutional spaces. The Security Council — which should be the principal forum for building compromise — has proved increasingly unable to produce the necessary and lasting agreements.
China seeks to occupy this space through its global initiatives on Development, Security, Civilisation and, since September 2025, Global Governance, recently complemented by the creation of the World Artificial Intelligence Cooperation Organisation (WAICO). These initiatives follow the Belt and Road framework launched by Xi Jinping in the previous decade. China’s official vocabulary is multilateralist, yet in practice these proposals compete with Western initiatives — such as the G7 Partnership for Global Infrastructure and Investment (2022) — and with the UN itself. What is at stake is not merely the financing of roads, ports, digital networks, or energy systems, but the definition of standards, the establishment of financing criteria, the shaping of political choices, and the moulding of the international environment in which developing countries make decisions.
The second factor is the governance of technology. Robotics and artificial intelligence can free labour from repetitive or dangerous tasks, accelerating progress in health, education, science, and public administration. But without common rules and shared oversight mechanisms, these technologies risk concentrating economic and political power, deepening inequalities, and reducing the autonomy of entire societies. The Sino‑Western dispute over AI norms makes the creation of multilateral forums capable of setting minimum standards even more urgent.
The third factor is the digital transformation of societies. Social media have profoundly altered how citizens perceive the world, relate to one another, and participate in public life. The philosopher Byung‑Chul Han — an exceptionally original thinker and recipient of the Princess of Asturias Award for Communication and Humanities (2025) — argues that digital capitalism fosters an individualism centred on self‑exposure and egocentrism. This “society of the self” erodes empathy and generates indifference towards collective causes: distant poverty, other people’s wars, the climate crisis, or institutional fragility. A kind of civic anaesthesia has taken hold. Added to this is the impact of transnational disinformation, which crosses borders at digital speed and shapes public perceptions, political decisions, and even the legitimacy of multilateral institutions.
Faced with this landscape of public apathy and interstate rivalry, the next Secretary‑General will need to define priorities that are both realistic and politically sustainable. Even before doing so, he or she must redesign the UN’s relationship with the expanding ecosystem of regional organisations and cooperation platforms led by Global South states. Bodies such as the African Union, ASEAN, CELAC, the Arab League, the Shanghai Cooperation Organisation, BRICS+, WAICO, and the Belt and Road Initiative now shape strategic decisions on security, infrastructure, technology, and finance. They are not merely complementary forums: they are instruments of political and economic influence that sometimes compete with the UN’s universal coordinating role. The challenge for the next SG will be to cooperate with these entities without allowing them to replace the UN’s normative and universal function, ensuring that institutional fragmentation does not become normative fragmentation.
The first priority should be a proposal for reform of the Security Council. Without a composition more representative of contemporary geopolitical realities, without greater presence of emerging powers, and without some limit on the paralysing effect of the veto, the Council will continue to lose legitimacy and effectiveness. Bringing it closer to the General Assembly and making it more accountable to the international community will be equally essential.
The second priority should be the protection of multilateral mechanisms that still produce globally beneficial consensus: public health, food security, climate action, humanitarian assistance, migration, sustainable development, and conflict prevention. These are areas where cooperation remains possible and where the UN retains clear added value.
The third priority will require particular attention to the definition of minimum standards for technological governance, especially in the field of artificial intelligence. The aim is not to impose a single model, but to avoid normative fragmentation that leaves the most vulnerable countries at the mercy of private interests or strategic pressure from major powers.
Rebuilding trust means identifying concrete areas where cooperation remains viable, creating incentives for it to prevail over rivalry, and demanding greater political responsibility from those who weaken institutions serving common interests. It also requires clearer rules for digital platforms, whose impact on public opinion and democratic quality can no longer be treated as a secondary matter.
The choice of the next Secretary‑General matters, but it will not be sufficient. Equally decisive will be the quality of the team that accompanies him or her, its independence from the pressures of its countries of origin, and its ability to build bridges without becoming captive to any bloc. The central challenge is not to restore a lost faith in international solidarity, but to construct more modest, pragmatic, and persistent forms of collaboration in a world where interests diverge, power is more dispersed, and trust is becoming an increasingly scarce resource.
