The Fragmentation of Global Governance: Challenges from Multilateralism to a Multipolar Order

The multilateral governance system established since the end of World War II — anchored by the United Nations, the World Bank, the World Trade Organization, and the World Health Organization — is facing the most profound legitimacy crisis since its founding. The return of great power competition, the failure to supply global public goods, the disruption of existing rules by emerging technologies, and the dissatisfaction of developing countries with institutional representation are eroding this rules-based international order from multiple dimensions. Over the past five years, I have had the privilege of engaging in in-depth dialogues with eight world-leading scholars — from Nobel laureates Robert Aumann and Robert Wilson, to global health law authority Lawrence Gostin, inequality research pioneer Branko Milanovic, capital legal coding theorist Katharina Pistor, big historian David Christian, negotiation theorist Barry Nalebuff, and trend forecasting expert Mauro Guillen. These conversations, spanning economics, law, history, and public health, have allowed me to examine a central question from multiple perspectives: Why is global governance fragmenting? Can we rebuild effective international cooperation in the multipolar era?

I. The Pathology of Fragmentation: Four Structural Crises

The fragmentation of global governance is not the product of a single event but the result of four overlapping structural crises. Understanding these deep-rooted causes is a prerequisite for exploring remedies.

The first crisis is the deficit of institutional representation. The basic architecture of the current multilateral system was designed between 1944 and 1945 — when the center of gravity of the global economy lay on both sides of the North Atlantic, and the five permanent members of the UN Security Council reflected the power configuration of the World War II victors. Eighty years later, the global economic center of gravity has shifted significantly eastward and southward: in purchasing power parity terms, China's GDP has surpassed that of the United States, India ranks third, and the African continent possesses the world's youngest demographic structure and the fastest urbanization rate. Yet the composition of the Security Council has never substantively changed, and the voting rights allocation at the International Monetary Fund still heavily favors Europe and America. As I discussed in my dialogue with Professor Milanovic, this gap between institutional design and power realities not only undermines the legitimacy of multilateral institutions but also gives rising powers the motivation to establish "parallel orders" — from the Asian Infrastructure Investment Bank to the New Development Bank of the BRICS nations, the emergence of alternative institutions is a direct reflection of the existing system's representational deficit.^[1]

The second crisis is the failure to supply global public goods. The fundamental rationale for global governance is to address transnational problems that no single country can tackle alone — pandemics, climate change, systemic financial risks, and cybersecurity. However, the COVID-19 pandemic brutally exposed the severe inadequacy of the multilateral system in providing global public goods. In my dialogue with Professor Gostin, his criticism of the World Health Organization was particularly incisive: the WHO was slow in communicating information during the early stages of the pandemic, lacked independent investigative authority, was unable to bind member states to information transparency obligations, and was powerless to coordinate the equitable distribution of global vaccines. Professor Gostin pointed out that the WHO's annual budget is less than that of a single large American teaching hospital — meaning the public health safety net for all of humanity commands far fewer resources than a single city's medical institution. When the moment of greatest need for multilateral cooperation arrives, the multilateral system is at its most fragile.^[2]

The third crisis is the retreat of legal globalization. Over the past three decades, legal globalization — the convergence of legal rules driven through international treaties, bilateral investment agreements, and international arbitration mechanisms — has been an important pillar of global governance. However, Professor Pistor raised a deeply insightful point in our dialogue: the primary beneficiaries of legal globalization have been multinational corporations and financial capital with legal expertise, not ordinary citizens. Her analysis of the "legal coding of capital" — the combination of contract law, corporate law, trust law, and bankruptcy law to transform ordinary assets into legally protected capital — is essentially a strategy of leveraging legal globalization to maximize private interests. When this "legal globalization in the service of capital" provokes pushback from an increasing number of countries, legal globalization itself loses political legitimacy. In recent years, the questioning of the international investment arbitration system, antitrust actions against transnational technology giants, and the emphasis on data sovereignty by various countries are all signals of the retreat of legal globalization.^[3]

The fourth crisis is the vacuum in technology governance. Artificial intelligence, quantum computing, synthetic biology, and space commercialization — these emerging technologies that are reshaping the conditions of human existence operate almost entirely in a blank space of international governance. Existing multilateral institutions were designed for twentieth-century problems: the United Nations handles war and peace, the WTO handles trade disputes, the WHO handles pandemics — but no institution possesses the mandate or capacity to regulate cross-border AI systems or coordinate export controls on quantum technologies. As Professor Guillen warned in our dialogue, the pace of technological change far outstrips the pace of institutional innovation, and this "governance deficit" may lead to a high concentration and abuse of technological power.^[4]

II. Why Multilateral Institutions Are Failing: Institutional Dilemmas from the WHO to the WTO

If the four crises constitute the macro backdrop of fragmentation, then the institutional dilemmas inherent in multilateral organizations themselves are the micro-level accelerating factors. Through my experience leading cross-national policy research for the World Bank and UN-related agencies, I have had a close-up view of how these institutions operate and have witnessed their structural limitations firsthand.

The first dilemma facing multilateral institutions is an extreme version of the "principal-agent problem." In my dialogue with Professor Aumann on incentive design, we discussed in depth the core challenge of institutional design: how to ensure that agents (the bureaucracies of multilateral institutions) faithfully execute the will of principals (member states)? The problem is that multilateral institutions have not one principal but nearly two hundred sovereign states, whose interests are often mutually conflicting. The WHO's predicament is the most typical illustration: its funding primarily depends on voluntary contributions from a few major powers (rather than proportionally assessed dues), which inherently constrains the WHO's independence — major donor countries can steer the WHO's agenda-setting through "earmarked contributions," diverting the institution's attention from the systemic needs of global public health toward specific diseases or specific regions favored by donors. Professor Gostin described this as the phenomenon of the WHO being subject to "donor capture" — an institution that should serve all of humanity is, in practice, serving the priorities of a handful of funders.^[5]

The second dilemma is the trap of the "lowest common standard." Because decision-making in multilateral institutions typically requires broad consensus (if not unanimity), any rule-setting tends to accommodate the member least willing to cooperate — the result being that international rules often remain at the lowest common standard, far below the rigor needed to address the problem. The WTO's Doha Round of negotiations dragged on for over twenty years without reaching completion, precisely because the fundamental disagreements between developed and developing countries on agricultural subsidies and intellectual property rights were irreconcilable. When multilateral negotiations fail to produce meaningful outcomes, countries turn to bilateral or regional agreements — CPTPP, RCEP, the US-EU Trade and Technology Council — further undermining the centrality of the multilateral system.

The third dilemma is the absence of enforcement mechanisms. A fundamental feature of international law is the lack of compulsory enforcement power — there is no "world police" that can force countries to comply with international obligations. This problem exists in every domain of global governance but is particularly acute in the fields of health and climate. The International Health Regulations (IHR) require countries to promptly report public health emergencies, but when a country delays reporting for political reasons, the WHO has neither investigative authority nor sanctioning power. The Paris Climate Agreement sets global temperature control targets, but each country's Nationally Determined Contributions (NDCs) are entirely voluntary, and the withdrawal mechanism is straightforward. As Professor Wilson emphasized in our discussion of mechanism design: the effectiveness of any institution depends on whether it can create sufficient incentives for participants to cooperate, and the current international governance mechanisms are weakest precisely in incentive design — the benefits of rule compliance are shared by all, but the costs of rule violation are externalized by individual countries.^[6]

These three dilemmas together constitute a vicious cycle: multilateral institutions lack legitimacy due to insufficient representation, cannot obtain adequate mandates due to insufficient legitimacy, cannot execute effectively due to insufficient mandates, and further lose legitimacy due to ineffective execution. Breaking this cycle requires not incremental patching of existing institutions but a fundamental rethinking of the global governance architecture.

III. The Deep Connection Between Inequality, Capital, and Governance

Another key dimension of the fragmentation of global governance is often underestimated in mainstream international relations discourse — the erosive effect of global inequality and capital flows on the governance system. My dialogues with Professor Milanovic and Professor Pistor provided indispensable analytical frameworks for understanding this dimension.

In our dialogue, Professor Milanovic articulated his core argument: contemporary globalization has simultaneously narrowed inequality between countries (particularly through the rise of China and India) while exacerbating inequality within many countries. This "dual movement" has far-reaching implications for global governance. At the international level, the economic rise of emerging powers has endowed them with the strength and willingness to challenge the existing order, while growing inequality within Western countries has given rise to populism and economic nationalism — from Brexit to America's "America First" policy, these political forces fundamentally shake the domestic political foundation of multilateralism. When voters perceive that the benefits of globalization have been monopolized by the elite while the costs are borne by the working class, political willingness to support international cooperation recedes.^[7]

Professor Pistor's analysis reveals another layer: the global governance system not only faces external pressures — its internal operations are themselves one of the mechanisms producing inequality. The international investment arbitration system allows multinational corporations to bypass a country's judicial system and directly challenge that country's public policies (such as environmental regulations or labor protections), effectively granting capital holders legal power that overrides democratic decision-making. International intellectual property rules (such as the TRIPS Agreement), under the banner of protecting innovation, consolidate the monopoly position of technologically advanced nations — during the COVID-19 pandemic, the prolonged blocking of developing countries' requests for temporary patent waivers on vaccines was a microcosm of this structural contradiction.

When the global governance system is perceived as a driver of inequality rather than its corrector, it loses its most important asset: the trust of the governed. In my research for the World Bank, a recurring theme was the deep skepticism of developing countries toward "Washington Consensus"-style governance advice — recommendations that often demanded market liberalization and institutional reform while ignoring the different development stages and social contexts of each country. Professor Milanovic pointed out that China's economic success occurred precisely under the condition of refusing to fully accept the "Washington Consensus," posing a fundamental challenge to the policy orthodoxy of multilateral institutions.

These analyses point to a deep conclusion: the fragmentation of global governance is not merely a surface manifestation of great power geopolitical competition but a reflection, at the institutional level, of the internal contradictions of global capitalism. When the governance system cannot reconcile the tensions between efficiency and equity, openness and protection, global integration and domestic legitimacy, fragmentation becomes an inevitable institutional response.^[8]

IV. Technology as Catalyst: New Governance Challenges in the Age of AI and Quantum Computing

If the analysis above depicts the "known causes" of global governance fragmentation, then emerging technologies are creating "unknown variables" — a set of new forces that may fundamentally change the nature of governance challenges.

In my current work leading Meta Intelligence in AI and quantum computing strategy, I witness daily the chasm between technological development and governance frameworks. The cross-border nature of artificial intelligence means that an AI model developed by an American company can be deployed globally in real time, affecting billions of people's access to information, credit assessment, and employment opportunities — yet no international mechanism currently exists to provide coordinated regulation of such cross-border impacts. The EU has enacted the AI Act, and China has issued the Interim Measures for the Management of Generative Artificial Intelligence Services, but these are unilateral domestic regulations that not only lack coordination with each other but, on some key issues, are in fundamental conflict.

The governance challenges of quantum computing are even more severe. Once fault-tolerant quantum computers achieve a breakthrough, the current public-key encryption system — the foundation of the global digital economy and national security communications — will face the risk of being cracked. This is not a hypothetical future scenario but a real threat that intelligence agencies around the world are currently preparing for. However, the transition to quantum security requires global coordination — if some countries complete the upgrade to post-quantum cryptography while others fail to keep pace, severe security vulnerabilities will emerge in global digital infrastructure. Currently, this issue is almost entirely absent from the multilateral governance agenda.

The deeper issue lies in the challenge that technology poses to the governance paradigm itself. Traditional international governance is built on the concept of "territorial sovereignty" — each country possesses exclusive governing power within its territorial boundaries. But the digital space does not recognize borders: data flows across borders, algorithms deploy in real time, and cyberattacks have no nationality. Professor Guillen noted in our dialogue that by 2030, more than half of global economic activity will occur in the digital space — yet the rules we use to govern this space still rest on the assumption of "physical boundaries."^[9]

From Professor Aumann's game theory perspective, technology governance faces a classic "coordination game": all countries would benefit from coordinated global rules, but each country tends to let others act first while it free-rides or preserves maximum policy flexibility. In the absence of an effective coordination mechanism and a credible commitment device, countries will continue to move toward "regulatory fragmentation" — responding to the same set of global technological challenges with different standards, different rules, and different levels of enforcement, each going its own way.

Professor David Christian's big history perspective provides an important warning in this regard. In our dialogue, he emphasized that every major technological leap in human history — from the Agricultural Revolution to the Industrial Revolution — required corresponding innovations in social organization and governance to translate technological potential into lasting civilizational progress. If we are in the midst of a new technological leap driven by AI and quantum computing yet fail to develop matching governance frameworks, the lessons of history tell us that the result may not be progress but turmoil.^[10]

V. Rebuilding Governance: Institutional Innovation Pathways for the Multipolar Era

Facing the reality of fragmentation, we can neither naively expect a return to the American-led unipolar order nor passively accept the end of multilateralism. Drawing on insights from my dialogues with eight scholars, as well as my research and practical experience at the University of Cambridge, the World Bank, and UN-related agencies, I propose five directions for rebuilding global governance in the multipolar era.

First, shift from "universal uniformity" to "variable geometry." A governance model that pursues consensus among all countries on all issues is no longer viable in the multipolar era. A more pragmatic direction is "variable geometry" — forming different cooperative coalitions on different issues. On climate issues, major emitters can form small action coalitions; on AI governance, technologically leading nations can first develop a standards framework and then gradually expand it; on global health, key vaccine-producing countries can establish rapid response mechanisms. This flexible cooperative architecture is not an abandonment of multilateralism but a pragmatic strategy for maintaining international cooperation under a new power configuration. Professor Nalebuff's core insight on negotiation is highly applicable here: effective cooperation does not require all participants to have perfectly aligned interests; rather, it requires finding common interest points between each pair of participants and using these as a foundation to gradually expand the scope of cooperation.^[11]

Second, strengthen the independence and enforcement capacity of multilateral institutions. Taking the WHO as an example, the reform proposal put forward by Professor Gostin deserves serious consideration: shifting the WHO's funding model from reliance on voluntary contributions to mandatory assessed dues, granting the WHO independent pandemic investigation authority (similar to the IAEA's verification model), and establishing sanctioning mechanisms for non-compliant states. The same logic can be extended to other domains — international governance institutions need to move away from being "member state service organizations" and transform into "global public goods providers" with independent mandates and enforcement capabilities. This requires sovereign states to cede some authority — politically difficult, but the lessons of COVID-19 have demonstrated that the cost of sovereignty-above-all can be a global catastrophe.

Third, genuinely incorporate emerging powers into the governance core. For the global governance system to regain legitimacy, it must reflect current power realities rather than those of eighty years ago. This means that Security Council reform cannot be postponed indefinitely, voting rights in international financial institutions must be substantively adjusted, and the formulation of global trade rules must be more inclusive of the interests and voices of developing countries. Professor Milanovic's analysis reminds us: if the existing system does not proactively open space for emerging forces, they will build alternative arrangements outside the system — at that point, fragmentation will no longer be a "loss of governance efficiency" but a "confrontation of parallel orders."

Fourth, establish new multilateral platforms for technology governance. Emerging technologies such as AI, quantum computing, and synthetic biology require dedicated international governance mechanisms — but this does not mean establishing new United Nations agencies. A more effective model may be "multi-stakeholder" platforms — governance mechanisms involving joint participation by governments, businesses, academia, and civil society, combining the political legitimacy of inter-state negotiations with the professional expertise of technical communities. My work experience at the Cambridge Centre for Alternative Finance (CCAF) gave me a deep appreciation of how some successful cases in fintech regulation — such as the Global Financial Innovation Network (GFIN) — are practical applications of this multi-stakeholder model.

Fifth, rebuild the narrative foundation of global governance. Institutional reform requires political will, and political will requires the support of public narrative. Professor Christian's big history framework provides a powerful narrative resource here: from the Big Bang to every major leap in human civilization, progress has been achieved through cooperation at ever-larger scales — from tribes to city-states, from nation-states to international organizations. In an era where nuclear weapons, AI, and climate change jointly define the risk landscape, global cooperation is not idealism but the rational choice for species survival. This narrative needs to move from the academic sphere to the public domain and become the cultural foundation supporting the political will for multilateralism.

In retrospect, the fragmentation of global governance is one of the most significant institutional challenges of our time. It will not be resolved through a single reform proposal or the joint declaration of a summit — it requires sustained institutional innovation, difficult power adjustments, and reimagining how humans organize collective life in a multipolar and technology-driven world. During my years leading research for the World Bank and the United Nations, I witnessed the fragility of the multilateral system; in my dialogues with eight scholars, I saw the intellectual resources for rebuilding. Fragmentation is a reality, but it is not destiny — provided we have sufficient wisdom and courage to design a governance architecture suited to this new era.^[12]
