Excerpt | Henry Huiyao Wang on Reforming the UN Security Council

In this excerpt from his new open-access Springer book, China and the Next Global Order, CCG President Henry Huiyao Wang proposes expanding the Security Council and curbing the unilateral veto.

We are pleased to share an excerpt from China and the Next Global Order: Coming Multipolar World and Great-Power Coopetition, the new book by Henry Huiyao Wang, Founder and President of the Center for China and Globalization (CCG). Published by Springer Nature in 2026 as part of the “China and Globalization” series, the book is available as an open-access publication.

The volume brings together Wang’s writings on China’s evolving role in globalisation, global governance, great-power relations, and the emerging multipolar world. The following excerpt, first published by Foreign Policy on September 30, 2025 and included in this collection, argues that the UN Security Council must become more representative and less vulnerable to paralysis. It proposes expanding the body around the G21 and allowing a supermajority of the Council and General Assembly to override a unilateral veto.

How to Fix the Security Council

Adding Members and Removing the Unilateral Veto Would Make the Body Stronger.

At the 80th United Nations General Assembly high-level debates last week, a host of global leaders called for a more effective and representative Security Council. In the words of Finnish President Alexander Stubb: “If countries from the Global South, from Latin America, from Africa, from Asia, do not get agency in the system, they will turn their backs against the United Nations.”

Indeed, the Council’s shortcomings are playing out all too clearly today in Gaza and Ukraine. The United States has used its unilateral veto to block a host of resolutions calling for a ceasefire in Gaza, enabling the genocidal conflict to continue. Meanwhile, Russia has consistently blocked any meaningful Security Council response to the war in Ukraine since 2022, despite international condemnation and profound humanitarian suffering.

However, despite the Security Council’s flaws, there is no real substitute for it. If it drifts into irrelevance, this would simply remove the last vestiges of effective global coordination. The challenge, then, is not whether to reform the council, but how to do so.

It is against this backdrop that Chinese President Xi Jinping launched a new Global Governance Initiative. Xi is calling for a fairer and more inclusive multilateral system, one without double standards that places the United Nations at its core.

To realize this global vision, the Security Council should enact structural and procedural reform. First, the council should expand its membership to better reflect the world of today. Second, it should develop a mechanism to limit the use of unilateral vetoes to prevent a single state from standing athwart an international consensus. Together, these reforms can revitalize the Security Council’s credibility and capacity, transforming it from a forum of gridlock into a more responsive and effective guardian of the peace.

The Security Council’s current structure—five permanent members and 10 rotating nonpermanent members—reflects, at best, the geopolitical realities at the time of the last set of Security Council reforms in 1965. This structure should be updated by adding a new class of associate permanent member seats.

To that end, all current G21 (formerly G20) members should be given a seat on an expanded Security Council. This would eliminate the 10 existing rotating seats and create 16 new permanent associate seats. These new states would not have an individual veto, but together with the other four permanent members, they could override the use of the unilateral veto.

This would preserve the institutional legacy of the original five full members, while elevating voices that reflect today’s multipolar economic and political order. In doing so, it would enhance the council’s legitimacy, improve regional representation, and embed the Security Council more firmly within the real architecture of the current global order.

Previous reform efforts have stumbled over the question of how to allot new seats in the Council. Here, the G21 offers an elegant solution. It is comprised of an even mix of developed and developing countries. Using it as the basis for reform addresses some of the underrepresentation of the Global South while still recognizing the enduring power of incumbents. Today, the G21’s members comprise over 85% of global GDP, and has already helped coordinate multilateral responses to some of the world’s most pressing economic challenges. Under this new model the expanded UN Security Council would consist of Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, South Korea, Mexico, Russia, Saudi Arabia, South Africa, Túrkiye, the United Kingdom, and the United States, along with the African Union and the European Union, which would each have one collective vote.

The second reform necessary to restore function is a procedural one. The unilateral veto has created paralysis in the Security Council, allowing even urgent humanitarian measures to be stalled indefinitely. To this day, the veto has seen use a staggering total of 324 times in less than 80 years at an average rate of four vetoes a year. This includes 159 vetoes by the Soviet Union or Russian Federation, 94 by the United States, 32 by the United Kingdom, 21 by China, and 18 by France.

Even seemingly straightforward matters, such as the admission of new members, can become mired in contention as the Soviet Union adroitly demonstrated early in the Cold War and as the United States demonstrates today in blocking Palestinian membership. Beyond this, the impact of the veto is likely worse than we can see. Its looming presence ensures that many resolutions are killed behind closed doors in private conversation, as those drafting the documents are quietly informed that their resolutions will be vetoed.

Previous reform initiatives have attempted to tackle the veto problem. The French–Mexican proposal, first advanced in 2013, called for permanent members to voluntarily suspend their veto in cases of mass atrocities. The Accountability, Coherence, and Transparency Group later advanced a code of conduct, now supported by more than 120 states, which urges P5 states to retain from using their vetoes in situations of genocide, crimes against humanity, or war crimes.

But a more substantial fix is required. To solve the problems created by the unilateral veto, we must weaken it by instituting a supermajority override. Under this proposal, if over two-thirds of the expanded Security Council, that is to say 15 of its members, and two-thirds of the General Assembly voted to override the veto of a single P5 member, the resolution in question would pass.

After all, if two-thirds of both bodies can agree to override a single P5 member veto, it clearly represents a broad international consensus. A singular P5 member should not be able to block a UNSC resolution passed by all other permanent members, two-thirds of the other 16 permanent associate members, and two-thirds of the 193 members in the General Assembly.

This new proposal would benefit countries in the Global South that previously were unable to meaningfully take part in international rulemaking and security due to inviolable vetoes from above. At the same time, there is no reason for existing P5 members to fear the consequences of this reform. The P5 would still be able to impose a binding veto on any resolution so long as at least two members were in agreement. This would offer some reassurance, even as it prevents a single power from derailing collective action and raised the political cost of casting a veto in the first place.

This simple change would have immediate ramifications. From Yemen to Gaza, it would open the door to resolving conflicts that have gone from ugly to horrific. The removal of the unilateral veto would break down the barrier that has all too often kept UN peacekeepers and relief efforts from addressing some of the worst tragedies in history.

Reforming the UN would signal a renewed commitment to the founding ideals of the United Nations—peace, cooperation, justice, human rights, and shared responsibility. The result would be a Security Council better suited for the present and better prepared for the future.
