A New Era of International Cooperation: Why Countries Are Building Smaller Coalitions

For decades, international cooperation was often associated with large institutions, global agreements and diplomatic frameworks designed to bring as many countries as possible around the same table. The principle was straightforward: problems that crossed borders required common rules and collective solutions.

That model is under growing pressure.

Geopolitical competition has intensified, trust between governments has weakened and disagreements over trade, security and technology have become harder to resolve through traditional multilateral channels. Yet cooperation itself has not disappeared. Instead, it is increasingly taking different forms, with countries turning to smaller, regional and issue-specific partnerships.

The change matters because it suggests that the future of international cooperation may not be defined by the decline of collaboration, but by its transformation.

The Old Model Is Becoming Harder to Maintain

Large international agreements have always been difficult to negotiate. The more countries involved, the more interests have to be reconciled.

That challenge has become more pronounced as governments place greater emphasis on national security, economic resilience and strategic independence. The World Economic Forum’s 2026 Global Risks Report describes a global environment in which multilateral institutions are under pressure from declining trust, protectionism and geopolitical competition.

The result is not necessarily the end of international rules. It is a growing preference for arrangements that can produce practical results without requiring universal agreement.

Cooperation Is Becoming More Targeted

The Global Cooperation Barometer 2026 offers an important distinction. Overall global cooperation remained broadly stable, but the structure of that cooperation changed. Traditional multilateral approaches weakened in several areas, while smaller and more flexible forms of cooperation continued to expand.

This can be seen in areas such as trade in services, data flows, investment and technology.

Instead of trying to create one comprehensive agreement covering every country and every issue, governments can cooperate where their interests overlap. A smaller group may agree on a particular technology standard, coordinate infrastructure investment or work together on an environmental project without resolving every broader political disagreement.

It is a less ambitious model, but it can also be more achievable.

Regional Partnerships Are Gaining Importance

Regional organisations have an increasingly important role in this changing environment.

Countries that share borders, trade routes, energy networks or environmental challenges often have strong practical reasons to cooperate even when their wider geopolitical interests differ.

The Global Cooperation Barometer found that regional and smaller coalitions have become particularly important in areas where global cooperation is under strain. In peace and security, for example, regional organisations have taken on responsibilities that larger multilateral mechanisms have struggled to manage.

Regional cooperation can also be faster. Governments are dealing with a smaller number of participants and problems that are more directly connected to their immediate interests.

That does not make regional arrangements a substitute for global institutions. It gives countries another level at which cooperation can function.

Trade Is Being Reorganised Around Trust

Economic relationships are also changing.

For many years, global trade was heavily influenced by the search for efficiency. Companies built international supply chains around cost, production capacity and access to markets.

Geopolitical tensions have introduced another consideration: trust.

Governments and businesses increasingly want to know whether critical suppliers will remain dependable during a political crisis. This is contributing to a shift toward trading relationships that are considered strategically safer or more predictable.

The World Economic Forum’s 2026 cooperation research found that goods trade continued to grow, although more slowly than the global economy, while trade flows increasingly shifted toward more aligned partners.

This does not mean that globalisation is ending. It means that economic interdependence is being managed more deliberately.

Technology Needs New Forms of Cooperation

Technology creates an especially complicated case because countries can simultaneously compete and cooperate.

Governments want advantages in artificial intelligence, semiconductors, quantum technologies and advanced computing. At the same time, these technologies cross borders and depend on international research, investment, standards and supply chains.

The result is a new form of technological diplomacy.

Countries may compete over strategic technologies while still cooperating on technical standards, scientific research or safety questions. Companies and universities also operate across national boundaries, making complete technological separation difficult.

This creates pressure for new international frameworks that can manage competition without preventing useful collaboration.

Climate Cooperation Is Taking a Different Route

Climate policy provides another example of how international cooperation is changing.

Global climate negotiations remain important, but practical progress is increasingly being supported by regional groups, industry partnerships and coalitions focused on specific technologies or sectors.

The 2026 Global Cooperation Barometer found that cooperation on climate and natural capital increased, although it remained below the level required to meet global goals. It also highlighted the growing role of regional groups that are combining decarbonisation with energy-security priorities.

That combination is significant.

Governments are more likely to support climate measures when they also address domestic economic and security concerns. Clean energy is therefore increasingly being discussed not only as an environmental issue, but as part of industrial strategy, energy independence and long-term competitiveness.

Security Cooperation Is Under the Greatest Pressure

The area where international cooperation faces perhaps its most difficult test is peace and security.

The Global Cooperation Barometer found that cooperation in this field has declined substantially, with almost every tracked measure in 2024 below pre-pandemic levels. Conflicts have intensified, military spending has increased and global mechanisms have struggled to prevent or resolve crises.

Yet even here, smaller forms of cooperation have shown some resilience.

Regional organisations and limited diplomatic coalitions can sometimes create channels for de-escalation when broader negotiations are blocked. The report points to regional peacekeeping efforts and minilateral diplomacy as examples of this more fragmented approach.

This may become increasingly important in a world where major powers are less willing to compromise through universal institutions.

The Problem of Trust

Behind many of these changes lies a more fundamental problem: trust.

International agreements work because governments believe that other participants will respect commitments. When that confidence weakens, even technically useful arrangements become harder to maintain.

A 2026 report from the Stimson Center and the Doha Forum similarly identifies declining trust as a major obstacle to international cooperation, arguing that distrust affects diplomacy, economic relations, technology and security.

Rebuilding trust is therefore not simply a diplomatic exercise. It requires institutions to demonstrate that cooperation produces tangible benefits and that rules are applied with a reasonable degree of consistency.

Small agreements can sometimes help because they allow governments to build confidence through practical results.

A More Flexible International System

The emerging system may therefore look less like one large international architecture and more like a network of overlapping arrangements.

A country might participate in a regional energy partnership, a technology coalition, a trade agreement and a security dialogue at the same time. The participants may differ in each case, depending on the problem being addressed.

This creates complexity, but it also provides flexibility.

If cooperation becomes impossible in one forum, governments may still find another route. If a global agreement stalls, a smaller group can continue working on a specific part of the problem.

The danger is fragmentation. Too many separate arrangements can create conflicting standards, duplicated institutions and unequal access to international cooperation.

The challenge will be finding a balance between flexibility and coherence.

What Comes After Multilateralism?

It may be too early to say that the traditional multilateral system is being replaced. Global institutions remain essential for issues that cannot realistically be managed through small coalitions alone.

Financial stability, climate change, global health, international trade and cross-border security threats all require some degree of broad coordination.

But the way countries reach that coordination may change.

The World Economic Forum’s 2026 research suggests that the future of cooperation will increasingly depend on choosing the right format for the right problem: global mechanisms where universal coordination is necessary, and smaller or regional coalitions where targeted action can produce faster results.

That is a more pragmatic approach than the assumption that every international problem requires the same diplomatic structure.

Cooperation After the Age of Certainty

The international system is entering a period in which cooperation can no longer be taken for granted. Geopolitical rivalry, economic competition and declining trust are making broad agreements harder to achieve.

But the evidence does not point to a world in which countries simply stop working together.

Instead, cooperation is becoming more selective, practical and flexible. Governments are forming smaller partnerships, strengthening regional relationships and working together where interests clearly overlap.

That may produce a less orderly international system than the one imagined by earlier generations of globalisation. It may also prove more adaptable to a world in which countries disagree about many things but still need one another to solve problems that cross every border.

The future of international cooperation may therefore be smaller in scale, but not necessarily smaller in importance. Its success will depend on whether these new networks can preserve enough trust and coordination to prevent a fragmented world from becoming a disconnected one.
