When Cities Take Center Stage in Global Transformation: The Deep Signals of the Brussels 2026 Congress

In 2026, Brussels will host a global conference that may be underestimated — the Cities Alliance Congress. While most people focus on competition between nations and great-power rivalry, this congress attempts to put cities back at the center of global transformation. This signal deserves to be taken seriously, because it may herald a deep shift in the logic of global governance: when action at the national level reaches an impasse, cities are becoming the cutting-edge laboratories for addressing climate, migration, and technological change.

Why Brussels?

The city itself is an overlay of multiple symbols. As the administrative hub of the European Union, it represents postwar Europe's institutional experiment of exchanging shared sovereignty for peace and prosperity. That the Cities Alliance has chosen to convene here may suggest a new kind of multilateralism: no longer merely negotiations between states, but a parallel track built on global city networks. The rise of this "subnational diplomacy" is not new, but at a time when global crises are piling up, its weight is significantly increasing.

The Contradictions and Potential of Cities

Cities have become centers of transformation because they concentrate most of the contradictions humanity faces. More than half of the global population lives in cities, and that proportion is expected to rise in the coming decades. Cities are a major source of carbon emissions and also the front line of climate impacts. Cities are hubs of migration and mobility, and the places where inequality manifests most acutely. Cities have the densest innovation networks, yet they also bear the heavy strain of aging infrastructure and housing pressure. When political cycles and institutional constraints at the national level cause slow action, cities are often able to respond in more pragmatic ways.

Redefining Cooperation and Mobility

This congress places special emphasis on "rethinking cooperation and mobility." That deserves analysis. The redefinition of "cooperation" may point to new forms of synergy across cities, regions, and even sectors. In the past, city cooperation was mostly concentrated on sister-city relationships and cultural exchange. Today, however, policy learning, joint procurement, and mutual recognition of standards among cities have become substantive institutional tools. For example, many cities around the world have formed climate alliances, mutually committing to carbon emission targets that are even more ambitious than national goals. "Mobility" refers not only to population migration, but also to the flow of capital, data, services, and innovation between cities. The acceleration of these flows is reshaping urban competitiveness.

The Dark Side of City-Centrism

But putting cities at the center does not mean avoiding complexity. Cities are not monolithic; they contain enormous conflicts of interest and inequality. The rise of city power may also raise new questions of accountability: do city leaders have enough legitimacy and resources to bear such great responsibility? Could cooperation between cities be swept up in great-power geopolitical rivalry? The Brussels congress may not provide immediate answers to these questions, but it at least offers a framework for discussion.

The Intersection of History and the FutureFrom a longer historical perspective, cities have always been engines of civilizational change. From the Hanseatic League to today's global city networks, connections between cities have often given rise to new economic and cultural forms earlier than national borders. Today, technological revolution has dramatically lowered the cost of collaboration among cities, while global challenges force them to seek new solutions.

Perhaps the most significant meaning of the 2026 Brussels conference is not reaching a specific agreement, but establishing a recognition: the success or failure of global transformation will largely depend on whether cities can gain greater autonomy, more flexible cooperation mechanisms, and more sustainable resource allocation. Cities are transforming from passive executors waiting for national policies into actors that actively shape the future.

Of course, we must remain clear-headed. The high profile of the urban agenda cannot conceal the reality of uneven resource distribution at the national level. Many small cities in developing countries still lack basic capacity and funding. The international community needs to establish inclusive mechanisms to ensure that the elevation of cities' role is not a privilege of a few global cities.

In conclusion, when Brussels becomes the focus of the urban agenda in 2026, what we are seeing is a governance paradigm shift in the making. Cities are no longer just the stage backdrop of globalization; they are stepping onto center stage. The impact of this shift will gradually unfold over the coming decades. All those concerned with global affairs should keep their eyes on these rapidly changing urban nodes.
