Multilateralism is the lynchpin of the UN’s work. It’s what makes tackling humanity’s greatest challenges possible.
So what does this term — often derided for being wonky and clunky — mean exactly?
Simply put, multilateralism is the technical word to describe a universal truth: We are stronger together.
It is perhaps best understood by its impact. Some of humanity’s greatest wins have been the result of coordinated and collective action that transcends borders and geopolitical hurdles. Thanks to multilateralism, the world has eradicated smallpox, helped close the ozone hole, and lifted 1 billion people out of extreme poverty.
Yet today’s global challenges are testing the international system in unpredictable ways. From climate change to artificial intelligence, the world is facing urgent, existential issues that cannot be tackled by any one nation alone. To meet the moment, we need fresh, bold solutions to strengthen global solidarity at a time of growing polarization, inequity, and distrust. Multilateral systems — both including and beyond the United Nations — need to be reimagined and revitalized to address 21st century challenges through collective, intergenerational action. Leaders must seize this moment to strengthen the UN so it can and continue to deliver inclusive, equitable progress now, and for future generations.
In other words, multilateralism needs an upgrade. As calls for a more inclusive, networked, and equitable international system surge, the UN Foundation is bringing together the work and voices of the foremost thinkers, planners, and doers to spark global dialogue, and create lasting change.
It is time for humanity to rise and redefine what is possible — together.
