On 20 September 2026, Brazilian President Luiz Inácio Lula da Silva, European Council President António Costa, Kenyan President William Ruto and Canadian Prime Minister Mark Carney argued that growing geopolitical fragmentation is making, rather than reducing, the need for multilateral cooperation. In a joint Financial Times op-ed, they presented “Partners for Multilateralism” (P4M), an open framework bringing together countries across regions to push for reform of the UN and other multilateral institutions. Their argument is less about preserving the post-1945 system unchanged than about adapting it to current challenges, including conflict, economic coercion, AI, climate change, health security and disruptions to global supply chains.
