Pedro Sánchez opened Spain's participation in the United Nations High-Level Week by challenging the push for smaller international blocs. Speaking in New York at the Partners for Multilateralism (P4M) event on 21 September 2026, he said a fragmented world cannot be answered with more fragmentation. He argued that peace depends on widening trust.
The speech put the future of the rules-based order at the centre of Spain's position. Sánchez defended universal, inclusive multilateralism as countries increasingly form coalitions of like-minded states and seek answers in smaller circles. His official agenda on 21 September 2026 included participation in the Partners for Multilateralism summit at UN headquarters and a separate meeting with UN Secretary-General António Guterres.
That is the approach the Spanish prime minister rejected. Limited coalitions, he argued, should leave room for international cooperation. The choice presented in New York was between institutions that widen participation and arrangements that leave urgent problems to a smaller group of countries.
The European Union organised the P4M event alongside Canada and Kenya. It opened Sánchez's programme during United Nations High-Level Week and gave Spain a platform to explain its view of the international system. The European Council called the summit a new coalition initiative ahead of the 81st session of the UN General Assembly. It was framed as more than a one-off political appearance. The European Council said the P4M initiative aims to reform the UN and global governance, while improving coordination on artificial intelligence and climate, as well as health. It seeks to make international institutions more representative and legitimate, and to improve their effectiveness.
His position rests on several commitments. Spain opposes wars and supports diplomacy. It backs sustainable development while seeking a fairer international financial architecture. Sánchez also defended multilateral institutions that are more inclusive and legitimate. They should give a voice to people and countries long pushed to the margins.
Inclusion is basic to this argument. Spain says international legitimacy should be built through institutions that widen representation, rather than through tighter circles of trust. The same approach links peace with diplomacy and development with a fairer financial system.
Spain's agenda in New York also goes beyond the P4M message. The Spanish foreign-policy programme, citing the Ministry of Foreign Affairs, puts international law and the wars in Ukraine and the Middle East on the agenda, alongside reform of the UN system through the UN80 process. Sánchez's call for broader cooperation is part of a wider debate about how international rules and institutions should work.
No new measures or agreements were announced. The Spanish government set out a clear political position at the start of its UN engagement: pressure on the rules-based order should be met with wider cooperation, not its dismantling. The initiative has also drawn support from a wider political circle. Brazil has appeared in international reporting and in a joint Financial Times opinion article linked to the project.
Sánchez's intervention gives Spain a clear line at the international forum. Its multilateral agenda links opposition to war with diplomacy, and sustainable development with institutional inclusion. Spain is defending multilateralism as a system that must remain universal and legitimate, with a voice for those long excluded. As the debate turns toward fragmentation, the position presented in New York calls for a wider circle.
