Throughout 2025, Ukrainian foreign policy experienced one of the most complex and multifaceted periods in its modern history. President Volodymyr Zelenskyy stated that during this year Ukraine did not cede a single international platform to Russia on issues critical to its own security and international standing. This formulation reflects not only diplomatic tactics but also a deep strategic reorientation of Kyiv toward strengthening its global influence while simultaneously pursuing the diplomatic isolation of Moscow.

Formally, this statement was made on the occasion of the professional holiday of the diplomatic service, yet it points to a far broader trend: from the first days of the full-scale invasion, Russian diplomacy came under pressure from sanctions, suffered reputational losses in a number of key institutions, and faced sustained criticism from Western allies. Ukrainian diplomats, in turn, worked not only to consolidate their own positions within the UN, the EU, and other international organizations, but also to actively block Moscow’s attempts to restore its former influence or regain the status of an equal partner on the international stage. This effort included preventing Russia’s participation in elections to governing bodies of international institutions and coordinating with key Western allies to deny it a return to de jure legitimacy as a global actor, especially in forums addressing accountability for aggression and adherence to international law.

What makes Ukrainian diplomatic activity particularly significant is not only the struggle over formal mandates and seats, but also the entrenchment of an ideological and moral argument against the war. From calls to uphold sovereignty to active lobbying for expanded sanctions pressure, Ukraine has become a catalyst for international debates on the principle that an aggressor cannot act as a partner in matters touching the fundamental foundations of the international order. This has been especially evident against the backdrop of efforts by some Western capitals, with varying degrees of success, to balance support for Kyiv with a desire to maintain dialogue with Moscow on critical geopolitical issues.

At the same time, Ukrainian diplomacy is not confined to denying Russia a role as a subject of international negotiations. It actively engages allies in developing peace concepts, contrasting Moscow’s proposals with the vision of a just and sustainable settlement. In 2025, amid ongoing peace initiatives and negotiations involving the United States and the European Union, Ukraine has advocated for a comprehensive peace plan with genuine security guarantees, rather than a temporary ceasefire or arrangements that would allow Russia to continue its aggression under a different pretext.

Such diplomacy represents not only strategy but tangible influence over processes in which Ukraine’s position shapes the outcome of global decisions. This is reflected in the growing support for Ukrainian interests in working groups, policy documents, and resolutions, while Russia is increasingly perceived as a source of destabilization rather than an equal partner in international dialogue. Fundamentally, this approach signals Ukraine’s transition from a state fighting for its very survival to an active participant in the international order – one that helps shape the rules and norms intended to prevent the recurrence of aggression on such a scale.

It is clear that this diplomatic course also entails a number of challenges. The strategic isolation of Russia on the world stage provokes a sharp reaction from its political establishment and places complex demands on Ukraine to maintain unity among its allies, where views on the tactics of pressure may differ. Nevertheless, at least at this stage, Ukraine’s diplomatic service demonstrates the capacity not only to withstand external challenges but also to set an active agenda, strengthening its influence on international processes and laying the groundwork for a future peace agreement that takes into account Ukraine’s independence and territorial integrity.
