1. The European Union welcomes the holding of the first EU–UK Summit in London on 19 May 2025, marking a new chapter in our strategic relationship. The EU was represented at the Summit by European Council President António Costa, European Commission President Ursula von der Leyen, and HR/VP Kaja Kallas. The EU thanks UK Prime Minister Keir Starmer for hosting what proved to be a timely and genuinely productive Summit.

2. The Summit underscored our shared values and mutual commitment to peace, security, and multilateralism at a time of growing geopolitical instability. It resulted in three key outcomes that form the basis for a reenergised strategic partnership:

• A Security and Defence Partnership;

• A Joint Statement on Cooperation on Global Issues; and

• A Common Understanding on a Renewed Agenda for Cooperation.

3. The resulting documents reflect our shared responsibility - to our citizens and to the international community. It is in the mutual interest of both the EU and the UK to strengthen cooperation on security and defence. Together, we are stronger: stronger for peace, for security, and for prosperity in Europe and beyond.

4. At the core of this renewed momentum and ambition is the conclusion of the EU–UK Security and Defence Partnership. This Partnership provides a robust, forward-looking framework for structured dialogue and tangible cooperation. It will boost cooperation through regular high-level dialogues and strategic consultations in areas such as support for Ukraine; security and defence initiatives, including the defence industry; mobility of military materiel and personnel; maritime and space security; peacebuilding and crisis management; climate and security nexus; cyber issues; countering hybrid threats and strengthening the resilience of critical infrastructure; as well as combating foreign information manipulation and interference.

5. The Summit also reaffirmed our shared commitment to effective multilateralism, including continued support for the rules-based international order and institutions such as the United Nations and the OSCE. We welcome the explicit reference to the OSCE in the Joint Statement, which highlights its ongoing relevance in promoting security, cooperation, and respect for fundamental principles, including the Helsinki Final Act and subsequent OSCE commitments. In this context, the EU underscores the OSCE’s role as a platform for advancing our shared objectives in promotin gpeace, stability, and comprehensive security.

6. The renewed commitment by both the EU and the UK to multilateral approaches grounded in international law, including the UN Charter, offers a valuable opportunity to strengthen synergies with our engagement in the OSCE - particularly in addressing urgent security challenges, notably Russia’s ongoing war of aggression against Ukraine and its repercussions for European and global security. We encourage further efforts to ensure accountability for all international crimes and human rights violations and abuses.

7. Looking ahead, the EU underlines the importance of the effective implementation of the Summit outcomes. This Summit marks the first step in our new Strategic Partnership. We remain committed to building on this momentum to advance our shared interests and values and to contributing- together with other international partners - to a more peaceful, secure, and cooperative international environment. We look forward to welcoming our British friends to Brussels next year, as we continue to deepen this renewed cooperation.

Albania, Bosnia and Herzegovina, Georgia,Montenegro, North Macedonia, Republic of Moldova and Ukraine align themselves with this statement.
