How does NATO engage with non-member states through partnerships?

NATO promotes stability through partnerships with non-member countries. These foster dialogue, cooperation, and practical collaboration on security issues, without Article 5 guarantees. Initiatives include the Euro-Atlantic Partnership Council (EAPC) for political consultations. The Partnership for Peace (PfP) program allows tailored cooperation plans. Regional dialogues like the Mediterranean Dialogue and Istanbul Cooperation Initiative, alongside global partners, enhance international security cooperation.

  • Euro-Atlantic Partnership Council (EAPC): Dialogue.
