This project builds on the momentum of the ASCEND-WB6 initiative (2024–2025), which laid the groundwork for deeper security integration of the Western Balkans Six (WB6) into the European Union’s institutional architecture. This work has already contributed to some important changes. The EU’s Rule of Law Report now includes all candidate countries, and there is growing support among both EU institutions and member states for granting ENISA observer status to the WB6. KCSS also provided input to the European Commission’s consultation on revising the EU Cybersecurity Act, proposing a pathway for structured WB6 participation. The next phase of the project aims to continue this work and avoid the loss of momentum at a time when both political attention and institutional willingness remain within reach to facilitate greater security integration of WB6 in the EU. The first part of the project will maintain engagement around the three original priorities: ENISA participation, FDI screening alignment, and rule of law monitoring. This will include a monitoring report, further consultations, and an online roundtable with relevant EU and regional stakeholders. The second part introduces a broader security integration agenda by focusing on three EU agencies crucial for internal security and justice: the Fundamental Rights Agency (FRA), the European Public Prosecutor’s Office (EPPO), and Eurojust. The project will support efforts to deepen cooperation with these agencies, building on existing examples of engagement in the region. Three policy briefs will be produced to map current levels of collaboration and outline steps for progress, each accompanied by a public event. The project will also assess cooperation between the WB6 and Europol and develop media outreach in the region to communicate the importance of structured engagement with EU agencies. By continuing to link regional priorities with EU-level frameworks, the project seeks to support gradual and practical steps toward deeper integration of the Western Balkans into Europe’s security and rule of law architecture.
