Key topics included the Migration and Asylum Pact, migration management, and Bulgaria’s integration into Schengen, with a focus on the importance of secure external borders.

Borissov praised the collaboration with Frontex and highlighted operational cooperation with Romania and Greece, as well as coordination with Turkey to address illegal migration.

The European Commission’s 2025 State of Schengen Report indicates that Bulgaria and Romania's accession has positively impacted the EU economy by eliminating internal border delays worth billions of euros annually.

Borissov highlighted that Bulgarian citizens are already experiencing the benefits of being part of Schengen, which facilitates easier travel and reduces bureaucracy for over 450 million Europeans.

The discussion also covered broader security issues, including the impacts of Russia's war in Ukraine and conflicts in the Middle East, which necessitate close cooperation among EU member states.

On June 30, 2025, Boyko Borissov, leader of the GERB party, met with European Commissioner for Home Affairs and Migration Magnus Brunner in Sofia to discuss the protection of the Schengen Area’s external borders.

During the meeting, Borissov emphasized Bulgaria's critical role in safeguarding the Schengen borders, asserting that the country not only protects itself but also the entire European Union.

He reiterated that Bulgaria is not merely a participant in Schengen but a guardian of its principles and integrity, highlighting its strategic importance in European border security.

He noted a decline in migration pressure along the Bulgarian-Turkish border since September 2023, emphasizing the shared responsibility of all EU members in strengthening border security.

Zhelyazkov reaffirmed Bulgaria's commitment to border security, stating that temporary internal border controls with Romania should not be extended beyond July 1, 2025.

He argued that the removal of internal border controls after Bulgaria’s entry into Schengen has not compromised security, justifying the lifting of temporary controls on the Bulgarian-Romanian border.

Over the past three years, the European Commission has provided more than €300 million for border security enhancements, benefiting both Bulgaria and the EU's security framework.
