While most nations reaffirmed their support for Ukraine, the absence of Bulgarian leadership and the continued non-alignment of Serbia underscore shifting geopolitical priorities in the Balkans.
Regional Alignment and the “Kyiv Summit” Shift
The summit in Kyiv served as a platform for Southeast European leaders to coordinate on security and the ongoing recovery of Ukrainian infrastructure. According to reporting by 24chasa.bg, discussions centered on long-term stability and the path toward European Union integration.
However, the composition of the attendee list revealed notable gaps. Dnevnik.bg noted the absence of Rumen Radev and Iliana Iotova, even as other heads of state from the region were present to engage directly with President Volodymyr Zelenskyy.

Serbia remains the only country in Southeast Europe that has declined to sign the joint declaration issued at the “Southeast Europe – Ukraine” summit, according to the Bulgarian News Agency (BTA).
Diverging Diplomatic Paths in the Balkans
Offnews.bg reports that Moscow has shown little inclination to praise the Bulgarian leadership, noting that even when Sofia slows or halts its support for Kyiv, the Kremlin’s rhetoric remains critical.

Meanwhile, the incident involving a drone strike near the Romanian border has forced a new level of security cooperation. As reported by Eurocom, Romania and Ukraine have initiated high-level talks focused on early warning systems.

The following table outlines the current diplomatic posture of key regional actors based on recent summit attendance and policy declarations:
