What the September 2025 diplomatic shifts signalled

Summary

A look back at two developments reported in the days before 29 September 2025: Ukraine's restored ties with Syria and Lithuania's wider rules on shooting down drones.

What did the days leading up to 29 September 2025 show about Ukraine's diplomatic and security position in the region? Two developments reported shortly before that date offer a partial answer.

A diplomatic reset with Damascus

On 24 September 2025, Ukraine and Syria restored diplomatic relations. Presidents Ahmed al-Sharaa and Volodymyr Zelenskyy met on the sidelines of the eightieth session of the United Nations General Assembly. Ukraine had broken ties with Syria in 2022, after the government of Bashar al-Assad recognised the Russian-occupied territories in Donetsk and Luhansk. As reported at the time, the Ukrainian side described that recognition as the reason for the rupture, and the restoration followed in a new political setting in Damascus.

Lithuania widens its rules on drones

A day earlier, on 23 September 2025, Lithuania's parliament authorised its military to shoot down any unauthorised drones in its airspace. The move followed recent incursions by Russian drones into the country. Previously, only drones judged to be armed, or to pose an imminent threat to critical state assets, could be targeted.

The change sits within a wider pattern of airspace violations since Russia's full-scale invasion of Ukraine on 24 February 2022. States near the conflict, particularly NATO members that Russia has labelled unfriendly, have reported numerous incursions. Most were attributed to Russian equipment such as drones and aircraft, though Ukrainian equipment was responsible on several occasions, most notably in the 2022 Przewodów explosion, which killed two Polish civilians.

Two tracks, one backdrop

The two stories concern different places and instruments: one is an exchange of diplomatic recognition at the UN, the other a legal change in a neighbouring NATO state. Both show countries adjusting their formal positions in response to the war and its consequences. Syria and Ukraine reversed a break rooted in the 2022 recognition of occupied territories, while Lithuania lowered the threshold for acting against drones after Russian ones entered its airspace.
