Relationship assessment
Practical cooperation between Slovakia and Ukraine has continued alongside disputes over military aid and gas transit.
Slovakia toward Ukraine
+15Slovakia has provided humanitarian assistance and support for Ukrainian refugees, and earlier Slovak governments transferred military equipment to Ukraine. The Fico government later ended further government military donations, while commercial arms sales remained possible. Slovakia has also had disputes with Ukraine over the end of Russian gas transit.
Ukraine toward Slovakia
+10Ukraine has participated in practical bilateral cooperation with Slovakia, while ending Russian gas transit through its territory in 2025, a decision that affected Slovak energy interests and prompted a dispute. The scope of Ukraine’s other direct government cooperation with Slovakia is unclear.
Overall relationship
+15The relationship has a durable basis in neighboring-state cooperation and Slovakia’s support for Ukraine during the Russian invasion, including humanitarian and refugee assistance and earlier military transfers. That cooperation is tempered by changes in Slovak policy on military aid and by disputes over gas transit. The relationship is neither a close, consistent partnership nor predominantly adversarial.
