Ukraine’s president will co-host a summit with Albania’s government on Wednesday that’s meant to encourage further support for Kyiv by southeastern European countries as signs of fatigue grow two years after Russia’s invasion. It is not immediately clear what the summit is expected to achieve. No agenda was publicly available ahead of the summit, and officials with NATO member Albania gave no details. Not all participating countries are in full support for Ukraine in its war against Russia. Kremlin ally Serbia is the only European country that has refused to align with EU sanctions following Russia’s full-scale invasion.
