Belgrade nominally supports Ukraine's territorial integrity and has provided humanitarian assistance, while Serbian-made ammunition has reached Ukraine through third countries. After the Zelensky-Vucic meeting, Vucic reaffirmed Serbia's nominal support for Ukraine's territorial integrity under the UN Charter, and Zelenskyy thanked Serbia for respecting Ukraine's sovereignty, including the status of Crimea. Montenegro, too, has felt significant Serbian political and informational, political and religious influence.
