During the conversation, Borrell confirmed the EU's full solidarity with Ukraine.
Kuleba thanked him for his personal leadership and support over the past two years.
"The EU has made historic decisions on providing weapons to Ukraine, imposing sanctions on Russia, launching Ukraine's EU accession talks, and supporting Zelenskyy's Peace Formula. Many improvements and decisions are still ahead and we are working together to ensure their quick adoption," the Ukrainian Foreign Minister said.
He stressed that the absolute priority now is artillery shells.
"Artillery shells are the absolute priority right now. By the end of March, the EU plans to deliver almost 170.000 rounds to Ukraine and is working to further increase the volume of deliveries," Kuleba said.
