On Monday, Kallas met with Zelensky during her first foreign visit of her new term, government spokespeople said.
The meeting took place in Zhytomyr and also involved the signing of a joint declaration.
"This is my first foreign visit as the head of the new Estonian government. I came here with a clear message that we believe in Ukraine's victory and we believe in Ukraine, which is a prosperous liberal democracy and a free market economy that belongs to the Euro-Atlantic family," Kallas said at a press conference after the meeting. "We remain committed to helping Ukraine win its war for freedom."
Kallas expressed hope that one of the first decisions of her new government to send Ukraine artillery shells will inspire other countries to quickly implement the European Union initiative, proposed by Estonia, to procure one million artillery shells for Ukraine.
"As President Zelensky has said, freedom must be better armed than tyranny. This is our common motto. Therefore, the aid focuses on weapons, ammunition and training -- there must be enough for Ukraine to win the war,” Kallas said.
In the joint declaration signed after the meeting, Kallas and Zelensky emphasize that a strong, independent and prosperous Ukraine is essential for European security as a member of the EU and NATO.
