Ukrainian President Volodymyr Zelenskyy said that Ukraine will not give up territory in the negotiations, and he deemed that fighting in the Donbas region could influence the course of the entire situation, during an interview with CNN.

He also believed that U.S. President Joe Biden should visit Ukraine, adding that he offered the same invitation to French President Emmanuel Macron during their phone talk last week, "I invited him to come when he will have the opportunity. He'll come and see, and I am sure he will understand."

Zelenskyy acknowledged foreign military aid was helpful, but Ukraine still needed more and faster weapon delivery into Ukrainian's hands.

"We are prepared to use any type of equipment, but it needs to be delivered very quickly. And we have the ability to learn how to use new equipment. But it needs to come fast," Zelenskyy said.
