"I believe in this. Otherwise, I wouldn't have run for Ukrainian presidency. This is very difficult, and here we need the help of the whole world, it's true. But I don't lose faith," Zelensky said.

"When there is such a need, we speak directly," the president explained. Zelensky also assessed the relationship with Russia and told whether he was in favor of normalization.
