U.S. President Joe Biden believes that Ukraine itself should decide whether to make territorial concessions for the sake of a ceasefire, but does not believe that Ukraine will have to agree to this.

"That is a total judgement based on Ukraine. Nothing about Ukraine without Ukraine. I do not believe that they will have to do that. These are judgements of negotiations, discussions, that taking place I am not a part, including Ukrainians. It is their judgement to make," Biden told the press conference in Brussels on Thursday.

That was Biden's answer to a journalist's question about whether Ukraine should make territorial concessions in order to achieve a ceasefire.
