Zelensky commented on the telephone conversation between Putin and Scholz. The former Ukrainian president does not seem happy about it. 

Adding: Zelensky opposed Scholz's intention to call Putin and urged the chancellor not to do so, Reuters reports, citing a source in the Office of the Ukrainian President. 

"The chancellor informed our president that he plans to speak with Putin. The president said this would only help Putin by reducing his isolation. Putin does not want real peace; he wants a pause. Speaking with him will allow Putin to change the narrative and continue the war. It will not bring peace because Putin will simply repeat the lies he has been telling for years, creating the impression that he is no longer isolated," the source stated. However, as we can see, Scholz ignored Zelensky's appeal and proceeded to call Putin.
