Russian President Vladimir Putin said after hearing a report from the head of the Russian negotiating delegation, Mejinsky, that Russia will not accept the 30-day or 60-day ceasefire proposed by Ukraine. Putin said that this move will give Ukraine a respite and rearm. Mejinsky reported to Putin that the Ukrainian side proposed to implement a 30-day or 60-day ceasefire first in the negotiations, and the two sides used the ceasefire period to prepare for a peace summit. Mejinsky said that the Russian side is ready to start the exchange of 1,200 prisoners with the Ukrainian side on June 7-9, which will be the largest exchange of prisoners.
