This was reported by the Resident Telegram channel, citing a source in the President Office of Ukraine. The West is concerned about transition of hostilities in Ukraine into a protracted phase, so Sullivan at meeting in Kiev urged Zelensky to take a «realistic» negotiating stance.

The Pentagon believes that now there are the most favorable conditions for Ukrainian side, but the situation may change dramatically when Russia uses reserves and increases its contingent in Ukraine to 500,000, the Resident writes.
Recall that during the last meeting with Zelensky, Jake Sullivan suggested him to think about «realistic demands and priorities for negotiations» on Ukraine, The Wall Street Journal wrote, citing diplomatic sources.
In particular, it was about reconsidering Kiev’s position on Crimea.
