Ukrainian President Volodymyr Zelenskyy announced Saturday that Ukraine is "still prepared" to proceed with dealings with Moscow, which have slowed down since the revelation of barbarities in Bucha and different regions close to Kyiv.

"Ukraine has always said it is ready for negotiations and looking for any way to stop this war," Zelenskyy said in a press conference with the Austrian Chancellor Karl Nehammer, who visited Bucha.

"Sadly, in parallel we see the preparations for important battles, some people say decisive ones, in the east," he said, referring to an anticipated Russian offensive.

"We are ready to fight and to look in parallel to end this war through diplomacy," he added.

The last face-to-face talks between the two sides took place on March 29, during which Ukrainian negotiators are said to have signaled their readiness to accept neutrality in return for security guarantees from third parties.

"In the east and in the south, we have seen a concentration of arms, equipment and troops who are getting ready to occupy another part of our territory," Zelenskyy said.

The outcome of any new Russian offensive would depend "on several factors," he said, including Ukraine's "strength, how quickly our partners supply us with arms, and the Russian leader's (Vladimir Putin) desire to go further."
