On 25 February 2022, the day after the Russian invasion, President Zelensky argued: "Today we heard from Moscow that they still want to talk. They want to talk about Ukraine's neutral status.… We are not afraid to talk about neutral status".

On the next day, 26 February, Zelensky reaffirmed his preparedness to negotiate about Ukraine’s neutrality: “If talks are possible, they should be held. If in Moscow they say they want to hold talks, including on neutral status, we are not afraid of this. We can talk about that as well.”

On 25 February 2022, the first day after the Russian invasion, even as Zelensky agreed to discuss neutrality, US spokesperson Ned Price announced Washington rejected any peace talks without preconditions as he insisted the US could not accept diplomacy before Russia withdrew all its forces from Ukraine:
“Now we see Moscow suggesting that diplomacy take place at the barrel of a gun or as Moscow’s rockets, mortars, artillery target the Ukrainian people. This is not real diplomacy… If President Putin is serious about diplomacy, he knows what he can do. He should immediately stop the bombing campaign against civilians, order the withdrawal of his forces from Ukraine, and indicate very clearly, unambiguously to the world, that Moscow is prepared to de-escalate.”

On 21 March 2022, US spokesperson Ned Price suggested that a diplomatic settlement was not entirely up to Ukraine as it was also a conflict about world order:
"This is a war that is in many ways bigger than Russia, it’s bigger than Ukraine…. The key point is that there are principles that are at stake here that have universal applicability everywhere, whether in Europe, whether in the Indo-Pacific, anywhere in between".
