Zelenskiy said the United States had proposed hosting the next meeting between US, Ukrainian and Russian negotiating teams, which include US envoys Steve Witkoff and Jared Kushner, but Russia had refused to send a delegation.
"We are waiting for a response from the Americans. Either they will change the country where we meet, or the Russians must confirm the US," Zelenskiy said in a media briefing.
"We are not blocking any of these initiatives. We want a trilateral meeting to take place."
The US has postponed its sponsored talks between the two sides due to the war in the Middle East.
The Iran war, which erupted on February 28 following US-Israeli strikes on Iran and spread across the region, has drawn the international spotlight away from Ukraine's plight as it strives to hold back Russia's army.
Speaking to reporters, Zelenskiy also warned of a "very high" risk that the Iran war could drain the air defence stockpiles Ukraine depends on to counter Russian missile strikes.
Zelenskiy said he lacked a clear picture of available stockpiles and had discussed with French President Emmanuel Macron in Paris on Friday whether SAMP/T systems could serve as an alternative to US-made Patriot batteries for intercepting ballistic missiles.
He said Ukraine would be "first in line" to test any viable alternative.
He said he had offered the US a defence co-operation deal last year worth $35 billion–$50 billion that would have given the US administration access to technology from roughly 200 Ukrainian drone, AI and electronic warfare firms, with half of all production earmarked for partners, primarily the US.
According to the Ukrainian leader, US military officials had expressed strong interest in the proposal and US President Donald Trump himself had indicated he was receptive.
