"The president noted that Türkiye is ready to host the next round of talks in a trilateral format. We appreciate this initiative and hope it can produce results," he wrote on social media.
Zelenskiy added that prisoner of war swaps and a possible leaders' summitwould be discussed during the next round of US-brokered talks between Ukraine and Russia.
He told reporters in a WhatsApp media chat that the talks had been postponed until next week.
US special envoy Steve Witkoff, a top adviser to President Donald Trump, said in a CNBC interview on Tuesday that the next round of trilateral peace talks would likely be "sometime next week".
Meanwhile, six civilians were killed and 37 injured in a Ukrainian missile attack on Russia's Bryansk region, governor Alexander Bogomaz said on Tuesday.
Zelenskiy said Ukraine's military hit a Russian missile plant in Bryansk.
"The operation targeted the Bryansk plant, which manufactured control systems for all types of missiles used by the Russian Federation," Zelenskiy told reporters on WhatsApp.
A United Nations investigation concluded on Tuesday that Russia's deportation and transfer of Ukrainian children since 2022 amounted to crimes against humanity.
Ukraine says close to 20,000 children have been illegally sent to Russia and Belarus where they are sometimes subject to military training and forced to fight against their own troops.
The International Criminal Court has issued arrest warrants for President Vladimir Putin and five other Russians over illegal deportation of children.
Russia denies it is taking children against their will, saying it has been relocating people voluntarily to remove them from a war zone.
"In this report, the Commission concluded that crimes against humanity and war crimes by Russian authorities have targeted children, who are among the most vulnerable victims," the report said.
"These crimes have irreversible consequences on their lives and their future."
The report by the Independent International Commission of Inquiry on Ukraine studied the cases of 1205 children from five regions in Ukraine and said that 80 per cent of them have yet to return.
Its work is based on analysis of thousands of documents and submissions from rights groups as well as over 200 interviews, including with families of the missing and some children who made it home.
"The deportations and transfers have originated from various locations across a wide geographic area in Russian-occupied areas in Ukraine, following a well-established pattern of conduct, indicating that these acts have been widespread and systematic," added the report, to be presented to the UN Human Rights Council in Geneva on Thursday.
It also said that Russian authorities at the highest level of government have helped co-ordinate the actions.
Ukraine's Foreign Minister Andrii Sybiha welcomed the report and called on countries to increase pressure on Russia to secure the return of deported children.
US-funded research last year showed Russia expanded its forced re-education programmes of deported children.
US first lady Melania Trump has advocated for their release and has been in touch with Putin's team as part of her work.
