Taoiseach Simon Harris hugged Ukrainian President Volodymyr Zelenskiy as he landed in Ireland for a bilateral meeting.
It is their first bilateral meeting on Irish soil and is focused on Russia’s ongoing invasion of Ukraine.
Mr Zelenskiy landed at Shannon Airport in Co Clare at noon, and hugged Harris after descending the steps from his state aircraft.
The leaders also shook hands while Ukrainian ambassador to Ireland Larysa Gerasko was also present.
Asked by reporters for his message to Ireland, Mr Zelenskiy said: “First of all, thank you so much for your support, thanks to Ireland for hosting a lot of Ukrainian refugees, you were with us from the very beginning of the Russian invasion.”
Mr Zelenskiy was also asked about US President Joe Biden mistakenly referring to him as “President Putin”.
He replied: “It’s a mistake. I think the United States gave a lot of support for Ukrainians. We can forget some mistakes, I think so.”
While discussing the future of the conflict during the bilateral, Mr Harris expressed his condolences for the citizens whom Ukraine has lost in the war including the bombing of Ukraine’s largest children’s hospital earlier this week.
He also expressed Ireland’s full support for Ukraine’s bid towards EU membership.
Mr Harris, who became Taoiseach in April, offered further assistance for thousands of Ukrainian children forcibly relocated to Russia and Belarus and entered into Russian re-education programmes since the war began.
He confirmed Ireland’s membership of an international coalition for the return of the estimated 20,000 children.
The two leaders last met on the fringes of the Ukraine Peace Summit in Switzerland in June.
Mr Zelenskiy is stopping at Shannon Airport on his way back from a summit marking the 75th anniversary of Nato in Washington DC.
Ireland has provided €250 million in non-lethal military assistance to Ukraine under the European Peace Facility and the country has welcomed over 108,000 Ukrainians under the EU Temporary Protection Directive.
Irish Defence Forces members have trained 455 Ukrainian personnel in demining, battlefield casualty care and the use of non-lethal mine clearance equipment.
