Taoiseach Micheál Martin told President Volodymyr Zelensky that Ireland remains open to taking part in any peacekeeping mission in Ukraine.
He made the comments during a phone call with Mr Zelensky this afternoon.
They discussed the most recent developments aimed at securing a ceasefire and lasting peace in Ukraine, as Russia continues its attacks on the country.
The Taoiseach gave assurances to Mr Zelensky of Ireland's support for Ukraine.
"I assured President Zelensky that Ireland stands ready to support this work, including through the provision of non-lethal military assistance and our openness to taking part in any appropriately mandated peacekeeping mission in line with the UN Charter," Mr Martin said.
He added: "We will also continue to work with partners to support Ukraine's path towards EU membership."
Mr Martin and Mr Zelensky also discussed the need to keep pressure on Russian President Vladimir Putin, including through the use of further EU sanctions against Russia.
The Taoiseach expressed his condolences over recent deadly Russian attacks that have killed residents of Kyiv, including children.
"I expressed my view that recent attacks by Russia are a clear demonstration that President Putin is not interested in peace, despite the efforts of the international community to advance negotiations.
"The deliberate targeting of civilians, as we have seen in Kyiv, is a war crime and I extended my deep condolences to President Zelenskyy for the devastating loss of life, especially of children," Mr Martin said.
