Ukrainian President Volodymyr Zelensky will meet Taoiseach (Irish prime minister) Simon Harris at Shannon Airport on Saturday.
It will be the first bilateral meeting with Mr Zelensky in the Republic of Ireland and will focus on Russia's ongoing invasion of Ukraine.
The Press Association understands Mr Harris is expected to express his condolences for Ukrainian citizens killed in the war.
It comes after the country's largest children's hospital was bombed earlier this week.
It is understood Mr Harris will also express the Republic's full support for Ukraine's bid towards European Union membership.
The taoiseach will also offer further Irish assistance for thousands of Ukrainian children forcibly relocated to Russia and Belarus and entered into Russian re-education programmes since the war began.
