President Sheikh Mohamed met Ukraine's first lady Olena Zelenska in Abu Dhabi on Tuesday.
Sheikh Mohamed said that $4 million would be directed to the Olena Zelenska Foundation, which will be used to contribute to the construction of 10 buildings that will house about 100 children, news agency Wam reported.
The foundation is helping people affected by the war, providing treatment to war survivors, helping in the reconstruction of schools, and sending aid to family-type orphanages and families that have adopted children.
Earlier in the day, Sheikh Mohamed held talks with Polish President Andrzej Duda.
The two leaders reviewed developments in Ukraine during their meeting at Al Shati Palace.
Mr Duda thanked Sheikh Mohamed for supporting Poland in hosting Ukrainian refugees, Wam reported.
More than one million Ukrainian citizens have crossed the border to seek sanctuary in neighbouring Poland since the Russian invasion.
