The Unesco head said the agency had been preparing for Washington's move, diversifying its sources of funding. Currently, she said, Unesco was getting about 8% of its budget from the US.

In 2017, during his first presidency, Trump pulled the US out of Unesco but the decision was later reversed under Joe Biden's administration.

The Paris-based UN agency was set up in November 1945 - shortly after World War Two - to promote peace and security through global co-operation in education, arts, sciences and culture.
