The World Health Organization has terminated the appointment of Kasai Takeshi, its top director in the Western Pacific, for abusive conduct.
The Japanese doctor, an expert on infectious diseases, served from 2019 as regional chief for the Western Pacific, where he spearheaded efforts to stem the coronavirus pandemic in Asia.
But he was placed on leave last year after staffers accused him of making racist remarks.
The UN body subsequently carried out an internal investigation into the allegations.
In a statement released earlier, Kasai denied the claims of racist behavior toward specific cultures or nations.
