Wu Ching-kuo (
Wu won the vote 83 to 79.
``This is the most significant moment of my life,'' said Wu, a 60-year-old architect and AIBA's head for the next four years.
Wu is also Taiwan's representative on the International Olympic Committee (IOC).
Before the votes were counted, Wu's supporters handed out brochures to delegates outlining his platform of increased marketing, new television contracts and installation of scoreboards to make scoring more transparent.
Wu previously served as an AIBA committee chairman, and is a former Taiwanese basketball player.
He had the support of the US, delegation member Charles Butler said.
Wu also said he had the support of China, with whom he has worked on the 2008 Olympic Games.
His supporters said that Wu's victory was needed to keep boxing as an Olympic sport after years of controversy.
