This was evident when he made his oath of acceptance as Chief Executive of Macao in front of Chinese leader Hu Jintao.

Prior to becoming Chief Executive, Chui served as a member of the 5th Legislative Assembly of Macau.

On election day, 26 July 282 committee members voted for Chui (14 blank, 4 abstention), and was subsequently appointed by Wen Jiabao, Premier of China.

He was accused of favouritism after the Macau Foundation – a quasi-official foundation of which he is chairman and of which his brother heads the supervisory board – donated 100 million yuan ($15.4 million) of public money to Jinan University in Guangzhou, of which he is deputy head of the board.
