In 2016, Chui was caught up in allegations of transferring Macau's reserves to the mainland. 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. The Macanese government said that the donation was made in return for China's long-standing support to the SAR.
