Wu Jiezhuang, a member of the National Committee of the Chinese People's Political Consultative Conference in Hong Kong, a member of the Hong Kong Legislative Council and chairperson of the Subcommittee on Web3 and Virtual Asset Development, pointed out that in order to solve the bottlenecks in the development of the digital economy such as the difficulty of financing for small and medium-sized enterprises in the mainland and the inefficiency of cross-border transactions, he suggested setting up a digital asset exchange fund in Hong Kong to provide digital asset mortgage financing for small and medium-sized enterprises in the Greater Bay Area of the mainland, and at the same time promote financial circulation in the Greater Bay Area. He also suggested promoting the establishment of a blockchain unified trading and settlement platform for licensed virtual asset trading platforms in Hong Kong,
