Wu has been an advocate for more than two decades for the construction of Asia's largest bridge project linking Hong Kong, Macau, and China's Zhuhai city. The Hong Kong-Zhuhai-Macau Bridge project was given support by the PRC government in August 2003. The bridge will traverse two-man-made islands, allowing it to go through an undersea tunnel and let shipping pass. The concept is based on the existing Chesapeake Bay Bridge-Tunnel in Virginia, United States.
Gordon Wu has spoken out in opposition to the development of democracy in Hong Kong. He joined more than 80 of Hong Kong's richest business tycoons and their heirs apparent headed for Beijing on 26 September 2003 on an annual pilgrimage. The same year, he told the Chinese University of Hong Kong executive MBA programme that he opposed direct elections in Hong Kong which, he believed, would cause many problems. Noting that only 10 per cent of Hong Kong citizens pay taxes, with the remaining 90 per cent receiving subsidies in various forms, e.g., public housing, healthcare, and education, if direct elections were introduced, this group would, with the help of the politicians they had voted in, "get not only free lunches, but free dinners and breakfasts."
