Smart City Development in Kowloon East KE consists of the former airport site – the Kai Tak Development area, the Kwun Tong and Kowloon Bay Business Areas. Since the closing of the airport, the relocation of manufacturing industries to the Mainland and the rapid increase in demand for high grade office buildings, KE has been rapidly transforming. The Government advocates the transformation of KE into another core business district (CBD2) to support Hong Kong’s economic development by adopting a visionary, coordinated and integrated approach. Smart city development can play an important role in this process by offering innovative and sustainable urban development solutions. Read more about The Quayside development in this section.
