Updated at 3.21pm: Financial Secretary Donald Tsang Yam-kuen gave his personal seal of approval to the controversial Disney project at a conference on Monday morning. Mr Tsang, soon to be head of the civil service, did not touch on potential environmental threats posed by the mega-project and called on the tourism industry to get into gear to prepare for a predicted bonanza, a Government spokesman said. While he acknowledged that bringing Disney to the SAR would cost the tax payer an estimated $22 billion, Mr Tsang, speaking at the Preparing for Hong Kong Disneyland Conference, said the project would bring in an estimated $148 billion into Hong Kong's economy over a 40-year period. ''I have absolutely no doubt that Hong Kong Disneyland will be a tremendous asset for our community. It will help consolidate and enhance our position as the region's Number One tourist destination as well as a major international city. It will enrich our commercial culture and business practices and introduce new cutting edge technology at a time when Hong Kong is positioning itself as a centre for innovation and technology in the Asia-Pacific region.''
