Chief Executive Donald Tsang Yam-kuen repeatedly suggested Hunan companies list on the Hong Kong stock market as he ended a three-day tour to Changsha in Hunan province yesterday. He said although it was too soon to say whether the trip - on which he headed a 100-member delegation of businessmen and professionals from Hong Kong - had achieved any results, he knew some delegates had already found potential business partners in Hunan. He also believed the delegation had gained a better understanding of central China. Mr Tsang and the delegates returned last night. They visited leading construction vehicle manufacturer Sany Heavy Industry yesterday, where Mr Tsang asked chairman Liang Wengen whether he would raise funds and list in Hong Kong. One-third of cement trucks in Hong Kong are made by Sany, and the company's truck-mounted concrete pump was used during construction of Two IFC in Central. 'We are already listed on the Shanghai stock market but we're interested in [listing in Hong Kong],' Mr Liang said. 'In fact, we're dealing with some paperwork now.' Earlier yesterday, Mr Tsang visited Broad Air Conditioning and asked chairman Zhang Yue whether he too would raise funds and list on the Hong Kong stock market. Mr Zhang said investing in developed cities like Hong Kong would cost a lot of money. Although they visited Changsha for just three days, some delegates had already found business opportunities in Hunan and had targeted certain companies, Mr Tsang said. 'Some others are now actively considering investing in Hunan,' he said, adding that the government would help businesses in Hong Kong invest on the mainland. Vice-Premier Wu Yi, Mr Tsang and Macau Chief Executive Edmund Ho Hau-wah took part in the Central China Business Summit at Expo Central China 2006 yesterday morning. Expo Central China is the first trade fair for six central provinces where they can to promote their businesses. Ms Wu said developing central China had been a long-term goal for the mainland authorities. She urged the six provinces to seize the opportunities and turn their abundant natural resources into manufacturing power, but said they should also adhere to the laws. Mr Tsang took questions for the first time yesterday on former chief secretary Anson Chan Fang On-san's announcement last week that she would not run in next year's chief executive election. 'I think Mrs Chan's decision is a personal one and I think we need to respect her decision,' he said. 'But I believe it is not suitable for me to respond to it in the capacity of the chief executive.'
