Chairman of Cheung Kong (Holdings), Li Ka-shing, yesterday denied that he had proposed a Hong Kong-Shenzhen tax-free trade zone for his own personal interests. Mr Li's clarification followed endorsement of the plan earlier this week by Financial Secretary Henry Tang Ying-yen and Guangdong Governor Huang Huahua. 'I have always been doing this for Hong Kong people,' Mr Li said. 'I am not seeking for my own benefits. I just wanted to see Hong Kong becoming better.' Mr Li, who put forward the plan to President Hu Jintao during a meeting in September, said it was encouraging that the government had given its support. Mr Li had proposed that the conversion of the kilometre square border area into a free-trade zone to attract investment and ease unemployment in Hong Kong. The idea was originally rejected by Secretary for Commerce, Industry and Technology, John Tsang Chun-wah, who said Hong Kong should not turn the clock back to the time of plastic-flower manufacturing. Soon afterwards, Chief Executive Tung Chee-hwa admitted he had held talks with Mr Li on the idea. Mr Tang also said this week that the government was considering allowing Shenzhen residents to enter the zone without a visa. Meanwhile, Mr Li said Hutchison would roll out third generation mobile phone services in the next few weeks. 'It will come out very soon, perhaps in two to three weeks' time,' he said. 'Right now, about 1,000 technicians had been working on the very last technical problem, which is a small one.'
