Chief Executive Donald Tsang Yam-kuen has urged the business community to take a more active and influential role in forming the government's policies. Speaking at yesterday's joint chambers of commerce luncheon, Mr Tsang called on business leaders with political ambition to 'take the plunge and get involved in running Hong Kong'. 'Greater involvement by all sectors in the running of Hong Kong is essential for better governance,' he said. The call follows Mr Tsang's appointment of senior business leaders to the Executive Council last week in his policy address. Mr Tsang said he wanted to expand the scope of business-to-government contacts and was keen to garner advice on policy decisions that would help Hong Kong continue to prosper. 'If we can make better use of the huge pool of specialised knowledge in the community, we can develop policies that dovetail more closely with society's needs and requirements,' he said. Cathay Pacific chief executive Philip Chen Nan-lok and Real Estate Developers Association chairman Stanley Ho Hung-sun welcomed Mr Tsang's business-friendly attitude. Mr Tsang also said the government would work on strengthening links to the international and mainland business communities and would continue to encourage people from all over the world to come and work in Hong Kong. After the luncheon, Mr Tsang lashed out at anti-globalisation protesters who disrupted Sunday night's open forum at the University of Hong Kong with new World Trade Organisation director-general Pascal Lamy and forced the cancellation of a press conference. The activists became rowdy when they were refused a meeting with Secretary for Commerce, Industry and Technology John Tsang Chun-wah. 'The Hong Kong government will ensure the protesters can express their opinion but we hope they are calm and rational,' he said. In a question-and-answer session, Mr Tsang defended the decision to build government offices on the Tamar site, saying the land needed to be used productively. 'This is a city that seems to have strong overdevelopment at the moment. But this is the very time when development is needed. I think a balance has to be struck. The whole harbour is being looked at, and every project we do is taken seriously, and I'm sure the right decisions are being taken,' he said.
