Plans to build a 50,000-square-metre exhibition centre at Chek Lap Kok are being studied by officials. The multi-purpose centre, which would be built by around 2005, would cater for the growing need for conference and exhibition space in the next 10 to 20 years, the Government says. Legislators believe immigration controls should be eased to attract short-term visitors to the centre. Choy So-yuk, of the Hong Kong Progressive Alliance, said visitors to the proposed centre should be granted visa-free entry to the SAR. Secretary for Economic Services Stephen Ip Shu-kwan said Ms Choy's suggestion would be in line with government policy of promoting the tourist industry. 'We will review the immigration process and simplify it in order to give more convenience to the tourists and exhibition-goers,' he said.
