MEMBERSHIP of the working committee preparing for the territory's Special Administrative Region (SAR) government could be expanded, according to the top Chinese official in charge of Hongkong affairs. Meeting Point members, speaking on their return from Beijing yesterday, said Lu Ping - the Director of the Chinese State Council's Hongkong and Macau Affairs Office - had confirmed that the 57-member body could be expanded if needed. Meeting Point chairman Anthony Cheung Bing-leung said their meetings with Chinese officials had focused on preparations for 1997. Noting that Beijing had failed to acknowledge the representativeness of the Legislative Council they had urged China to heed the views of legislators and called for the public to be given more access to Hongkong advisers, deputies to the Chinese People'sPolitical Consultative Conference and to the National People's Congress. ''Democratisation is a need for Hongkong people and we hope the Chinese Government will adopt an open and positive attitude to Hongkong's political development,'' Mr Cheung said. But Mr Lu had told them democratisation should not be too fast.
