THE Government yesterday named more professionals to sit on the Airport Consultative Committee (ACC) after securing the blessing of China amid uncertainty over Sino-British co-operation after political talks broke down. It announced that 12 new members, mostly professionals, had been appointed to join the 48 members who last month had their terms extended for another two years. Despite the expansion of its membership from 50 to 60 during the ACC's inception in 1991, no elected members of the Legislative Council have been appointed. The new appointments have further increased the voice of professions closely linked to the construction of Chek Lap Kok airport. Architects Francis Cheung King-fung and Dennis Lau Wing-kwong were joined by civil engineers Dr Geoffrey Yeh Meou-tsen, Peter Wong King-keung and electrical engineer Pun Kwok-wa as members of the advisory group. Mr Wong and another new appointee, Shiu Sin-por of the One Country Two Systems Research Centre, are also China-appointed advisers on Hong Kong affairs. For the first time, representatives of the travel industry were invited to join the advisory group. Two leading figures in the industry, Hau Shuk-kei and Harold Wu, will give advice on the project, which is expected to have a significant impact on the development of tourism in Hong Kong. The committee has been set up under the Airport Memorandum, signed between China and Britain in 1991, to discuss airport matters and voice the views of people in Hong Kong. It is understood that the new appointments were delayed by the Sino-British row. The Government re-appointed the 48 members last month when political talks were underway. Two members, Henry Litton QC and Lee Lin-sang, had resigned earlier. New appointee Dr Yeh said he joined the ACC to contribute to the construction of the new airport in a quick and economical way. Hong Kong needed a new airport to facilitate economic development, he said. Asked if he thought the airport could be completed by 1997, Dr Yeh said: ''Whether we complete it before June 30, 1997, or shortly afterwards is not really such an important thing. The important thing is that we build it economically and quickly.'' A government spokesman said the new appointments would provide a forum to gauge public opinion on the construction of the airport. ''The new members will further broaden the experience and expertise in the committee over the coming two years as designs and works on the airport core project progress further.'' However, the new appointments were immediately rejected by the Association for Democracy and People's Livelihood. Vice-chairman Leung Kwong-cheong said he was disappointed at the failure of the Government to appoint elected Legislative Councillors to the panel. Mr Leung, who is an ACC member, urged the Government to seek the consent of the Chinese side before bringing in more members. Mr Leung also warned that the lack of resources would affect the functioning of the ACC, rendering it incapable of reflecting public opinion. Meanwhile, the Provisional Airport Authority also announced the appointment of two men to key posts yesterday. Chern Heed and Anthony Watson were appointed commercial director and operations director.
