A VICE-CHAIRMAN of the National People's Congress (NPC), Wang Hanbin, is tipped to head the body which will prepare for the establishment of the powerful Special Administrative Region (SAR) Preparatory Committee. Hongkong advisers to Beijing, and Hongkong deputies to the NPC have been invited to join the body, known as the working organ, it has been learned. Chinese sources said yesterday that the central leadership had proposed nominating Mr Wang, 67, alternate member of the Politburo and chairman of the NPC's Law Committee, as chairman of the working organ when the NPC Standing Committee meets this month. The Standing Committee will discuss how to set up the working organ. The SAR Preparatory Committee will set up the first post-1997 government and legislature. Sources said Mr Wang was regarded as one of the most appropriate candidates because of his seniority, his legal expertise and knowledge of the Basic Law. Mr Wang, a former vice-chairman of the Basic Law Drafting Committee, is overseeing legal matters involving the handover of sovereignty and the implementation of the Basic Law before and after 1997, sources said. They said not less than half the members of the working organ would be Hongkong people, selected from the Hongkong affairs advisers, Hongkong deputies to the NPC and the Chinese People's Political Consultative Conference (CPPCC) and those involved in drafting the Basic Law. The pro-Beijing Hongkong Commercial Daily reported yesterday that Henry Fok Ying-tung and Ann Tse-kai, both vice-chairmen of the CPPCC, would be vice-chairmen. The report said Lu Ping, director of the State Council's Hongkong and Macau Affairs Office and Zhou Nan, local New China News Agency (NCNA) director, would also be vice-chairmen. Mr Fok said that if he were formally offered the post, he would seriously consider it. He said China had been preparing to set up the working organ. ''There is plenty of preparation work needed to prepare for the handover,'' he said. Zhang Junsheng, vice-director of the NCNA, said yesterday the working organ should be set up as soon as possible to make for a smooth transition. ''There are only four years and 20 days left before the handover on 1 July, 1997. I believe the NPC Standing Committee will set up the working organ as soon as possible,'' he said. Mr Zhang declined to confirm whether NCNA officials had begun to invite NPC deputies and Hongkong affairs advisers to join the body. He said there was no correlation between the establishment of the working organ and the talks on political reform. ''The working organ is aimed at preparing for the setting up of the SAR Preparatory Committee and the formation of the SAR government. ''The talks only focus on the electoral arrangements in 1994/95,'' he said.
