A former senior Taiwan official has been denied a visa to attend an academic conference in Hong Kong amid the tensions across the Taiwan Strait. The Government rejected a visa for Chang King-yuk, a former chairman of the cabinet-level Mainland Affairs Council, on Monday. Frederick Fung Kin-kee, general education co-ordinator of the University of Hong Kong, said that in early June it had invited Mr Chang to give a speech on the unification of China. Mr Fung said immigration officials had given no reasons why the application was rejected. Officials said it was an individual case and did not imply Mr Chang would not be given a visa in future. Government officials would not comment. Mr Fung attributed the denial to the tension over Taiwan President Lee Teng-hui's stance that relations between the mainland and the island were 'state-to-state'. Mr Chang last visited Hong Kong in May last year in a personal capacity, although he was still chairman of the Mainland Affairs Council. Asked about Mr Chang's case, National People's Congress Standing Committee member Tsang Hin-chi said he had been denied entry to Taiwan since 1987. 'I applied once after I became an NPC local deputy but it was rejected. Then I did not apply again,' he said. The Goldlion Holdings chairman has also folded his business in Taiwan. China analyst Johnny Lau Yui-siu said neither Taiwan nor the mainland were not sincere in trying to communicate with each other. He said Hong Kong could become a conduit point for the two governments to exchange their views formally or informally. But the governments had done less since the handover. Hong Kong was passive and caught in the middle of the tense situation.
