Taiwan said yesterday it had not applied to send a senior representative to the SAR because of 'unreasonable' restrictions. An official said the SAR had demanded that proposed representative Chang Liang-jen sign a 'supplementary document' along with the application. 'The language of this document demands the impossible from us and is very unreasonable,' said Tsai Jy-jon, director of the Department of Hong Kong and Macau Affairs under the Mainland Affairs Council. 'We cannot sign this document.' The document is said to include a denial that Mr Chang represents the Taiwan Government. The post of senior representative has been vacant since December, when the SAR refused to renew the visa of the incumbent, Cheng An-kuo, who aroused criticism from pro-Beijing politicians for defending Lee Teng-hui's 'two-states theory' on RTHK. Mr Chang is currently deputy secretary-general of the Straits Exchange Foundation. His official title in Hong Kong would be head of the Chung Hwa Travel Service, Taipei's quasi-official representative body. He said yesterday he was still optimistic about being able to come to the SAR. 'I hope I can take up my new post in Hong Kong pretty soon, for promotion of relations between Taiwan and Hong Kong,' he said. 'So it's a puzzle for me, but I hope it can be solved pretty soon.' An SAR source said a demand for Mr Chang to relinquish all official posts before coming to Hong Kong was in line with pre-handover practice. 'They [Taipei officials] are trying to seek more space,' the source said. 'You can't expect the Government to make any concessions on the question of 'one country'. The Taiwanese authorities have breached the rule of confidentiality by disclosing the Government's demands to the media. We don't want megaphone diplomacy, but discussions through representatives.' The source disputed claims by Taipei officials that the stalemate had damaged links between the two sides. Figures showed that the number of Taiwan visitors to the SAR had grown faster than Taiwan-bound local visitors, he said. 'The Government has done a lot to make it easier for Taiwan people to visit Hong Kong. But the rules for Hong Kong people to travel to Taiwan have not been relaxed much,' the source said. A government spokesman said: 'We are waiting for their response and formal application.'
