A planned visit to Taiwan by Chen Yunlin , director of the mainland State Council's Taiwan Affairs Office (TAO), appeared doomed yesterday after Taipei insisted that the application had to go through 'necessary negotiation procedures'. Taiwan's Mainland Affairs Council chairman Joseph Wu Jau-shieh yesterday said prior negotiations between the governments of the two sides were a must. Mr Wu said a planned visit by a high-level official like Mr Chen had to go through official negotiation procedures to ensure all arrangements were proper and that there would be no safety problems during his stay in Taiwan. He said if there were no government-to-government talks, at least the proxy agencies of the two sides - Taipei's Straits Exchange Foundation and Beijing's Association for Relations across the Taiwan Strait - had to do the talking. Mr Wu's demand for government-level talks meant the chances of Mr Chen visiting had become slimmer because Beijing, which considers Taiwan an integral part of the mainland, refused to talk with the independence-leaning Democratic Progressive Party government, political analysts said. Mr Chen was invited to visit Taiwan and attend a high-level political party forum in Taipei in mid-December by the main opposition Kuomintang, which applied to government authorities for the TAO director to visit. Mr Wu said that in the current political atmosphere, it was improper for any Taiwanese political groups to claim to represent the mainland in talks with the DPP government. But Mr Wu welcomed a scheduled Friday visit by the mainland National Tourism Administration director-general Shao Qiwei , saying his trip would pave the way for Beijing allowing tourists to visit the island, giving mainland people a chance to understand Taiwan's freedom and openness.
