A BEIJING-SPONSORED academic conference to promote better understanding and mutual trust between China and Taiwan was transformed into a forum against Taipei's advocacy of ''one China, two political entities'', participants said. The organisers - Institute of Taiwan Studies of the Chinese Academy of Social Sciences, All-China Federation of Taiwan Compatriots and All-China Association of Taiwan Studies - altered a paper by a Taiwanese participant without his consent. Terms like ''Republic of China'' and ''ROC Government'' were changed to ''Taiwan'' and ''Taiwan authority'' respectively. And instead of referring to Lee Teng-hui as the Taiwan President, the organisers simply dropped his title. The author of the altered paper, Wu An-chia, a research fellow of the Institute of International Relations of Taiwan's National Chengchi University, said: ''It is not right that they deleted these terms without my consent.'' This year's conference was particularly significant because it was the first gathering of Taiwanese and mainland academics since the Qiandao Lake murders. Mr Wu, who also took part in the 1992 conference, said the alternations appeared to be a departure from previous practice. He said he lodged a complaint on the first day of the three-day conference, but the organisers said the ''technical'' changes had been made for the sake of a more ''harmonious atmosphere during discussions''. While China's official media portrayed the conference positively, saying that many ''helpful opinions and proposals'' had been put forth by the ''pragmatic'' and ''rational'' participants, Mr Wu felt otherwise. ''There were too many disagreements,'' he said. These included Taiwan's bid for readmission to the United Nations and the issue of ''two political entities'', Mr Wu said. Although Taipei agreed that there is only ''one China'', the Kuomintang Government holds that Taiwan and the mainland are ''two political entities'', neither of which has jurisdiction over the other. Mainland participants at the conference argued that Taiwan was in effect advocating ''two Chinas'' or ''one China, one Taiwan'' under the disguise of ''one China, and two political entities''. Some Taiwan participants were particularly frustrated by the emotional wordings their mainland counterparts used when criticising the Taiwan President and his policies towards the mainland, Mr Wu said. Xinhua (the New China News Agency) yesterday quoted the director of the Party Central Committee's Office for Taiwan Affairs, Wang Zhaoguo, as reiterating Beijing's policy of ''one country, two systems'' and peaceful reunification.
