Democratic Progressive Party (DPP) Secretary-General Su Jia-chyuan suggested Saturday that Chen Yunlin, president of the Association for Relations Across the Taiwan Straits (ARATS), must not travel around while in Taiwan to avoid giving the impression of 'conducting an inspection,' which could be provocative. Chen had previously expressed his desire to visit some victims of Typhoon Morakot while in Taiwan, but it remains unclear if any such trip has been arranged or if Su's advice will be taken. Accompanied by party officials from the DPP's branches in Taichung City and Taichung County, Su called on Taichung Mayor Jason Hu to discuss issues related to security and public order during the ARATS president's negotiations with Chiang Pin-kung, chairman of Taiwan's Strait Exchange Foundation, from Dec. 21-23 in Taichung. The DPP and some civil groups have mobilized their followers to launch a large- scale rally in Taichung Sunday and other protest activities on the following days to express their appeal for transparency in cross-strait negotiations. Su told the Taichung mayor that the DPP will not be involved in any 'sabotaging' behavior. Over the past few days, Hu has repeatedly called on the DPP to prevent a repeat of the violent confrontation between protesters and the police that occurred last year during the second round of Chiang-Chen negotiations in Taipei. He has also cautioned policemen not to overreact when facing the protesting crowds. Expressing confidence in the mayor's wisdom to manage the situation, Su said the DPP, for its part, has set up a command center in Taichung City and party officials on duty will maintain communications with the city government to reduce the possibility of confrontation.
