An impasse of nearly two years in talks between China and Taiwan was broken yesterday as senior officials from Taipei began a 10-day ice-breaking visit to the mainland. The importance of the delegation was reflected in its four consultants - two from the Mainland Affairs Council and two from the Straits Exchange Foundation, Taiwan's two China policymakers. They include the foundation's deputy chief, Lee Ching-ping and Shieh Fu-yuen, deputy in the legal services department. The council is sending its legal department head Lui De-hsun and the department's researcher, Chang Hsien-chao, as consultants. The 14-member delegation from Taiwan's Institute of Notaries Public is led by its senior control committee member, Wu Chi-peng, who is also civil department head of Taiwan's Supreme Court. It is the highest level semi-official exchange between Taiwan and China since President Lee Teng-hui visited the United States in June 1995. Before his departure, the foundation's Mr Lee said he did not rule out a meeting with senior officials from its Beijing counterpart, the Association for Relations Across the Taiwan Strait. The delegation is due to meet China's Ministry of Justice and Association of Notaries Public today. Problems on cross-strait documentation will be on the agenda. They leave Beijing on Friday for Zhengzhou, Chengdu and Shanghai.
