Political career
Chiang was elected to the Legislative Yuan in 2001 and was selected vice president of the legislature, a post he held until the Fifth Legislative Yuan adjourned in 2005. Chiang was re-elected to the Legislative Yuan in 2004 but did not take on the vice president post, which went to the KMT's alliance People First Party. There were ongoing negotiations for Chiang to join the cabinet of Premier Frank Hsieh as vice premier, but talks fell apart between the KMT and the administration over Chiang's specific responsibilities for the post. In March 2005, Chiang led the KMT's first official delegation to mainland China since the end of major hostilities in the Chinese Civil War in 1949. The delegation paid homage to the 72 martyrs of the Tenth Revolution in Huanghuagang before travelling to the Sun Yat-sen Mausoleum in Nanjing and to Beijing. During the trip, Chiang promoted opening the three links and economic development. On 14 March 2007, Chiang became acting chairman of the KMT after Wu Po-hsiung, who had been acting chairman since Ma Ying-jeou's resignation earlier in the year, resigned the acting chairmanship so that he could run for chairman in the upcoming party election.
Straits Exchange Foundation
Following the Kuomintang's landslide win in the presidential election in 2008, Chiang was designated as chairman of the Straits Exchange Foundation, the semi-official body responsible for negotiation on non-political matters with the People's Republic of China. This made him responsible for the front line negotiations with the PRC government. He stepped down from this position in 2012.
