As the political climate in Taiwan grew less oppressive and more open, the DPP flourished and began competing with the KMT in elections. In the early 1990s, Chiou was appointed Secretary General of the DPP and served under party Chairmen Shih Ming-teh and Hsu Hsin-liang, but resigned from the post in 1998 to take responsibility for the poor performance of the DPP in the three-in-one elections. The DPP had also begun sending its own representatives to the United States, so as to counterbalance the views of the official KMT-run Taipei Economic and Cultural Representative Office. Subsequent to his resignation as DPP Secretary General, Chiou was appointed DPP representative, and was sent to Washington, DC.
