This study aims to illuminate the interactive relationship between domestic politics and external policy in Taiwan's mainland China policy after the 2000 presidential election. Following the logic of Putnam's two-level games, this paper demonstrates how the newly elected President Chen Shui-bian adopted an ambiguous and evasive approach as well as frequently shifted positions in his dealings with the mainland China issue due to the constraints of his pro-independence constituents and a vigilant, anti-independence Beijing. Employing Knopf's three-to-three games as well as Puchala's issue politicization, it further shows how Taiwan's opposition parties--the KMT, the PFP, and the NP--as well as Chen's political rivals, took advantage of Chen's inability to break the Strait impasse by initiating active engagement with Beijing in order to gain political advantages.
