Many issues affect the direction of Cross-Strait relations. In Chapter 5: The Issues of the e-book, it examines the key factors that have the greatest bearing on relations between China and Taiwan. In the Issues section on the website, we further investigate the factors as well as other factors affecting the direction of cross-strait ties. The Key Issues include the concept of One China, which contains five interpretation; the fact that the PRC wants Taiwan to reunify under the one country, two system formula; the refusal of the PRC to renounce the use of force against Taiwan to resolve issues; the passage of the 2005 PRC Anti-Secession Law; U.S. arms sales to Taiwan; the long-standing position of the Democratic Progressive Party (DPP) on Taiwanese Independence; the DPP's interpretation of the status quo compels the current DPP president, Tsai Ing-wen, to refuse to verbalize the 1992 Consensus. Similar to the concept of 'one China', the status quo also contains different interpretations which both sides of the strait now actively promote. Against this backdrop, the Key Issue section further investigates the factors affecting cross-strait relations in order to provide the researcher with access to a wide range of resources, with a priority on providing you with the official documents collected from reliable sources.
