Taiwan's efforts to take part in international organisations (IOs) have received little backing from the international community owing to Taiwan's contested sovereignty. This article investigates under what circumstances and how the European Union (EU) supported Taiwan's participation in IOs and agreements by examining the role of the EU in three success stories: the World Trade Organization (WTO), the Government Procurement Agreement (GPA) and the World Health Organization (WHO). The analysis of six factors that shaped the EU's approach shows that a strong EU interest in Taiwan's IO participation was a precondition for its support and that once this precondition was met, applicable membership/participation criteria and opportunities for circumventing or neutralising China's opposition then gained in importance. A supportive United States (US) stance could function as a trigger for EU support. Two counterintuitive findings are that the radicalisation of Taiwan's own strategy fostered increased EU activity in brokering compromises between Taiwan and China and that the EU's decision-making mechanisms did not play a decisive role in the formulation of its support policies.
