The desirability of joining regional integration in an age of globalization is often measured in materialistic terms, and ideological issues such as values, believes and identities are either dismissed or ignored. This paper aims to argue that common values and believes are critical not only to intra- but also to inter-regional integration, by looking into the historical ex-periences of European integration. This paper distinguishes four different integrative models of EU members` participation in European integration from empirical evidences and ana-lyzes their implications for European integration and regional cooperation between the EU and Asia. It argues that, for European integration, a recall and reviving its commitment to common values and believes have become imperative especially at a time of crisis. For the EU-Asia cooperation, the task of searching for common values and believes should not be ignored any longer, especially after the negotiations on ASEAN-EU FTA collapsed. If the inertia of slow and stagnant developments of EU-Asia integration is meant to reverse, policy-makers must answer a key question first: what are the common values and believes between the two communities?
