Volume 8 of the EYIEL focuses on the external economic relations of the European Union as one of the most dynamic political fields in the process of European integration. The first part of this volume analyses the recent controversial questions of the external economic relations of the Union, dealing with the complexity of mixed agreements, transparency and legitimacy issues as well as recent proposals in relation to Investor-State-Dispute Settlement, the Trade Defence Instruments and the implications of the “Brexit” in this context. The second part of EYIEL 8 addresses ongoing bilateral and multilateral negotiations of the EU with China, Japan, Australia, Canada and Taiwan. Moreover, the third part deals with the EU in international organisations and institutions, in particular the recent institutional aspects of the EU-UN relationship, representation in the IMF as well as WTO jurisprudence involving the EU in 2015. The volume concludes with reviews of recent books in international economic law.
