This sixth volume (2015) of the European Yearbook of International Economic Law puts a particular emphasis on non-tariff barriers (NTBs) to trade and the world trade order. With the steady reduction of tariff rates since the GATT 47 came into force, focus in recent years has been on the vast and complex landscape of non-tariff barriers to trade. States as well as scholars seemingly struggle with the multitude of measures pooled under this expression as there is no single, acknowledged definition of the term, and its relation to the term “non-tariff measures” remains equally blurred. Particularly in practice and on a multilateral level, there appears to be some awkwardness when it comes to coping with NTBs since multilateral trade rules seem to be in conflict with national regulatory autonomy in the pursuit of policy objectives. In part one, this volume sheds light on the problems of non-tariff barriers to trade that arise in various fields. Part two focuses on regional integration with an emphasis on relations between East Asia and the European Union. In this regard, the authors outline the trade and investment relations between the European Union and East Asia, including Japan, Korea and Singapore. Part three offers an overview of recent institutional developments in WIPO, ICSID, WTO and WTO jurisprudence. Part four includes book reviews of recent works in the field of international economic law, and part five introduces a new section on publications in the field of international economic law that were released in 2013 and 2014.

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.

Volume 7 of the EYIEL focusses on critical perspectives of international economic law. Recent protests against free trade agreements such as the Transatlantic Trade and Investment Partnership (TTIP) remind us that international economic law has always been a politically and legally contested field. This volume collects critical contributions on trade, investment, financial and other subfields of international economic law from scholars who have shaped this debate for many years. The critical contributions to this volume are challenged and sometimes rejected by commentators who have been invited to be “critical with the critics”. The result is a unique collection of critical essays accompanied by alternative and competing views on some of the most fundamental topics of international economic law. In its section on regional developments, EYIEL 7 addresses recent megaregional and plurilateral trade and investment agreements and negotiations. Short insights on various aspects of the Transpacific Partnership (TPP) and its sister TTIP are complemented with comments on other developments, including the African Tripartite FTA und the negotiations on a plurilateral Trade in Services Agreement (TiSA). Further sections address recent WTO and investment case law as well as recent developments concerning the IMF, UNCTAD and the WCO. The volume closes with reviews of recent books in international economic law.

Volume 10 of the EYIEL focusses on the relationship between transnational labour law and international economic law on the occasion of the 100th anniversary of the International Labour Organisation (ILO). As one of the oldest UN Agencies, the ILO has achieved considerable progress with respect to labour rights and conditions. The contributions to EYIEL Volume 10 assess these achievements in light of current and future challenges. The ILO’s core instruments and legal documents are analysed and similarly the impact labour standards have on trade and investment agreements. In its regional section, EYIEL 10 addresses recent developments in the US and the EU, including the US’ trade policy strategy towards China as well as the reform of the NAFTA. In its part on institutions, EYIEL 10 focusses inter alia on the role of the rule of law in relation to current practices of the International Monetary Fund and of the WTO’s Appellate Body as an international court. Furthermore, it provides an overview of current cases before the WTO. Finally, the volume entails a section with review essays on recently published books in the field of international economic law and international investment law.

Part one of Volume 4 (2013) of the European Yearbook of International Economic Law offers a special focus on recent developments in international competition policy and law. International competition law has only begun to emerge as a distinct subfield of international economic law in recent years, even though international agreements on competition co-operation date back to the 1970s. Competition law became a prominent subject of political and academic debates in the late 1990s when competition and trade were discussed as one of the Singapore issues in the WTO. Today, international competition law is a complex and multi-layered system of rules and principles encompassing not only the external application of domestic competition law and traditional bilateral co-operation agreements, but also competition provisions in regional trade agreements and non-binding guidelines and standards. Furthermore, the relevance of competition law for developing countries and the relationship between competition law and public services are the subject of heated debates. The contributions to this volume reflect the growing diversity of the issues and elements of international competition law. Part two presents analytical reports on the developments of the regional integration processes in North America, Central Africa and Southeast Asia as well as on the treaty practice of the European Union. Part three covers the legal and political developments in major international organizations that deal with international economic law, namely the IMF, WCO, WTO, WIPO, ICSID and UNCTAD. Lastly, part four offers book reviews of recent works in the field of international economic law.

Volume 11 of the EYIEL focuses on rights and obligations of business entities under international economic law. It deals with the responsibilities of business entities as well as their special status in various subfields of international law, including human rights, corruption, competition law, international investment law, civil liability and international security law. The contributions to this volume thus highlight the significance of international law for the regulation of business entities. In addition, EYIEL 11 addresses recent challenges, developments as well as events in European and international economic law such as the 2019 elections to the European Parliament, Brexit and the EU-Mercosur Free Trade Agreement. A series of essays reviewing new books on international trade and investment law completes the volume.

Climate change is the defining challenge of our time. While political leadership and scientific expertise are key, law has a major role to play in fashioning responses. Volume 13 of the EYIEL assesses central aspects of the legal regimes governing "Climate Change and Liability". Covering traditional trade and investment topics as well EU instruments regulating private actors, contributions reflect the diverse links between international economic law and climate change. Through a mix of foundational inquiries and coverage of current issues (such as climate change litigation), the volume offers a rich and nuanced account of international economic law in an era of "Climate Change and Liability".
