ポストBrexitのEU世界戦略

：対外関係の再構築と加盟国間関係のゆらぎ

抄録

　The EU-UK Withdrawal Agreement entered into force on 1 February 2020 （at 11pm on 31 January, BST）, and the EU-UK Trade and Cooperation Agreement applied provisionally as of 1 January 2021 and came into force on 1 May 2021. After Brexit, even after the referendum on 23 June 2016, the EU was searching for a new global strategy: the EU has reconfigured its external relations; and the internal political dynamism has also been reconfigured among its twenty-seven member states.

　The UK has been one of the most powerful among EU member states: economically the second largest and militarily the very strongest, if we observe their power resources through the figures of GDP and military expenditures as of 2016. Looking back to the 1970s, as the aggregate economic power resources of its member states increased with the UK accession, the EC became an international actor, often called as a civilian power. After the Cold War, the EU even envisioned its security strategy: ESS in 2003 and a Global Strategy in 2016. On the other side, the UK has often been called as an awkward partner, which stopped or slowed down the EU's integration process.

　With Brexit, the EU should need to change its global strategy for foreign and security policy and for economic and monetary policy. Brexit should also change the internal politics among remaining EU member states as a Franco-German leadership would no more be challenged by the awkward partner. The future relationship between the EU and the UK was formulated on paper, but we have yet to observe its real nature. This symposium was successful in starting our academic debates with five brilliant papers by Masahide Kobayashi （on EU security and defence policy）, Sara Konoe （on politics of financial integration）, Ken Takeda （on intergovernmental politics among EU member states）, Yoko Iwama （on German leadership） and Daisuke Ikemoto （on UK-EU relations）. Yoichi Usui was instrumental in planning this symposium.
