The EU’s interest in and engagement with North East Asia has grown massively over the last three decades, the shaping and implementation of its policy influenced heavily by the UK and its historical links with East Asia. Brexit therefore raises questions about the future of this engagement and comes against a background of wider threats to the liberal world order, especially rising tensions between the USA and China. Worried that they may be forced to choose sides in their hitherto carefully managed relationships with the two, China’s neighbours are therefore watching with interest to see how the EU and the UK respond and manage their future relations with the region. This book goes beyond the traditional trade links to consider diplomatic and security perspectives, as well as wider issues such as the possible impact on educational and research links. It will be of interest to diplomats, scholars, and economists.
