It gives me great pleasure to write a foreword to :\1r. Sen's excellent book, and for two reasons in particular. In the first place, in producing it, Mr. Sen has done something vvhich I have long felt needed to be done, and which I at one time had am bitions to do myself. \Vhen, over thirty years ago, and after some years of practice at the Bar, I first entered the legal side of the British Foreign Service, I had not been working for long in the Foreign Office before I conceived the idea of writing - or at any rate compiling - a book to which (in my own mind) I gave the title of "A ~fanual of Foreign Office Law. " This work, had I ever produced it in the form in which I visualised it, could probably not have been published con sistently with the requirements of official discretion. But this did not worry me as I was only contemplating something for private circulation within the Service and in Government circles. :Mr. Sen's aim has been broader and more public-spirited than mine was; but its basis is essentially the same.

A broad-ranging and ambitious study of the changing relationships between countries and their nationals abroad, and the impact that mass migration played in shaping modern international law and politics.

The 1961 Vienna Convention on Diplomatic Relations has for over 50 years been central to diplomacy and applied to all forms of relations among sovereign States. Participation is almost universal. The rules giving special protection to ambassadors are the oldest established in international law and the Convention is respected almost everywhere. But understanding it as a living instrument requires knowledge of its background in customary international law, of the negotiating history which clarifies many of its terms and the subsequent practice of states and decisions of national courts which have resolved other ambiguities. Diplomatic Law provides this in-depth Commentary. The book is an essential guide to changing methods of modern diplomacy and shows how challenges to its regime of special protection for embassies and diplomats have been met and resolved. It is used by ministries of foreign affairs and cited by domestic courts world-wide. The book analyzes the reasons for the widespread observance of the Convention rules and why in the special case of communications - where there is flagrant violation of their special status - these reasons do not apply. It describes how abuse has been controlled and how the immunities in the Convention have survived onslaught by those claiming that they should give way to conflicting entitlements to access to justice and the desire to punish violators of human rights. It describes how the duty of diplomats not to interfere in the internal affairs of the host State is being narrowed in the face of the communal international responsibility to monitor and uphold human rights.

This book offers a first overarching look at the relationship between states and their citizens abroad, approached through the concept 'Duty of Care'. How can society best be protected, when increasing numbers of citizens are found outside the borders of the state? What are the limits to care – in theory as well as in practical policy? With over 1.2 billion tourists crossing borders every day and more than 230 million expatriates, questions over the sort of duty states have for citizens abroad are politically pressing. Contributors explore both theoretical topics and empirical case studies, examining issues such as as how to care for citizens who become embroiled in political or humanitarian crises while travelling, and exploring what rights and duties states should acknowledge toward nationals who have opted to take up arms for terrorist organizations. This work will be of great interest to scholars in a wide range of academic fields including international relations, international security, peacebuilding, ethics and migration.

Beyond Human Rights, previously published in German and now available in English, is a historical and doctrinal study about the legal status of individuals in international law.

This third and last open access volume in the series takes the perspective of non-EU countries on immigrant social protection. By focusing on 12 of the largest sending countries to the EU, the book tackles the issue of the multiple areas of sending state intervention towards migrant populations. Two “mirroring” chapters are dedicated to each of the 12 non-EU states analysed (Argentina, China, Ecuador, India, Lebanon, Morocco, Russia, Senegal, Serbia, Switzerland, Tunisia, Turkey). One chapter focuses on access to social benefits across five core policy areas (health care, unemployment, old-age pensions, family benefits, guaranteed minimum resources) by discussing the social protection policies that non-EU countries offer to national residents, non-national residents, and non-resident nationals. The second chapter examines the role of key actors (consulates, diaspora institutions and home country ministries and agencies) through which non-EU sending countries respond to the needs of nationals abroad. The volume additionally includes two chapters focusing on the peculiar case of the United Kingdom after the Brexit referendum. Overall, this volume contributes to ongoing debates on migration and the welfare state in Europe by showing how non-EU sending states continue to play a role in third country nationals’ ability to deal with social risks. As such this book is a valuable read to researchers, policy makers, government employees and NGO’s.
