Jean Ho, FCIArb, is Assistant Professor of Law at the National University of Singapore, where she lectures and supervises on diverse aspects of international investment law. Prior to academia, Dr Ho practiced in investor-state dispute settlement. She is a Member of the Investment Treaty Forum of the British Institute of International and Comparative Law, and an Expert on the UNIDROIT Working Group on Land Agricultural Investment Contracts. Dr Ho is also a co-author of International Investment Law and Arbitration: Commentary, Awards and Other Materials (Cambridge, 2018).

'The author has written an extremely valuable monograph on a topic that surprisingly has received little attention. International investment contracts were once considered the main source of obligations and of consent to binding dispute settlement, yet academic attention has been focused on treaty breach. This text examines the contractual context and makes the link between international responsibility of states under investment contracts and the international law developed through arbitral awards. It is well written and is a superb source of information and explanation about this aspect of international investment law.'
