The book holds importance now when countries are trying to update their bilateral and multilateral International Investment Agreements (IIAs) to address global complexities in international investment. For this reason, the book is useful for people learning the subject and provides reliable support for those working in the field.

The authors have incorporated various aspects of international investment law (IIL) into a format that combines expert's theories with useful guidance. The initial part of the text details how investment law started with regulation based on British colonies, became more widespread after World War II, and now faces challenges because of criticism against ISDS. As a result, the book gives readers a chance to how international investment rules are formed, and not only how they operate.

The book discusses well-known rulings, which reveal that how disputes are handled can change with time and the tribunal. It is also worthy that the book addresses the conflicts between supporting investors and maintaining the freedom of host states over regulations.

The addition of information about the reform of ISDS, third-party funding, SDGs, and new treaty practices in India makes the book informed by current matters. It motivates one to carefully consider the rules rather than just follow them as they are, which is crucial in a subject that changes fast.

The book provides a valuable contribution towards literature in the field of international economic law. It promotes legal research, strengthen abilities in the legal sector, and develop a more even and open investment framework for importing and exporting countries.
