This book attempts to illustrate the whole picture of international investment rule of law between China and African countries and find the way forward through combining theory and practice. It is a book by a Chinese professor based on her long-term research experience in the international investment law field and her African field work in person. Its main feature is its well-balanced thinking on the structure of investment international rule of law. It should be the most comprehensive research on the international investment rule of law between China and African countries. With the increase of Chinese investment in Africa, various discussions and viewpoints on Chinese investment in Africa have become striking. The purpose of this book is to explore systematically the protection and sustainability of Chinese investment under the concept and framework of the international investment rule of law, so as to serve the sustainable development of Africa and China. For the purpose of this book, great importance is attached to the idea of the international rule of law, and the international investment law with the function of rule of law is adhered to. The conclusion of this book is that China should take proactive steps to protect Chinese investment in Africa and regulate Chinese overseas investors and their investments in addition to complying with the laws in the host states and thus make them conductive to African and Chinese sustainable development; however, the most significant issue is that China-Africa investment relations should be regulated by the evolving and specific international investment rule of law, and the China-Africa international investment rule of law should conform to normative in form, support common sustainable development in value, and reflect the social reality of China and Africa.  For both researchers and students, it is an approach to understand international investment rule of law from a perspective of China and Africa. For those who are interested in China and Africa, it is a useful reference book.
