This is the first chapter that I have written for my memoirs. It has just been published in the Chinese (Taiwan) Yearbook of International Law and Affairs (vol. 33). It tries to answer the question I am most often asked: why and how did you decide to take up what was in 1960 an extremely arcane, indeed an unknown, subject. It also necessarily seeks to provide a picture of the state of Sino-American relations at that time and of American attitudes toward and understanding of what was still called “Red China”. I will eventually give an account of my roots and development prior to 1960 but it seemed most appropriate to start with the decision to study China.
