The Taiwan Relations Act (TRA) of 1979 was adopted following President Carter's recognition of the People's Republic of China and de-recognition of Taiwan. Congress, The Presidency and the Taiwan Relations Act is a study of the adversary relationship that exists between the President and Congress, viewed both in broad historical perspective as well as in relation to the TRA as a specific case in point illustrating the interbranch tug-of-war in the foreign policy process. The contributors to this volume explore the background of the interbranch division of labor and examine the enactment and implementation of the TRA both as a putative example of an assertive Congress and as a possible focal point of tensions between the two branches.
