Abstract: By quoting archives, this article examines China’s program for training Albanian interns during the Cold War as a case of foreign economic and technical assistance and interprets the public diplomatic behavior intended to “establish socialist brotherhood” among Albanian interns based on the political alliance between China and Albania. The historical facts about China’s training Albanian interns show that, the basic characteristic of public diplomatic behavior under the revolutionary diplomatic route lies in its pursuit of a single ideological commonality as the premise and goal, but such public diplomatic behavior could hardly promote the development of relations between countries in a substantial way on account of its excessive pursuit of ideological interests.
