The Four Principles that Formed the Basis of Friendly Relations between Japan and China: The China Policy of the Nakasone Yasuhiro Government

This article examines Nakasone Yasuhiro’s policy toward China as a politician, including his remarks in the Diet before appointment as prime minister as well as exchanges with Chinese leaders during his prime ministership. Nakasone raised Japan-China relations to a level called a “honeymoon” in the 1980s, at which time the four principles of Japan-China relations were shared and there was the prospect of continued friendly relations into the 21st century. Behind the emergence of this era was not only Japan’s support for China’s economic development through ODA, but also the closeness of the stances that both Japan and China held toward the Cambodia and Korean Peninsula issues at the end of the Cold War. This may have been because there was the possibility for both parties to share information and mutually support each other. Nakasone actively talked not only with Hu Yaobang but also leaders such as Deng Xiaoping and Zhao Ziyang. However, as Nakasone’s partner Hu Yaobang was dismissed and the Cold War approached its end, the “honeymoon” between Japan and China came to an end, and the four principles by Nakasone and Hu gradually became just one frame of history.
