I just published a co-authored introduction to a set Japanese documents on the visit made by Prime Minister Nakasone Yasuhiro to China in March 1984 with Sergey Radchenko, now a Reader in International Relations at Aberystwyth University, and Yutaka Kanda, Associate Professor at Niigata University, Japan.
The documents and introduction were released by the Cold War International History Project (CWIHP) to coincide with the thirtieth anniversary of the visit.
While in China, Nakasone held three sets of conversations with Deng Xiaoping, Hu Yaobang, and Zhao Ziyang. The Japanese Foreign Minister, Abe Shintaro, also held talks with the Chinese Foreign Minister, Wu Xueqian.
As we describe in the introduction, this summit represented the peak of postwar Sino-Japanese relations, a time when the two countries were cooperating and exchanging information on a wide-range of bilateral and international issues.
