Who can tell us why Sino-Japanese relations felt better in the 1970s and 1980s than they do now?

Quite simply, there are no eternal friends, but there are eternal interests.

1959 Sino-Soviet relations deteriorated, 1969 Sino-Soviet armed conflict even occurred in Zhenbao Island. In order to fight against the Soviet Union, China joined the American camp. 1972 After Nixon's visit to China, Sino-US relations gradually normalized, and Japan followed in the footsteps of the United States. In the same year, Premier tanaka kakuei's visit to China was realized, which initiated the normalization of Sino-Japanese relations.

At that time, China was worried about the massive invasion of the Soviet Union from the three northern regions (Northeast China, Xinjiang, Mongolia), Japan was also worried about the massive invasion of the Soviet Union from Hokkaido, and Western Europe was worried about the massive influx of steel from the Eastern European plain. The same concern made China, Japan and Europe rapidly approach under the leadership of the United States and enter the "honeymoon period".

In particular, the Sino-Vietnamese War around 1979 made the United States, Japan and Europe think that China has completely become its own kind, so the relations between China, the United States, China and Japan and China and Europe were very good throughout the 1970s and 1980s.

However, in the early 1990s, the Soviet Union disintegrated, and then Russia fell into a quagmire. Strong pressure and the need to confront the Soviet Union no longer exist. The contradiction between China and the United States has intensified rapidly, and the corresponding China and Japan have also gone further and further.

Therefore, Sino-Japanese relations are the epitome of Sino-US relations, and Sino-US relations are the embodiment of mutual interests. Whether it is cooperation or confrontation, in the final analysis, it is for the benefit.
