During the Sui and Tang Dynasties, the two countries had close contacts and frequent cultural exchanges, such as Jian Zhen's eastward crossing, and Japanese sending envoys to China in the Tang Dynasty. During the Ming Dynasty, the southeast coast of China was invaded by Japanese pirates. After Meiji Restoration in the late Qing Dynasty, Japan stepped up its aggression against China and launched the Sino-Japanese War of 1894-1895. After that, it constantly invaded China's territory and sovereignty, reaching its peak in War of Resistance against Japanese Aggression. After the founding of New China, the two countries were in a state of hostility for a long time. It was not until 1972 that Japanese Prime Minister tanaka kakuei visited China that the two countries formally established diplomatic relations. Since then, China and China have maintained their cooperative and friendly relations for 40 years for the needs of their domestic economic development. However, from September 12 to June 14, the Japanese government unilaterally nationalized China's inherent territory, which undermined the understanding and tacit understanding reached by the older generation of leaders of China and Japan and plunged Sino-Japanese relations into conflict and hostility again.

Historically, as long as China is strong, Japanese will learn from China. As long as China's strength declines and Japanese strength rises, it will try to plunder China and invade China, in which the full-scale aggression against China flourished during World War II. However, judging from the current form of Diaoyu Island, China is also in a relatively good period of development and prosperity, and Japan should not fight China at this time, because it will never win if it fights now. There are two main reasons why Japan dares to challenge China now. First, it saw the U.S. strategy moving eastward, thinking that it could use the power of the United States to balance China and gain its own strategic interests. Second, because our own strength is not strong enough, insisting on development is the last word. Only when we are really strong, Japan will naturally be honest. ..
