The Qing Dynasty ceded Sakhalin Island to Russia. Why doesn't Japan agree?

This is mainly because Sakhalin Island is close to Japan. At that time, Japan was unable to confront Russia. So this will pose a great threat to Japan's territorial security. This is why Japan will not agree to cede Sakhalin Island to Russia. This is mainly because Japan did not experience the Meiji Restoration at that time, which made Japan's military strength and economic strength insufficient to fight against Russia. Russia, a country with very strong military strength, will pose a great threat to Japan's territorial waters and territory once it is close to Japan's territory.

At that time, it was a very humiliating history for the Qing Dynasty, because a series of unequal treaties were often signed, which made many territories in China occupied by foreigners. But Sakhalin Island was occupied by Russia in this situation. Sakhalin Island has not returned to China until now. So China at that time was a very gloomy and turbulent time. Under the corrupt rule of the Qing Dynasty, the people of China at that time were miserable, and even the people of China suffered great personal and property safety threats because of the long-term occupation of China territory by foreign invaders.

However, the geographical position of Sakhalin Island is very important, which not only poses a great military threat to neighboring countries, but also has a lot of energy resources around Sakhalin Island. Therefore, the status of Sakhalin Island is becoming more and more important, which makes Russia never give up Sakhalin Island. And now Russia has also strengthened the intensity of Russian immigration. It also puts a lot of pressure on Japan from Sakhalin Island. This is mainly because of the territorial dispute between Russia and Japan, which also makes the two countries have been arguing over some territorial issues.

So this is a very humiliating history for China, because it is to divide China's own territory into other countries. Therefore, we must study hard to build our own country, so that the scene of the Qing Dynasty signing a series of unequal treaties can no longer be seen by the people of China now.
