North Korea is the land that they have wanted to take for generations. This mentality can be traced back to the Tang Dynasty. However, this was achieved after defeating Cixi and Russia.

Before the Russo-Japanese War, Britain and Japan reached an alliance, and Britain hoped that Japan would create some trouble for Russia. During the Russo-Japanese War, the Baltic Fleet made a long detour, because Britain did not allow Russians to stay in its own territory.

However, during the Russo-Japanese War negotiations, the Japanese made a "seven-doctor plan", in which seven doctors studying in Europe and America wrote a Russian compensation plan. The plan was insatiable, and the Russian czar slapped the table, but Russia just refused and prepared to mobilize troops to fight again.

However, Japan has run out of ammunition and food, so it can't fight any more, so it agreed to a treaty that can monopolize North Korea without Russian compensation. However, as soon as this treaty was returned to China, people in China generally refused to recognize it. They thought that ghost animals in Britain and the United States (where the word ghost animals came from) bullied the Japanese, and Japan killed more than 200,000 soldiers in vain, so they vandalized and looted foreign churches and embassies.

The British are very angry about this and think that without their own help, how can Japan win this war? How can we occupy North Korea? So from then on, Britain's attitude towards Japan became cold, which also caused some troubles for Japan to occupy Korea.
