These treaties are called the Treaty of Nebuchadnezzar and the treaty of shimonoseki.
The Treaty of Nebuchadnezzar Chu was then known as the Treaty of Nebuchadnezzar Chu.
Treaty of shimonoseki was originally named Shimonoseki New Testament, while Japan called it treaty of shimonoseki or Nissin Peace Treaty.
Judging from the Japanese appellation, it was really not called China at that time.
Now, in order to explain the two sides of the treaty, the correct writing is the Sino-Russian Treaty of Nebuchadnezzar Chu and the Sino-Japanese treaty of shimonoseki.
At that time, China was not a national concept, but more a concept of culture, nationality and region.
