The Japanese army conquer German Tsingtao 1914
- Japan astutely joined Britain and France for WW1 and took over German Chinese possessions as soon as she could.
- In 1915 Japan presented China with the 21 Demands, taking even more power from China, and indirectly depriving China of her best leader Yuan Shikai.
- After WW1 Japan was not asked to return any Chinese land, despite China supporting the British and French in the war. This caused the May 4 riots in China 1919.
