三国干渉
The conditions imposed by Japan on China led to the Triple Intervention of Russia, France, and Germany, western powers all active in China, with established enclaves and ports, just six days after its signing. They demanded that Japan withdraw its claim on the Liaodong peninsula, concerned that Lüshun, then called Port Arthur by Westerners, would fall under Japanese control. Tsar Nicholas II of Russia (an ally of France) and his imperial advisors, including his cousin-advisor-friend-rival Kaiser Wilhelm II of Germany, had designs on Port Arthur, which could serve as Russia's long sought-after 'ice-free' port.
