三国干渉
Russia had the most to gain out of the Triple Intervention. In the preceding years, Russia had been slowly increasing its influence in the Far East. The construction of the Trans-Siberian Railway and the acquisition of a warm-water port would enable Russia to consolidate its presence in the region and further expand into Asia and the Pacific. Russia had not expected that Japan would be victorious against China. Port Arthur falling into Japanese hands would undermine its own desperate need for a warm-water port in the East.
