Japan's victory in the First Sino-Japanese War greatly expanded its influence in Korean domestic politics, intensifying rivalry with Russia over control of the Korean peninsula. Both empires sought to assert political and economic dominance, creating mounting tensions that required diplomatic resolution to avoid direct confrontation.
Signed in Tokyo on 25 April 1898, the Nishi-Rosen Agreement committed both Japan and Russia to non-interference in Korean domestic politics and required mutual prior consent before dispatching military or financial advisors to Korea. Russia explicitly pledged not to obstruct Japanese commercial investment in Korea.
By acknowledging Korea as falling within Japan's economic sphere of influence while Japan implicitly recognized Russia's lease of the Liaodong Peninsula, the agreement produced a fragile balance of power. This compromise proved short-lived, as unresolved rivalry over Manchuria and Korea ultimately contributed to the outbreak of the Russo-Japanese War in 1904.
Political Outcome
Both powers agreed to non-interference in Korean affairs and mutual consultation; Russia recognized Japanese economic primacy in Korea while Japan acknowledged Russia's Liaodong Peninsula lease.
