US "Open Door" Policy Toward China & Japan in the 19th Century

In the late 19th century, the U.S. pursued the "Open Door Policy" toward China—and a parallel approach toward Japan—to secure equal commercial access and prevent exclusive spheres of influence.

China: The Classic Open Door (1899–1900)

• Context: After Sino-Japanese War (1894–95), powers (UK, France, Germany, Russia, Japan) carved out spheres of influence (leaseholds, railway rights, mining concessions).
• John Hay's Notes (1899, 1900): Sec. of State Hay circulated diplomatic notes urging:
  1. No interference with treaty ports/vested interests in spheres.
  2. Chinese tariff uniformity in all spheres.
  3. No discriminatory railroad/harbor charges.
• Goal: Preserve Chinese territorial integrity for U.S. trade access; prevent partition like Africa.

Japan: Treaty-Based Equality (1850s–1890s)

• 1853–54: Perry Expedition forces opening (Treaty of Kanagawa).
• 1858: Harris Treaty (Treaty of Amity and Commerce) — establishes most-favored-nation (MFN) status, extraterritoriality, low fixed tariffs.
• 1894: Revised Treaty (effective 1899) — Japan gains tariff autonomy, ends extraterritoriality; MFN ensures U.S. gets same terms as any other power.

Similarities

• Equal Opportunity: Both policies sought non-discriminatory market access for U.S. goods/capital.
• Anti-Hegemony: Opposed single-power dominance (Russia in Manchuria; any power in Japan).
• Legalistic Approach: Used treaties/notes to codify equality.
• Ideology: Framed as "free trade," "fair play," "international law"—advancing U.S. economic interests while opposing formal empire.

Differences

• China: Multilateral notes to other powers (China weak, not party).
• Japan: Bilateral treaties with Japan (Japan modernizing, negotiating as sovereign).

Both reflected the U.S. rise as a Pacific power seeking markets without colonies.
