Territory Former Claimants Dispute Started Dispute Settled Notes
Sakhalin Island  Russian Empire
 Empire of Japan
1845 1875 Japan unilaterally proclaimed sovereignty over the whole island in 1845, but its claims were ignored by the Russian Empire. The 1855 Treaty of Shimoda acknowledged that both Russia and Japan had joint rights of occupation to Sakhalin, without setting a definite territorial demarcation. As the island became settled in the 1860s and 1870s, this ambiguity led to increasing friction between settlers. Attempts by the Tokugawa shogunate to purchase the entire island from the Russian Empire failed, and the new Meiji government was unable to negotiate a partition of the island into separate territories.
In the Treaty of Saint Petersburg (1875), Japan agreed to give up its claims on Sakhalin in exchange for undisputed ownership of the Kuril Islands.

The dispute had been going on between the Russian and British Empires since 1821, and was inherited by the United States as a consequence of the Alaska Purchase in 1867. It was resolved by arbitration in 1903 with a delegation that included 3 Americans, 2 Canadians, and 1 British delegate that became the swing vote. By a 4 to 2 vote, the final resolution favored the American position. Canada did not get an outlet from the Yukon gold fields to the sea. The disappointment and anger in Canada was directed less at the United States, and more at the British government for betraying Canadian interests in pursuit of a friendly relationship between Britain and the United States.
