Asia Pacific 1902: Anglo-Japanese Alliance
During the Boxer Rebellion, Russia had occupied Manchuria. Suspicious of Russian intentions in the region and wary of its alliance with France, Britain and Japan signed a defensive agreement, promising to come to each other's aid should either of them get involved in a war with two or more powers.
Treaty ports - the small unlabelled circles on the map - were towns opened to foreign trade by unequal treaties in China, Japan, and Korea. Foreigners operating within treaty ports enjoyed extraterritoriality, being subject to their home country’s laws. Unlike concessions such as Hong Kong, these territories were not directly leased by the foreign powers and did not have sizable foreign garrisons.
Only treaty ports that were opened by treaty and used are shown on the maps. Treaty ports are also not generally shown in places which are already covered by concessions or under occupation. Treaty ports are not shown after the 1911 Chinese Revolution, although they continued on into the 1940s.
By the terms of the Treaty of Tientsin (1858), foreign vessels including warships had the right to free navigation on the Yangtze River. In practical terms, this right extended only as far as Yichang until 1900, when advances in steam navigation allowed access as far inland as Chongqing.
