Let's Put the Future Behind Us
Comprised of most of the west coast of the former United States of America, Taiwan, Indonesia, Australia, New Zealand and the Pacific islands, the Pacific Commonwealth is a confederacy of nations based around the Pacific Rim.
Partially derived from Australian influence in Polynesia, Melanesia, Micronesia, the Pacific Commonwealth as it exists began with the secession of the western US states from the USA in 2173, prompting the creation of a jurisdictional panel known as the Pacific Summit. Although the constituent nations-states are self-governing, the Summit guarantees freedom of trade and movement between all constituent member states, except in exceptional circumstances.
Hong Kong-Macau was originally a member of the Pacific Commonwealth, but itself seceded in 2249. Unhappy with the Summit imposition of trade tariffs between the states of the Pacific Commonwealth and the rest of the globe, Hong Kong-Macau left the Commonwealth in order to be more competitive with non-Commonwealth states such as Japan and the Boston-Atlanta Metropolitan Axis.
