Commonwealth free trade is the process or proposal of removing barriers of trade between member states of the Commonwealth of Nations. The preferential trade regime within the British Empire continued in some form amongst Commonwealth nations under the Imperial Preference system, until that system was dismantled after World War II due to changes in geopolitics and the pattern of global trade, and the United Kingdom's entry into the European Economic Community. The idea of promoting renewed inter-Commonwealth trade emerged in the late 20th century as a response to the evolution of the global economy. At one extreme, proposals have been raised for the creation of a multilateral free trade area comprising all member states of the Commonwealth of Nations.
