1930 Imperial Conference was the seventh Imperial Conference bringing together the Prime Ministers of the dominions of the British Empire . It was held in London . The conference was notable for producing the Statute of Westminster , which established legislative equality for the self-governing Dominions of the British Empire with the United Kingdom , thereby marking the effective legislative independence of these countries , either immediately or upon ratification . Economic relations within the British Empire was also a key topic with proposals for a system of Imperial preference - empire-wide trade barriers against foreign ( i.e. non-empire ) goods . These proposals were further discussed at the British Empire Economic Conference in 1932
