Zone économique exclusive
Australia and Taiwan used other documents that were not technically legally binding to develop their unofficial relationship. These included Memorandums of Understanding, which under Australia law are not documents to which the Vienna Convention on the Law of Treaties applies. Instead, such agreements encourage relations between states on a 'moral and political basis.' Arrangements were made on a variety of topics such as access by Taiwanese fishing vessels to Australia's Exclusive economic zone, which were established in 1979 and 1986.
