AbstractIndonesia had long struggled to attain recognition by international law of its special geographical configuration, starting as early as 1958 at the Geneva Conference, until recognition of the archipelagic regime was embodied in Part IV of the LOS Convention. Now, with the legitimacy of archipelago status, Indonesia has enacted a new law on the Indonesian Territorial Waters in 1996, whereby the new straight archipelagic baselines using principles embodied in the LOS Convention can replace the old provision of straight baselines from point to point. This paper relates the leading role Indonesia has played in settling boundary disputes, and also gives an account of the ocean industries that have developed within the various regions of the archipelago. In contrast with its strong position on delimitation issues, Indonesia seems to have taken a somewhat more conservative approach to the development of its ocean industries.
