There has been a long-running dispute, primarily between Norway and Russia (and before it, the Soviet Union) over fishing rights in the region.[14][15] In 1977, Norway established a regulated fishery in a 200 nautical miles (370 km) zone around Svalbard (though it did not close the zone to foreign access).[14] Norway argues that the treaty's provisions of equal economic access apply only to the islands and their territorial waters (four nautical miles at the time) but not to the wider exclusive economic zone.
