Seven Pacific nations have signed agreements on their maritime boundaries.
The signings took place as part of this week's Pacific Island Forum leaders' meeting being held in Rarotonga.
The region has approximately 48 shared boundaries where neighbouring jurisdictions overlap and of these only 21 are currently subject to treaty.
The agreements will bring legal clarity to the boundaries between several overlapping jurisdictions of neighbouring Pacific island countries.
The 7 treaties were signed by the leaders of the Cook Islands, Niue, Kiribati, Tokelau, Tuvalu, Nauru and the Marshall Islands.
