The Pacific Islands Forum and the United Nations have issued a joint statement, agreeing to consider ways of working more closely together.
This follows the UN secretary general Ban Ki-moon's attendance of the Forum summit in Auckland.
The two sides say they agree on the importance of sustainable economic growth in achieving the Millennium Development Goals.
They say they will aim to achieve this by using the Barbados Programme of Action, the Mauritius Strategy, the Istanbul Programme of Action and the Pacific Plan.
They also noted the value of their co-operation in dealing with conflicts, citing the Papua New Guinea island of Bougainville and Solomons Islands.
