The former head of United Nations observers in the Papua New Guinea province of Bougainville says the mission could serve as a model for a new type of peacekeeping.
The Norwegian, Tor Stenbock, has told a briefing at the UN headquarters in New York that the organisation has learnt quite a few lessons in Bougainville.
Mr Stenbock says the mission can be used as a model for the projects put forward by the UN's peacebuilding commission.
Mr Stenbock has been part of larger UN missions but he says his doesn't mean that smaller ones like Bougainville can't set an example.
"Small missions like this has the right to life. In effectiveness, it's manageable, and I do think that a political mission like this can be used elsewhere in the world."
Mr Stenbock says peacebuilding missions will have to adjust to local conditions.
