Burnham is a significant place for the talks, having being previously used to negotiate a ceasefire during the civil war fought from 1988 to 1998 in the region that paved the way to the independence referendum.
The President of Bougainville, Ishmael Toroama, said that he wants the talks to be productive. "The people of Bougainville are hoping for finality, they have high expectations that Burnham will finally provide the roadmap to Bougainville’s independence," he said.
An agreed document is anticipated to be made by the end of the week, indicating possible progress for the region's independence.
Prime Minister of Papua New Guinea, James Marape, is not present for the talks. Manasseh Makiba, Minister for Bougainville Affairs, is representing the country in his absence.
The talks are expected to continue until Friday.
