# Indonesia–Papua New Guinea relations

Indonesia–Papua New Guinea relations are foreign relations between Indonesia and Papua New Guinea.
Indonesia and Papua New Guinea share an 820-kilometre (510 mi) border that has raised tensions and ongoing diplomatic issues over many decades.
Indonesia is represented in Papua New Guinea with an embassy in Port Moresby and a consulate in Vanimo, while Papua New Guinea is represented in Indonesia with an embassy in Jakarta and a consulate-general in Jayapura. Both nations are members of APEC, Non-Aligned Movement and the United Nations.

## History

The two nations established diplomatic relations on 16 September 1975.
Dutch colonial and Indonesian government actions over the populations in western Papua region have caused an extensive and ongoing border issue which has a lengthy and enduring presence of refugees moving between Papua and Papua New Guinea.
Leo Suryadinata writes that after "a number of border conflicts, Indonesia eventually signed a border treaty with Papua New Guinea in 1979"; however, issues continued while Indonesia pursued Papuans well after this date, and still continue to harass various population groups in the highlands of Papua adjacent to the border with Papua New Guinea. The border is a straight line, drawn without considering the geological features, except for a slight indentation to the west at the Fly River, created in 1893 to allow for better British policing of the area.
Sean Dorney of the Australian Broadcasting Corporation in his book Papua New Guinea — people, Politics and History since 1975 has the quote from a statements by the Indonesian Embassy in Port Moresby in 1978 in relation to the pursuit of Papuan rebels:
   Indonesia wants PNG to grow strong and be a good neighbour. Therefore if there is a dream that we want to invade Papua New Guinea, we would do it now when Papua New Guinea is still weak, rather than to wait (for) Papua New Guinea to become strong

## Trade

Trade between the two countries amounted to US$ 256 million in 2018, with the trade balance being strongly favourable to Indonesia. A preferential trade agreement between the two countries have been considered. Vanilla is one commodity exported from PNG to Indonesia. The first Indonesia–Papua New Guinea Business Forum was held in 2023, attended by president Joko Widodo and PM James Marape.

## Refugees

Due to conflict adjacent to the border between the two countries, refugees have crossed the border regularly. The largest amount of refugees originated in 1984, with over 10,000 Papuans from the Indonesian side crossing the border.
The main issue of refugees is from conflict between Indonesian national security forces, and various groups of disaffected groups in West Papua seeking refuge in the Papua New Guinea territory.
The subsequent diplomatic issues that have arisen, usually is the refugee flows and border transgressions by Indonesian forces.
   Its (PNG) proximity and cultural ties to the Indonesian province of Papua means there is potential for a mass influx of West Papuan refugees. Given the continuing political instability and the security situation in Papua, regular revision of PNG's contingency plans and training of GoPNG officials is considered important.

## Treaty

Talks about the border moved to the signing, on 27 October 1986, of the Treaty of Mutual Respect, Cooperation, and Friendship
   The treaty was, in effect, a bilateral nonaggression pact in which the two sides agreed to "avoid, reduce and contain disputes or conflicts between their nations and settle any differences that may arise only by peaceful means".
