Papua New Guinea's foreign policy reflects close ties with Australia and other traditional allies and cooperative relations with neighboring countries. Its views on international political and economic issues are generally moderate.
Relations with Australia were strained in 2006 when Prime Minister Sir Michael Somare was accused of having facilitated Julian Moti's escape to the Solomon Islands.[57] Moti was wanted in Australia for serious alleged child sex offences. In retaliation, the Australian government banned Somare from entering Australia; all talks between Canberra and Port Moresby were suspended. In September 2007, relations began to thaw,[58] and in December 2007, the new Australian Prime Minister, Kevin Rudd, met Sir Michael in Bali. Rudd announced what appears to be a normalisation of relations: "This relationship has been through a very difficult period in recent times. There has in effect been a freeze on ministerial contact between the two governments. I do not believe that's an appropriate way for the future."[59]
Australia has a High Commission in Port Moresby and a consulate-general in Lae.[60]
The Independent State of Papua New Guinea and the People's Republic of China (PRC) established official diplomatic relations in 1976, soon after Papua New Guinea became independent. The two countries currently maintain diplomatic, economic and, to a lesser degree, military relations. Relations are cordial; China is a significant provider of both investments and development aid to Papua New Guinea.
In the late 2000s, Papua New Guinea began to strengthen its relations with Cuba. Cuba provides medical aid to the country.[64] In September 2008, a PNG government representative attended the first Cuba-Pacific Islands ministerial meeting in Havana, aimed at "strengthening cooperation" between Cuba and Pacific Island countries, notably in coping with the effects of climate change.[65]
Official diplomatic relations were established in 1976. Papua New Guinea is a member of the United Nations' Special Committee on Decolonization. The French government has noted what it calls Port Moresby's "moderate" attitude on the issue of the decolonisation of New Caledonia - which, like Papua New Guinea, is located in Melanesia.[67] The French National Assembly maintains a Friendship Group with Papua New Guinea.
Diplomatic relations between Japan and Papua New Guinea were established on 16 September 1975, the date Papua-New Guinea became independent. Japan maintains an embassy at Port Moresby. Papua-New Guinea is currently the largest recipient of Japanese foreign aid in the Pacific. Ministerial level visits are frequent between the two countries.[71] Reciprocally, Papua New Guinea has an embassy in Tokyo.
In March 2009, The Philippines and Papua New Guinea entered into a Memorandum of Understanding (MoU) that would enhance the cooperation between the two countries on the development of fisheries. The MoU will facilitate technology transfer in aquaculture development, promotion of shipping ventures, investments, technical training, joint research, and "strategic complementation" of each country's plans in the "Coral Triangle" – or the waters between the Philippines, Indonesia, and the Pacific Islands.[75] In the same year, Papua New Guinea asked the Philippines for help in its pursuit of membership to ASEAN.[76][77]
Papua New Guinea and the United Kingdom share King Charles III as their head of state. They have had relations since 1975 when Papua New Guinea gained independence from Australia.
Papua New Guinea has a High Commission in London.[83]
United Kingdom has a High Commission in Port Moresby.[84]
The U.S. and Papua New Guinea are signatories to the U.S.-Pacific Islands Multilateral Tuna Fisheries Treaty, under which the U.S. grants $63 million per year to Pacific Island parties and the latter provide access for U.S. fishing vessels. The U.S. also supports Papua New Guinea's efforts to protect biodiversity; the International Coral Reef Initiative is aimed at protecting reefs in tropical nations such as Papua New Guinea.
