The arrival of United Nations Secretary-General Ant贸nio Guterres in Port Moresby on September 2 marked the first official visit by a UN chief to Papua New Guinea, a moment of historic significance.
Grand Chief Sir Bob Dadae warmly welcomed him, praising PNG's achievements in peacebuilding and democracy as the country nears its 50th Independence Anniversary.
Beneath this historic visit and the diplomatic celebration lay a deeper story 鈥 one that exposes the UN鈥檚 double face in Melanesia. On one side stands Bougainville, where dialogue and international support birthed a fragile but real peace. On the other side lies West Papua, where the same institution abandoned an entire people to silence, militarisation and slow extinction.
Bougainville: The long road to peace
The centrepiece of Guterres' visit was a peace and reconciliation ceremony with the Autonomous Province of Bougainville 鈥 a milestone reflecting decades of dialogue after a brutal civil war that claimed more than 20,000 lives.
In 2019, more than 98% of Bougainvilleans voted for independence in a referendum. While non-binding, this overwhelming result built on years of patient negotiation between the PNG government and the Autonomous Bougainville Government, supported by international mediators including Sir Jerry Mateparae, Aotearoa/New Zealand鈥檚 former Governor General.
The UN played a decisive role: funding local initiatives, guaranteeing transparent elections, supervising weapons disposal, and building the administrative capacity for Bougainville鈥檚 transition toward independence, now targeted for 2027. In Bougainville, the UN lived up to its creed. Dialogue replaced violence. Trust took root where hatred had burned. The voices of the people were honoured.
Bougainville stands as proof of what is possible when justice is not delayed.
West Papua: A nation betrayed
Across PNG's western border, West Papua tells a starkly different story. West Papua 鈥 once promised freedom 鈥 has been betrayed and condemned to silent death.
The betrayal began in 1969 with the so-called "Act of Free Choice". About 1000 men and women, handpicked by Indonesia, were forced under the gaze of armed soldiers to 鈥渃hoose鈥 integration with Indonesia. The UN, though present, closed its eyes. It blessed a fraud that mocked every principle of self-determination written in its own charter.
Since then, West Papua has endured militarised occupation, systematic human rights abuses, and widespread displacement and replacement of indigenous communities.
Calls for UN special rapporteurs and independent observers have gone unanswered for decades, while Jakarta tightly restricts international access to the territory. Unlike Bougainville, where international mediation created pathways to peace, West Papua remains trapped in cycles of violence and enforced silence.
The international community has not remained passive. Over 110 countries have now demanded that the UN High Commissioner for Human Rights be allowed to visit West Papua. This groundswell includes support from the Pacific Islands Forum, the Organisation of African, Caribbean and Pacific States, and the European Commission. Despite this unprecedented pressure, Indonesia continues to block access, directly defying international demands.
West Papuans remain grateful for Pacific solidarity, yet Jakarta's intransigence undermines the credibility of regional diplomacy itself, exposing how Indonesia holds the entire Pacific Islands Forum hostage to its domestic agenda.
The UN's original sin
To understand today's crisis, we must confront the UN's original failure. In the early 1960s, West Papua was formally listed in the UN decolonisation list as a non-self-governing territory with recognised rights to eventual independence. But the 1962 New York Agreement, negotiated between the Netherlands and Indonesia without any Papuan representation, tragically buried that status.
Under this arrangement, the UN handed administrative control to Indonesia in 1963, paving the way for Indonesian military occupation. The promise of genuine self-determination in 1969 became a carefully orchestrated deception. Instead of challenging this fraud, the UN legitimised an outcome born of coercion and fear.
For Papuans, this remains the moment of ultimate betrayal: when the very institution created to protect their rights instead sanctioned their subjugation.
Indonesia's shield strategy
Rather than adopting PNG's collaborative peace-building approach, Indonesia has systematically worked to shield West Papua from international scrutiny. At the 46th ASEAN Summit in May, Indonesian President Prabowo Subianto proposed full ASEAN membership for PNG. While framed as regional integration, this initiative serves Jakarta's strategic interests. Embedding PNG within ASEAN's principle of "non-interference" strengthens Indonesia's narrative that West Papua is purely a domestic matter, deflecting pressure for international oversight or a final UN-supervised resolution to restore West Papuans sovereignty
Two paths, one moral test
Bougainville and West Papua represent two fundamentally different approaches to indigenous struggles for self-determination. Bougainville proves that peaceful resolution is achievable when governments negotiate in good faith, international actors provide credible oversight, and local voices are genuinely heard and respected.
West Papua illustrates the devastating alternative: militarisation, systematic exclusion, and the denial of basic human dignity. Its continuing tragedy represents not failed peace-building, but deliberately unfinished decolonisation.
The UN's unfinished business
The UN cannot celebrate Bougainville's success while wilfully ignoring West Papua's suffering. Its catastrophic failure in 1969 created unresolved political and humanitarian consequences that continue to push West Papuans into the brink of extinction today.
The path to redemption requires concrete action: dispatching fact-finding missions to document the truth, deploying human rights monitors to protect Papuans, and creating conditions for peaceful, internationally credible resolution of this longstanding 鈥 neglected genocide.
Guterres' historic visit to PNG demonstrated the UN at its transformative best 鈥 helping convert Bougainville's devastating conflict into a viable path toward independence. But West Papua remains the organisation's most shameful unfinished business, a betrayal that corrodes UN credibility throughout the Pacific region.
The Secretary-General now faces a defining choice. If Bougainville is remembered as a triumph of international peace-building, West Papua risks being forever marked as the UN's greatest moral failure 鈥 unless decisive action is taken now to ensure West Papuans' survival.
History will ultimately judge whether this historic moment becomes a catalyst for long-overdue justice or merely another ceremonial gesture while Indigenous Papuans on the western side of PNG鈥檚 border face extinction.
