The Papua New Guinea Government has achieved a significant milestone by officially submitting its geographical coordinates under the United Nations Convention on the Law of the Sea (UNCLOS). This submission serves to reaffirm PNG’s territorial boundaries and maritime zones, thereby securing its economic and strategic interests, especially as the nation marks its 50th anniversary of independence.
Minister for Foreign Affairs Justin Tkatchenko celebrated this crucial development, noting that the formal submission process reflects over two decades of persistent efforts starting with initial submissions in 2002, and culminating in the latest update in 2024. This comprehensive submission includes essential data on PNG’s baselines and the outer limits of its exclusive economic zone (EEZ). It has been bolstered by support from international partners, including the South Pacific Community (SPC), which provided technical expertise through projects designed to clearly define PNG’s maritime boundaries on the global stage.
Tkatchenko acknowledged the instrumental financial and logistical contributions from international donors such as the Australian Department of Foreign Affairs and Trade, the United Kingdom, and the European Union, which played pivotal roles in overcoming both technical and legal challenges associated with maritime boundary assertions.
The importance of this achievement extends further against the backdrop of rising global concerns regarding climate change. As sea levels threaten coastlines and maritime boundaries, PNG’s commitment to maintaining its sovereignty is underscored. Clearly defined maritime boundaries not only fortify PNG’s claims but also enhance fisheries enforcement, environmental conservation, and the overall stability of regional security.
Minister Tkatchenko reaffirmed PNG’s dedication to uphold the 2015 Pacific Islands Forum Leaders’ Declaration, which advocates for the permanence of maritime base points despite physical changes brought by climate-induced sea-level rise. This commitment is vital for preserving PNG’s maritime zones and strengthening national security against threats such as illegal fishing and transnational crime.
This recent submission highlights the nation’s proactive stance in safeguarding its maritime interests amidst escalating geopolitical dynamics, ensuring that PNG remains a steadfast presence in both regional and international affairs.
In summary, PNG’s submission marks a significant step towards securing its maritime rights, reflecting a firm resolve to protect its sovereignty and affirm its position in a changing geopolitical landscape. As countries face environmental and security challenges, PNG’s actions serve as a positive example of how nations can proactively safeguard their interests while also contributing to regional stability and sustainability.
