PNG Approves Defense Pact with Australia to Counter China's Pacific Influence
October 2, 2025
Papua New Guinea's Cabinet has approved a bilateral defense treaty with Australia, aiming to strengthen regional security and counter China's growing influence in the Pacific.
The treaty, modeled after Australia's ANZUS Treaty with the US and New Zealand, commits both nations to mutual assistance in the event of a 'common danger' and enhances military cooperation.
The agreement includes joint military training, improved technical interoperability, and cooperation on cybersecurity, reflecting a deepening strategic partnership.
While the cabinet approved the treaty with an absolute majority, official confirmation from the government has not been publicly provided.
The signing of the treaty was delayed from an initial scheduled date in September, but leaders issued a joint statement reaffirming its core principles.
Prime Minister James Marape announced that this is Papua New Guinea's first mutual defense pact of this nature, emphasizing its significance.
Australian Defence Minister Richard Marles expressed confidence that the treaty would be signed soon, indicating ongoing progress.
The move comes amid regional geopolitical shifts, with several Pacific nations shifting allegiance from Taiwan to China since 2019, highlighting China's growing influence.
China's embassy criticized the treaty, warning it should not be exclusive or restrict cooperation with third parties, raising concerns over sovereignty and regional geopolitics.
Australian Prime Minister Anthony Albanese has promoted PNG's entry into the NRL by 2028 as part of a broader diplomatic strategy, coinciding with the treaty's development.
The approval of this treaty signifies a significant deepening of security ties amid ongoing regional security developments and strategic negotiations.
Domestic critics within PNG, including former defense officials, have warned about potential long-term constitutional and geopolitical risks, especially regarding China's influence.
