China has advised Papua New Guinea against signing any defense agreement that could limit cooperation with third parties. This warning comes as Australia seeks to finalize a significant defense treaty with PNG. In a recent social media post, the Chinese embassy in PNG emphasized the importance of the country's independence, urging it to "properly handle issues bearing on its sovereignty and long-term interests."

China is a key trade and economic partner for Papua New Guinea. Defense experts in the island nation have expressed concerns that a high-level pact with Australia could strain relations with Beijing.

The anticipated defense treaty, known as the Pukpuk Treaty, would establish formal military alliances between Australia and PNG. It would commit both nations to defend each other in the event of a military attack. Additionally, the treaty stipulates that activities with third parties should not compromise its objectives.

However, the treaty was not signed as planned this week. Instead, Australia and PNG issued a communique in place of the formal agreement. Prime Minister Anthony Albanese explained that the delay was due to PNG's national cabinet failing to reach quorum during a meeting on Monday, as ministers were attending independence celebrations.

Leaders from both countries expect to finalize the treaty in the coming weeks. In its social media statement, the Chinese embassy acknowledged PNG's right to enter into bilateral agreements but cautioned that such deals should not be exclusive. The embassy stated, "Nor should it restrict or prevent a sovereign country from cooperating with a third party for any reason. It should also refrain from targeting any third party or undermining its legitimate rights and interests."

This week, PNG Prime Minister James Marape announced that the country's defense minister, Billy Joseph, would engage in discussions with China and Indonesia regarding the treaty's parameters. The Indonesian government has been contacted for a response, but its Ministry of Foreign Affairs has declined to comment.
