New Zealand and Papua New Guinea signed a defense cooperation agreement late Wednesday, deepening security ties as China's expanding influence reshapes the Pacific region and puts pressure on smaller nations navigating competing interests.
New Zealand Defence Minister Chris Penk and his Papua New Guinea counterpart Elias Kapavore signed a Statement of Intent on Defence Cooperation for 2026-2029 in Papua New Guinea, Penk's office said. The agreement will expand defense dialogue, training, military exercises and personnel exchanges.
"In an increasingly volatile world, Pacific nations like ours are stronger when we work closely together," Penk said in a statement.
Regional Security Architecture Under Strain
The deal adds to a quickening push by Australia, New Zealand and the United States to lock in Pacific security ties as China expands its diplomatic, policing and infrastructure footprint across the region. Washington signed a defense cooperation agreement with PNG in 2023 that gives U.S. forces easier access for training and infrastructure work. Australia has followed security deals with PNG and Vanuatu with a new mutual-defense pact with Fiji, branded the Ocean of Peace Alliance, that officials have said could open to other Pacific nations.
The flurry of deals follows concern among Western-aligned governments that while Beijing was unable in 2022 to secure a region-wide pact with Pacific island nations, it has gained ground through policing and security ties, including with the Solomon Islands. PNG's recent move to close Taiwan's office in Port Moresby has further underscored the pressure on Pacific governments as they try to balance security support from traditional partners with economic ties to China.
High-Stakes Diplomacy in Manila
At a regional gathering in Manila led by the Association of Southeast Asian Nations, U.S. Secretary of State Marco Rubio and Chinese counterpart Wang Yi discussed a visit to the U.S. in September by Chinese President Xi Jinping. Rubio said he and Wang discussed at length the need to lay the groundwork for a "very positive visit" by Xi, and it was their job to manage the big differences between the two countries and ensure they didn't get out of control.
Wang, on his part, demanded that the U.S. "respect China's core interests ... effectively manage differences and disagreements, and address China's legitimate concerns," according to an official Chinese summary, which called the meeting "pragmatic, positive, and constructive." Wang and Rubio agreed to "make sound preparations for the next stage of high-level exchanges," Wang's ministry said in a statement.
The broader ASEAN meeting in Manila came amid a flare-up in the conflict between the U.S. and Iran, and while tensions simmered between Beijing and close U.S. ally the Philippines over an incident in the South China Sea on Monday that led each to summon the other's ambassador.
Competing Claims and Regional Tensions
Meeting with foreign ministers of ASEAN, who expressed concerns about the Middle East war, Rubio put the blame squarely on Iran. "The problem we're having right now is that they're not serious about talks," he said. "If they're serious, we're serious. If they're not, then we will do what's necessary to protect our interests, and also the interests of our allies."
He stressed that Iran couldn't be allowed to control the Strait of Hormuz, as it could set a dangerous precedent for other parts of the world.
Rubio's remarks followed his opinion piece in Philippine media on Tuesday that aimed at Beijing's conduct in the South China Sea, warning of "dire new threats" if those waters were to "fall under the control of a power willing to use commerce as a geopolitical weapon." Beijing claims sovereignty over almost the entire South China Sea via a line on its maps that cuts into the exclusive economic zones of Brunei, Indonesia, Malaysia, the Philippines and Vietnam, and is at the center of long-running disputes over a multitude of islands and features.
Australia's Foreign Minister Penny Wong said Monday's altercation between China's coast guard and Philippine navy personnel in the South China Sea was risky and destabilizing. "The countries of the region have a choice to make about how we all respond to that," Wong told reporters.
China's foreign ministry spokesperson Lin Jian said Australia had no right to intervene in the South China Sea issue and urged relevant countries to stop stirring up tension and inciting confrontation.
Why This Matters:
Pacific island nations are caught between competing powers at a moment when their sovereignty and economic futures hang in the balance. The rapid succession of defense agreements reflects the reality that smaller nations need multilateral support to maintain independence while managing relationships with both traditional partners and China. Monday's South China Sea incident, just three days ago, shows how quickly diplomatic tensions can escalate into physical confrontations that threaten regional stability. For Pacific governments trying to secure development aid and infrastructure investment while preserving territorial rights and democratic governance, the choices they're being asked to make will shape the region's security architecture for decades. The pressure on PNG over Taiwan's office closure demonstrates how economic dependency can translate into political leverage, raising questions about whether international frameworks can protect smaller nations' ability to chart their own course.
