Pacific security vs climate pressure: Fiji and Australia pushed a new “Ocean of Peace” baseline for peace, security and economic cooperation, but China’s nuclear-capable submarine missile test has jolted the region and sparked a chorus of condemnation from leaders including Tonga and Solomon Islands. Nauru and the “blue continent” concern: The reported splashdown area—between Nauru, Tuvalu and nearby islands—has been framed as a direct hit to shared ocean stewardship, with China calling it routine and “not directed” at any country. Regional diplomacy accelerates: New Zealand says it will engage to join the Ocean of Peace Alliance, while Australia signs more defence deals across the Pacific. Deep-sea mining rules under fire: The UN seabed regulator defended its authority as mining firms seek to halt an investigation, and campaigners warn that a new high-seas treaty could exempt deep-sea mining from stronger environmental impact checks. El Niño risk for island weather: Forecasters warn El Niño is underway and may be very strong, raising the odds of more intense storms and longer, hotter conditions during cyclone season. War remnants still threaten communities: Australia’s Operation Render Safe continues clearing explosive remnants in Papua New Guinea, including work that previously reached Nauru. Local sustainability wins: PNA leadership reaffirmed its PNG partnership to support sustainable tuna management and better value for Pacific fisheries.
