Chinese icebreaker sails deep into Palau's EEZ, raising security concerns
A Chinese research icebreaker entered Palau's exclusive economic zone for 14 hours, prompting the president to question its purpose and raise alarm over possible intelligence gathering.
During the final days of May, the Chinese ice-class research ship Ji Di penetrated roughly 74 kilometres into Palau's maritime zone and remained on a slow course for 14 hours. President Surangel Whipps Jr. described the uninvited entry as a breach of sovereignty and asked what the vessel was seeking. Built in 2024 for climate-related monitoring, the ship carries drones and submersibles that can chart the seafloor, a function that analysts say may also aid Beijing in future conflict scenarios involving Taiwan.
The incident follows a pattern of similar Chinese vessel activities reported in 2018, 2024 and 2025, including a July incursion shortly after a Chinese submarine-launched missile passed over Pacific islands. Think-tank Pacific Centre of Island Security logged sixteen Chinese research ships in the North Pacific this year, and scholars warn that the data collected could help map US submarine routes around Guam and Hawaii.
A 2024 CSIS study found most Chinese research vessels display suspicious behaviour, suggesting a broader geopolitical agenda. Palau has lodged a diplomatic complaint, but options to prevent further entries remain limited.
Why it matters
The episode highlights how civilian-labelled Chinese ships may be gathering data that could bolster Beijing's military planning in a strategically vital Pacific region.
