A landmark joint marine research voyage, organized by China's Ministry of Natural Resources (MNR) and the Cook Islands Seabed Minerals Authority, has been completed, giving fresh momentum to the two countries' expanding "blue partnership."

The expedition, conducted from October 31 to November 9, 2025, marks a significant step forward in bilateral cooperation in ocean research. Scientists from both sides worked together in the Cook Islands' Exclusive Economic Zone, conducting wide-ranging surveys to better understand local marine conditions and the surrounding seabed environment.

During the voyage, the team collected video records and environmental samples at key locations, building a clearer picture of underwater ecosystems and the natural features of the deep sea. The mission produced first-hand information that will help fill long-standing data gaps and support future assessments of the region's ocean resources and environmental health.

As the first collaborative research effort of its kind between the two nations, the voyage lays an important foundation for deeper cooperation in ocean exploration, marine conservation and capacity building in the years ahead.
