The recent arrival of the Chinese research vessel Da Yang Hao in the Cook Islands signals a new chapter in the global race to tap into the ocean’s mineral wealth. With a mission centered on investigating the region’s deep-sea mining potential, this expedition is part of a broader geopolitical contest between major powers like China and the United States.
The seabed surrounding the Cook Islands holds vast deposits of polymetallic nodules rich in cobalt, nickel, manganese, and rare earth elements. These resources are vital for electric vehicles, energy storage, and advanced technologies.

The stakes also include environmental concerns and regional sovereignty. This makes the situation an evolving story with implications for the Pacific, including Vanuatu.
China’s Growing Interest in Pacific Mineral Wealth
The Da Yang Hao is operated by China’s Ocean Mineral Resources Research Association. It has long been linked to ambitious deep-sea exploration programs.
Its docking in the Cook Islands comes only months after the nation signed a controversial mining cooperation deal with Beijing.
Strategic Resources Beneath the Waves
Polymetallic nodules on the deep ocean floor contain key elements for modern industry:
- Cobalt – Essential for high-performance batteries used in electric vehicles.
- Nickel – Crucial in stainless steel production and battery components.
- Manganese – Used in steel manufacturing and battery chemistry.
- Rare earth elements – Vital for electronics, renewable energy systems, and defense technologies.
These resources are becoming increasingly valuable as nations accelerate their shift toward renewable energy and electrification. China’s presence in the Cook Islands reflects a long-term strategy to secure supply chains resistant to geopolitical shocks.
Competition Between Global Powers
The United States has also signed a separate research agreement with the Cook Islands. This underlines the region’s strategic importance.
This parallel engagement highlights ongoing competition in the Pacific. It is a theater where resource security and influence overlap.
Past Incidents and Geopolitical Tensions
The Da Yang Hao has not been without controversy. In 2021, Palau accused the vessel of entering its exclusive economic zone without authorization, raising suspicions about whether “research” missions may also serve surveillance purposes.
Such incidents underscore the complexity of balancing scientific collaboration with national security.
Environmental Risks and Regulatory Challenges
Despite decades of scientific surveys, no country has yet begun commercial-scale deep-sea mining. One major reason is concern from environmentalists and marine scientists who warn of profound impacts on biodiversity.
Disturbing fragile ecosystems on the ocean floor could trigger cascading effects throughout the food chain.
Global Governance of Deep-Sea Mining
The International Seabed Authority continues to debate rules and standards for mining activities beyond national jurisdictions. For smaller island nations, aligning with powerful partners like China or the US offers opportunities for expertise and investment.
This also raises questions about environmental stewardship and the long-term consequences of industrial exploitation.
Implications for Pacific Island Nations
The Cook Islands’ decision to welcome the Da Yang Hao exemplifies how Pacific nations are weighing economic opportunities against ecological risks. Participation in mapping and sampling projects may build local scientific capacity.
It also ties countries into the ambitions of rival superpowers.
Connections to Vanuatu
For Vanuatu, this development serves as a reminder of the interconnected nature of Pacific resource politics. While Vanuatu has not formally engaged in deep-sea mining, its waters are part of the same vast oceanic environment.
Understanding the dynamics at play in the Cook Islands could help Vanuatu navigate future offers of resource exploration.
Vanuatu’s commitment to sustainable development and marine conservation positions it uniquely. By monitoring regional initiatives like China’s expedition, Vanuatu can foster informed discussion about balancing economic gains with ecological responsibility.
In a Pacific increasingly shaped by resource competition, such foresight will be essential to protect both the ocean and the livelihoods it supports.
