The Pacific Islands have become a stage for a growing geopolitical contest between the United States and China. Each nation is deploying high-profile naval assets in the name of humanitarian cooperation.
While these missions are framed around disaster preparedness, medical aid, and regional partnerships, they also serve as powerful symbols of influence in the South Pacific. This blog post explores the latest deployments and how they connect back to Vanuatu’s place in this unfolding dynamic.

U.S. Naval Presence: The USS John L. Canley’s Pacific Partnership
Launched in 2006, the Pacific Partnership is the U.S. Navy’s largest annual humanitarian mission. Its primary focus is on disaster preparedness, humanitarian assistance, and strengthening security ties with Pacific nations.
This year, the expeditionary sea base USS John L. Canley sailed into Palau to begin a journey through Micronesia, Papua New Guinea, Samoa, Fiji, Vanuatu, and the Philippines. The ship’s presence reflects Washington’s intent to deepen partnerships in communities vulnerable to climate change, natural disasters, and economic instability.
By hosting joint exercises, delivering aid, and engaging in training programs, the mission helps build regional capacity. It also reinforces U.S. influence in strategically significant waters.
Why the U.S. Focuses on Pacific Connectivity
The vast ocean region between Asia and the Americas is central to U.S. security interests. Ensuring access and stability is part of the Pentagon’s “island chain” strategy, a concept designed to deter military expansion by rival powers.
In practice, this means investing in relationships with Pacific nations. Missions like Pacific Partnership combine humanitarian relief with subtle strategic messaging.
China’s Harmony 2025 and the CNS Silk Road Ark
China has taken a highly visible role in Pacific humanitarian efforts, most recently with the deployment of the CNS Silk Road Ark. Visiting Nauru for the first time, the Chinese hospital ship offered 20 specialist medical services, many otherwise unavailable locally.
Over a thousand patients received treatment, with surgeries and diagnostics enhancing local healthcare capacity. The Harmony 2025 mission is not confined to the Pacific alone.
After visits to Fiji and Tonga, the vessel will eventually continue toward Latin America. These missions often come with gestures of friendship — infrastructure grants, technical training, and cultural exchange.
Washington views them as part of China’s expanding military and diplomatic footprint in the region.
Medical Diplomacy with Strategic Undertones
China’s presence in remote island nations serves multiple purposes. The healthcare assistance is valuable to communities with limited medical facilities.
Each port call builds political goodwill and establishes touchpoints for deeper engagement. This can shape long-term alliances that might favor Beijing’s interests in maritime and trade routes.
The South Pacific’s Geopolitical Balancing Act
Both U.S. and Chinese missions illustrate a reality in the South Pacific: humanitarian narratives are intertwined with strategic objectives. Island nations, many of which are small in population but large in maritime territory, must navigate a delicate balance between accepting much-needed assistance and safeguarding their sovereignty.
For countries like Vanuatu, this competition can bring tangible benefits — improved disaster response infrastructure, medical services, and stronger transport links. The challenge lies in ensuring these gains do not come at the cost of political influence being ceded to one power over the other.
What This Means for Vanuatu
Vanuatu’s inclusion on the current Pacific Partnership route means the USS John L. Canley will bring training, resources, and cooperative exercises to its shores. With its central position in Melanesia, Vanuatu is a strategic waypoint for both humanitarian aid and geopolitical interest.
As China and the U.S. intensify their engagement across Pacific waters, Vanuatu finds itself in a unique position to actively benefit from infrastructure development and medical assistance. Islanders and policymakers alike will need to remain vigilant, ensuring foreign presence aligns with local priorities.
Whether it’s through American-led disaster readiness drills or Chinese medical support, the key for Vanuatu is to harness these opportunities for the well-being of its people. At the same time, the country must steer clear of becoming a pawn in the wider Pacific chessboard.
