Naval Diplomacy in a Shifting Indo-Pacific: The USS Cincinnati’s Cambodia Visit and Future Trends
The recent port visit by the USS Cincinnati (LCS 20) to Cambodia’s Ream Naval Base marks a significant moment in the evolving geopolitical landscape of the Indo-Pacific. This first U.S. warship visit since the base’s Chinese-backed expansion isn’t just a routine port call; it’s a calculated move reflecting the U.S.’s commitment to maintaining influence and fostering partnerships in a region increasingly shaped by China’s growing military presence. But what does this visit signal for the future of naval diplomacy and regional security?
The Ream Naval Base: A Focal Point of Strategic Competition
For years, Ream Naval Base has been at the center of speculation regarding its potential use by the People’s Liberation Army Navy (PLAN). While Cambodian officials insist the base remains under national control, the extensive Chinese funding and construction assistance have raised concerns in Washington. The completion of the expansion, including new piers and dredged waterways, dramatically increases the base’s capacity to host larger vessels – including those belonging to the PLAN. The USS Cincinnati’s visit, occurring just months after the expansion’s completion, is a direct response, demonstrating the U.S. is not conceding the region without a contest. This echoes similar strategic positioning seen in the South China Sea, where the U.S. Navy consistently conducts freedom of navigation operations.
Beyond Port Calls: The Future of U.S. Naval Engagement
The USS Cincinnati’s visit isn’t an isolated incident. The U.S. Navy’s continued engagement with Cambodia, exemplified by the USS Savannah’s visit in late 2024, suggests a strategy of sustained naval presence. However, future engagement will likely extend beyond simple port calls. Expect to see:
- Increased Joint Exercises: More frequent and complex joint naval exercises with Cambodia and other Southeast Asian nations like Vietnam and the Philippines. These exercises will focus on maritime security, disaster relief, and interoperability.
- Capacity Building Initiatives: The U.S. will likely increase its investment in training and equipping the Royal Cambodian Navy, enhancing its ability to patrol its own waters and contribute to regional security.
- Technological Cooperation: Sharing of maritime domain awareness technology, such as radar systems and surveillance platforms, to improve Cambodia’s ability to monitor its coastline and Exclusive Economic Zone (EEZ).
These initiatives are crucial, as Southeast Asian nations are increasingly seeking to diversify their security partnerships, avoiding over-reliance on any single power. A 2023 report by the Center for Strategic and International Studies (CSIS) highlighted this trend, noting a growing desire for a “hedging strategy” among ASEAN members.
China’s Response and the Potential for Escalation
China is unlikely to passively accept increased U.S. naval activity in the region. We can anticipate a continued expansion of PLAN presence in the South China Sea and potentially increased naval deployments to Cambodian ports. The proximity of the USS Cincinnati to a Chinese naval vessel at Ream, as reported by AFP, underscores the potential for friction. The risk of miscalculation or unintended escalation will remain a significant concern.
However, a full-scale naval confrontation is unlikely. China’s primary focus remains economic influence and asserting its territorial claims. A direct military clash with the U.S. would be economically damaging and politically costly. Instead, expect a continuation of “gray zone” tactics – activities below the threshold of armed conflict, such as harassment of foreign vessels and assertive maritime claims.
The Role of Littoral Combat Ships (LCS) in Regional Security
The deployment of the USS Cincinnati, an Independence-variant LCS, is noteworthy. LCS are designed for operations in coastal waters and are well-suited for missions like maritime security, anti-piracy, and humanitarian assistance. However, their capabilities have been debated, with some critics questioning their survivability in a high-intensity conflict.
Pro Tip: LCS are most effective when operating as part of a larger naval task force, providing a forward presence and supporting other, more heavily armed vessels. Their agility and shallow draft make them valuable assets for patrolling littoral zones and responding to asymmetric threats.
The U.S. Navy is adapting its LCS deployment strategy, focusing on leveraging their unique capabilities for specific missions and integrating them more effectively with allied navies.
The Broader Indo-Pacific Security Architecture
The situation at Ream Naval Base is symptomatic of a broader trend: the reshaping of the Indo-Pacific security architecture. The Quad (U.S., Japan, India, Australia) remains a key pillar of U.S. strategy, but Washington is also actively seeking to strengthen partnerships with other regional players, including Vietnam, Indonesia, and the Philippines.
Did you know? The U.S. recently signed a new defense agreement with the Philippines, granting U.S. forces access to additional military bases in the country, further bolstering its regional presence.
The success of these efforts will depend on the U.S.’s ability to demonstrate a long-term commitment to the region and to address the legitimate security concerns of its partners. Simply offering military assistance is not enough; Washington must also invest in economic development, diplomatic engagement, and cultural understanding.
