According to a report released by the Centre for Strategic and International Studies (CSIS) on August 22nd, the construction focuses on Liumen Reef, Guiying Reef, Dong Reef, qiong Reef, and Bolan Reef.These projects involve extensive dredging, silting, and reclamation work, transforming previously small reefs and low-tide elevations into artificial islands. Just four years ago, many of these locations consisted of only basic bunker installations.
The projects aren’t limited to new construction. Vietnam is also undertaking a new phase of expansion on Amboyna Cay, grierson Reef, and West Reef, areas where medium-scale island building had already taken place. This demonstrates a clear commitment to solidifying its position in the region, potentially altering the existing geopolitical landscape.
A Comparative Look: Vietnam vs. China
Data from CSIS reveals that, as of March 2025, Vietnam’s artificial island construction has reached approximately 70% of the area built by China in the same region. The continuing work on the eight new islands and reefs is expected to close the gap, potentially enabling Vietnam to equal or even surpass China’s overall island-building scale.This escalation has prompted international observation and concern.
Satellite imagery also indicates the emergence of infrastructure, including ammunition depots, on islands and reefs claimed by Vietnam, signaling a move toward establishing a more robust military presence. Dredging operations are nearing completion in several key areas, further accelerating the pace of development.
Did You Know? The South China Sea is estimated to hold approximately 11 billion barrels of oil and 190 trillion cubic feet of natural gas, making it a strategically and economically vital region.
Regional Implications and Overlapping Claims
China asserts sovereignty over nearly the entirety of the south China Sea, a claim that is contested by Brunei, Malaysia, the Philippines, and Vietnam. China’s previous large-scale island-building efforts have drawn opposition from the United States and its allies, who view the activities as destabilizing to the region. This latest development by Vietnam adds another layer of complexity to an already delicate situation.
The escalating construction raises questions about freedom of navigation and potential military escalation in the South China Sea. Regional stability relies on diplomatic solutions and adherence to international law,but the current trajectory suggests increasing tension.
| Country | Approximate Artificial Island area (as of March 2025) | Key Focus Areas |
|---|---|---|
| China | 100% (Baseline) | Extensive reclamation and military installation across multiple features. |
| Vietnam | 70% of China’s Area | Expansion of existing features and new island construction in the Nansha Islands. |
Pro Tip: Stay informed about the South China Sea dispute by consulting resources from reputable think tanks like CSIS and the Council on Foreign Relations.
The South China Sea: A Historical Overview
The South China Sea dispute is rooted in historical claims and overlapping territorial assertions. For centuries, various nations have navigated and utilized the sea’s resources. The finding of potential oil and gas reserves in the 1970s substantially intensified the competing claims. The United Nations Convention on the Law of the Sea (UNCLOS) provides a framework for resolving maritime disputes, but interpretations and implementation remain contentious.The ongoing developments highlight the need for continued diplomatic efforts to prevent further escalation and ensure regional peace and stability.
Frequently Asked Questions about Vietnam and the South China Sea
- What is the extent of Vietnam’s claims in the South China Sea? Vietnam claims sovereignty over the Paracel and Spratly Islands, and also related maritime features.
- how does China respond to Vietnam’s island-building activities? China has consistently protested against the actions of other claimant states, but has continued its own construction.
- What role does the United States play in the South China Sea dispute? The U.S. maintains a policy of neutrality regarding sovereignty claims, but supports freedom of navigation and opposes any attempts to unilaterally alter the status quo.
- What is UNCLOS and how does it relate to the south China Sea? UNCLOS is an international treaty that establishes a legal framework for all ocean and sea-related matters, but interpretations of its provisions are central to the dispute.
- What are the potential consequences of escalating tensions in the South China sea? Increased military presence and assertive actions could lead to miscalculations and accidental confrontations, potentially destabilizing the region.

What are teh potential implications of Vietnam’s accelerated land reclamation efforts for the regional balance of power in the South China Sea?
Vietnam’s Land Reclamation in Nansha islands Outpaces China: US Think Tank Analysis
Recent Developments in the Spratly Islands
Recent analysis from US think tanks indicates a important shift in land reclamation activity within the Nansha Islands (Spratly Islands). While China has historically dominated such efforts, Vietnam is now demonstrating a more rapid pace of advancement, particularly on features it already occupies. This trend has implications for regional security, maritime claims, and the balance of power in the South China Sea.
Vietnam’s Accelerated Reclamation Efforts
Vietnam’s activities, while smaller in overall scale compared to China’s earlier massive projects, are strategically focused and increasingly assertive. Key observations include:
Spratly Island Expansion: In March 2017,reports surfaced detailing Hanoi extending its sole runway and adding new hangars on Spratly Island itself. This suggests a focus on enhancing its logistical capabilities and potential military presence. (Source: https://www.rand.org/pubs/commentary/2017/03/china-tolerating-vietnams-south-china-sea-activities.html)
Fortification of Existing Outposts: Several Vietnamese-held features have reportedly undergone fortification, including the construction of defensive structures and improved infrastructure.
Subtle but Consistent Growth: Unlike China’s large-scale, highly visible island-building, Vietnam’s approach has been more incremental and less publicized, making precise tracking challenging. However, satellite imagery analysis confirms consistent land reclamation over the past several years.
Focus on Logistics & Airpower: The runway extension on Spratly Island is a prime example of Vietnam prioritizing capabilities that support sustained operations and potential air defense.
China’s Response: A Calculated Tolerance?
Interestingly, China appears to be tolerating Vietnam’s current level of activity, at least temporarily. Several theories attempt to explain this:
Strategic Prioritization: China may be focusing its resources on consolidating its gains in the Paracel Islands and other areas of the South China Sea, viewing Vietnam as a less immediate threat.
Avoiding Escalation: A direct confrontation over relatively small-scale reclamation efforts could escalate tensions unnecessarily.
Maintaining Regional Stability: China might be attempting to project an image of restraint to avoid further alienating ASEAN member states.
Monitoring and Countermeasures: It’s highly probable that China is closely monitoring Vietnamese activities and developing countermeasures, potentially including increased naval patrols and assertive diplomatic pressure.
Implications for Regional security & Maritime Disputes
vietnam’s increased activity has several key implications:
Strengthened Vietnamese Claims: Land reclamation reinforces Vietnam’s claims to sovereignty over the nansha Islands, bolstering its legal and strategic position in the ongoing dispute.
Enhanced Military Capabilities: Improved infrastructure allows Vietnam to project power further into the South China Sea and respond more effectively to potential threats.
Increased Risk of Confrontation: while China currently appears tolerant, the potential for miscalculation or accidental clashes remains a significant concern.
ASEAN Dynamics: Vietnam’s actions could encourage other claimant states (the Philippines,Malaysia,Brunei) to pursue similar strategies,further complicating the situation.
US Involvement: The United States, committed to freedom of navigation in the South China Sea, is likely to closely monitor developments and potentially increase its military presence in the region.
Key Features & Islands Involved
The following islands and features are central to the land reclamation and dispute:
Spratly Island (Nansha Dao): The largest of the Spratly Islands, and the focus of Vietnam’s runway expansion.
Southwest Cay (da Chau Vu): A Vietnamese-held feature that has seen significant infrastructure development.
Mid Reef (Da Trung): Another Vietnamese-occupied island undergoing fortification.
Subi Reef (Da xu Bi): While primarily controlled by China, nearby Vietnamese features are being developed.
Fiery Cross Reef (Da Hoa Van): A Chinese-held feature, serving as a point of comparison for reclamation scale.
The Role of International Law & the UNCLOS
The South China Sea dispute is heavily influenced by the United Nations Convention on the Law of the Sea (UNCLOS). Vietnam, a signatory to UNCLOS, bases its claims on historical rights and the proximity of the islands to its coastline. China’s expansive “nine-dash line” claim, though, is not recognized by many international observers and is a major source of contention. Land reclamation activities, regardless of the claimant, raise questions about compliance with international law and the preservation of maritime environments.
Future Outlook: Monitoring and Potential Escalation Points
The situation in the Nansha Islands remains fluid and unpredictable. Key factors to watch include:
China’s Response: Will China maintain its current level of tolerance, or will it take more assertive action to counter Vietnam’s activities?
Vietnam’s Continued development: Will Vietnam continue to accelerate its reclamation efforts, and will it expand its activities to other features?
