Vietnam Accelerates Spratly Island Building Amid Growing Regional Tensions
5/9/2026, 7:02:04 AM
Historical Context of South China Sea Claims
The Spratly archipelago in the South China Sea is claimed in whole or in part by Vietnam, China, Brunei, Malaysia, and the Philippines. China asserts sovereignty over almost the entire sea, a stance that overlaps with the other claimants. In early 2025, Vietnam’s artificial-land building appeared to be narrowing the gap with China’s extensive reclamation, but subsequent Chinese activity at Antelope Reef expanded its lead.
Scale of Reclamation and Infrastructure
According to the Asia Maritime Transparency Initiative (AMTI) at the Center for Strategic and International Studies (CSIS), Vietnam added 534 acres (216.1 hectares) of reclaimed land in the past year, bringing its total artificial land in the Spratlys to roughly 2,771 acres (1,121 hectares). Reef destruction associated with Vietnam’s projects now covers about 4,120 acres (1,667 hectares). The nation has also constructed three new harbors at Grierson Reef, Petley Reef, and South Reef, raising its total number of harbors to 15, with 11 built since 2021. Initial work on a likely harbor is visible at Landsdowne Reef. China’s parallel efforts total approximately 5,460 acres (2,209 hectares) of artificial land and 6,224 acres (2,518 hectares) of reef damage.
Key Actors and Their Positions
- Vietnam (Hanoi) – Pursuing land reclamation and infrastructure to strengthen its presence in the Spratlys.
- China (Beijing) – Opposes Vietnam’s activities, labeling Barque Canada Reef as Chinese territory.
- AMTI/CSIS – Provides the data underpinning the reported figures.
- Vietnam’s Washington Embassy – Has not responded to requests for comment.
Environmental and Strategic Implications
The expansion has intensified environmental concerns, with additional reef destruction reported alongside the new harbors. The increase in Vietnamese harbors, now totaling 15, occurs while China’s reclaimed area remains larger, reflecting the ongoing disparity in artificial land between the two countries.
Official Statements & Responses
China’s position was summarized as opposition to Vietnam’s construction at Barque Canada Reef, asserting that the feature is Chinese territory. Vietnam’s Washington embassy declined to comment when approached for a statement.
Criticism & Opposition
The expansion has caused additional environmental damage, including degradation of coral reefs and associated marine ecosystems from dredging and landfill operations. China has opposed Vietnam’s construction activities at Barque Canada Reef, calling the feature Chinese territory, underscoring the broader contest over sovereignty and resource rights in the Spratly region.
Broader Regional Impact
The three newly constructed harbors raise Vietnam’s total to 15, compared with China’s continued expansion at Antelope Reef, which brings China’s artificial land to roughly 5,460 acres. The juxtaposition of Vietnam’s growing infrastructure and China’s larger reclaimed area maintains the existing disparity in artificial land between the two claimants.
Conflicting Reports & Information Gaps
Both source articles present identical quantitative data, differing only in unit conversion (acres versus hectares). No direct quotation from Vietnamese officials is available, and the Vietnam embassy’s silence leaves a gap in official Vietnamese commentary. The reliance on a single think-tank report limits independent verification of the figures.
