Construction of a new coastal town named Can Gio and a $4.7 billion port is underway in Vietnam’s Ho Chi Minh City region. This development is raising concerns about the impact on the area's mangrove forests, which serve as a natural buffer against rising sea levels and intensified storms. Scientists warn that the construction, which includes roads, bridges, and a sea-crossing route, could disrupt the water flows that sustain the mangroves. These forests, which were replanted after being nearly destroyed during the Vietnam War, are vital for sheltering marine life, absorbing carbon, and protecting the city of 10 million people. A 2026 study by Vietnamese scientists indicated that about 80% of Ho Chi Minh City's area is vulnerable to flooding. The Vietnamese government estimates that rising seawater already costs the city approximately $57 million per year. The development is being undertaken by Vingroup, Vietnam's largest company, on reclaimed land. Authorities view Can Gio as a key logistics hub and tourism destination. However, residents in the fishing town of Can Gio are divided. Some anticipate new job opportunities, while others, like a resident named Muoi who spoke on condition of anonymity, report that construction has already negatively impacted fishing and led to blocked drainage, worsening floods and polluting local waters. ## Disagreement on mangrove clearing Vietnamese officials have stated that the project is located outside the core, strictly-protected area of the Can Gio Mangrove Biosphere Reserve. However, reports indicate that in September, Ho Chi Minh City authorities sought approval to clear 4.57 hectares (11.3 acres) of mangrove forest in the reserve's buffer zone for a metro link. The Vietnamese government did not respond to queries from the Associated Press. ## What the coverage left out None of the left-rated, centre-rated, or right-rated reports mention the specific details of Vingroup's Green Paradise development, including its size of 2,870 hectares (more than 7,000 acres) or that it is being built by the conglomerate's property arm, Vinhomes. The left-rated reports also do not mention the specific figure of $4.7 billion for the port construction, though they do mention the port itself. The right-rated report does not mention the 2026 study on flood vulnerability or the Vietnamese government's estimate of annual costs from rising sea levels. ## Who covered it Shares of the 12 covering outlets with a published leaning rating: - Left: 67% (8) - Centre: 25% (3) - Right: 8% (1) 1 of 13 covering outlets carried no usable leaning rating and were excluded from those percentages. Coverage measured 2026-10-22T06:30:20.222000+00:00. **Coverage watch:** developing. Checked 8 times; 0 checks found a material change. Most recently checked 2026-10-22T07:15:30.375Z. ## How the sides framed it ### Left - Left-rated reports led on the threat to the mangrove forest and its role as a buffer for Ho Chi Minh City. They highlighted the potential disruption to water flows and the ecosystem due to construction projects, including a new seaside city and port. These reports noted the city's vulnerability to flooding, citing the 2026 study and the annual cost of rising sea levels. They also included concerns from residents about the impact on livelihoods and environmental damage, quoting one resident who described the area as no longer "magical." The clearing of mangrove forest for infrastructure was also mentioned, alongside expert warnings about the scale of the project and potential pollution. ### Centre - Centre-rated reports focused on the construction of the new coastal town and port and the risk posed to the mangrove forests that protect Vietnam's largest city. They detailed the city's vulnerability to flooding, referencing the 2026 study and the government's estimate of annual costs from rising sea levels. These reports also covered the division among local residents regarding the development's impact on jobs and livelihoods, and included expert opinions on the importance of mangroves and the potential consequences of disrupting water flows. The historical replanting of the mangroves after the Vietnam War was also noted. ### Right - The right-rated report led with the threat posed by construction projects to the mangrove forest that acts as a protective buffer for Vietnam's biggest city. It stated that these projects put the forest at risk as the city expands and its coastline is reshaped. The report also mentioned that mangroves play a vital role in buffering coastlines from storms, flooding, and erosion, and that they support fisheries and store vast amounts of greenhouse gases. **Provisional coverage gap:** right. The watch is not closed, so this is not yet a settled blindspot finding. ## Factuality profile of the covering outlets These are published factuality ratings of the outlets, not a verdict on whether this story or its claims are true. - mixed: 1 - high: 5 - unknown: 1 - veryHigh: 6 ## Verification scope This page compares coverage and scores the source reporting.

This development also includes roads, bridges, and a sea-crossing route, with plans for housing, shopping, and entertainment areas. **Why are the mangrove forests in Can Gio important?** The mangrove forests act as a vital natural buffer protecting Ho Chi Minh City from rising sea levels, storms, and flooding. They also support marine life, absorb carbon emissions, and help maintain coastal stability. **What are the potential consequences of the construction projects?** Scientists warn that the construction could disrupt water flows essential for the mangroves' survival, weakening the city's natural defenses. This could increase Ho Chi Minh City's vulnerability to flooding, which already affects about 80% of its area. **How are local residents affected by the construction?** Residents are divided. Some anticipate new job opportunities from the development. Others report negative impacts, such as disruptions to fishing, blocked drainage leading to worse floods, and pollution affecting local farms and oyster beds. --- MediaBias News — https://mediabias.news.
