An almost complete beachfront villa in the project is gradually deteriorating after being left untouched for three years.
The work began in 2019 and was scheduled to be finished in 2021, but the developer got an extension until July 2023.
Nguyen Cu, owner of a restaurant next door, said when the project was announced, locals were excited that it would attract guests and create more jobs.
"The land was handed over for the project more than 10 years ago, but now it lies abandoned, which is a huge waste.
"We hope for early construction, cleaning up of the beach and the arrival of tourists."
