The VND165 trillion ($7 billion) Ha Long Green project in the northern province that is home to world famous natural attraction Ha Long Bay, would cover an area of nearly 3,200 hectares.

It would consist of 55,300 properties for both residential and commercial purposes, as well as schools and parks.
Quang Ninh has been receiving significant increase in investments in recent years. It is home to Vietnam’s first private airport - the Van Don International Airport – which began operations last December.

Quang Ninh was the most competitive province in Vietnam last year for the second time in a row, according to the Provincial Competitive Index (PCI) 2018 survey results released in March.
