The US factory is expected to build 150,000 EVs annually.
"VInFast has received one of the important permits that will allow it to begin construction on a planned $4 billion assembly facility in North Carolina.

The Vietnamese car manufacturer has been awarded an ‘Air Permit’ which it says will allow it to start construction on phase 1 of the factory. The North Carolina Department of Environmental Quality’s website reveals that the Air Permit application was made in December and that it was approved on February 9. VinFast says it will “start construction soon.”

Reuters notes that phase 1 of the project will see the company invest some $2 billion into a factory that will be able to produce 150,000 vehicles a year. The second phase will focus on battery production."
