Hence, why the construction took a halt during 1 year. They were selling at a discount to break even, the government was indeed talking about opening borders (we were already inside Thailand at that time, not buying from abroad).
We visited the construction site and saw ~10 workers, everything seemed real, like a thing slowly getting back to normal.
I have all the reasons to believe now, that these "workers" were just paid to be here. The company was advertising, getting batches of potential investors, and making a "Potemkin" construction site.
They never had any intention of ever finishing the project.
