Possibly but I wouldn't be surprised if they were simply diverted to some foreign holding company. How much actually went in to building the resort is anybody's guess.
This sort of rip off is as old as the hills.
Suppose I start a website which I am going to run from abroad. I seek investors promising a return of 10% or more and create a $2 web development company in sinkieland to collect your money.
Once the money leaves Singapore's shores I can do whatever I want with it. My $2 sinkie company will never reflect how much I am actually making. It most certainly won't be reporting a profit.
