Singapore is ~$300 billion.
Not sure why Indonesia's GDP keeps getting over-estimated by such a dramatic amount in this thread.
Sorry, that was just a bit careless looking up of numbers. $850 billion is nominal GDP, $2.8 trillion is the PPP adjusted figure.
For Singapore, the nominal and PPP adjusted values are much closer to each other ($300 billion vs. $450 billion).
