I was just asking this question at the Singapore consulate in San Francisco yesterday (btw.. friendliest and most helpful consulate I've ever been to). I was under the assumption that the VFTF was still good for Chinese and I wouldn't need a visa for my 36 hr transit. However when I asked at the visa counter, the officer said Chinese passport holders do require a visa for entry even if for transit. So I applied for my visa and they will have it ready by next friday. Only one day before my flight to SIN ;-)

I'll ask the same question at immigration when I arrive and let you all know what they say. I still have a feeling they might allow entry on a case by case basis.
