How many years ago was that now, though? Just because a plan doesn't work out for one zoo at one time doesn't mean it won't for another zoo at another time. One could easily have said "Ask ABQ how well that plan turned out" when SDZ went after Tasmanian Devils. I suspect it will only be a matter of time before someone imports snub-nosed monkeys, though I do doubt it will be a US zoo.
That's a fair point, but the takeaway I got from that quip (and that I agree with) is that dealing with the Chinese government on animal imports or exchanges can be very unpredictable. They have been known to do a 180-degree turn because of things that aren't even related to the zoo or the process - in the case of the monkeys and LA, I think it was a diplomatic spat. This isn't unique to China by any means, but it's a known issue and makes it hard for any zoo to count on plans involving them to pan out.
