I'd think that Argentina of the junta wasn't quite as important economically as Taiwan is now, but I'd have to research to compare that. I would also imagine Taiwan's HDI is quite higher to Argentina's was back then. Another factor of note is that the junta was going through a shaky transitional period while Taiwan's democracy is fairly stable. Not to mention that while mostly diplomatically unrecognized, democratic Taiwan probably isn't a pariah in the same way a military autocracy like Argentina was.
