Don't you love when the worlwide terrorists go to foreign sovereign nations to make arrests? Rememebr Kim dotcom? Same crap.
It's pretty much par for how extradition is supposed to work.
I'm in favour of extradition provided due process is respected, no cruel or unusual punishments are involved, and the crime is a crime in both juridsictions (and not political).
IIRC, the citizenship of the person to be extradited is completely irrelevant, so having a "banana republic citizenship" would no change a thing. Countries indite foreign citizens all the time, a notable recent example is Meng Wanzhou.
Who are you talking about?
