To prevent corruption, most of diplomats were forced whenever abroad to carry with them during past 30 years a audio recording device - black box

I remember Iranian Foreign Minister Hossein Amir-Abdollahian to even request from whomever when abroad to have his recordings modified before one would return back to Iran - possibility, however, also exists it might have been Israeli setup and not real Iranian Foreign Minister Hossein Amir-Abdollahian that was used on opportunity. Both sides appeared were involved within very very short time - too short that it would be impossible to ignore + Iranian Foreign Minister Hossein Amir-Abdollahian was so nice that he suggested me how he have done times before without experiencing any problems what makes whole thing a bit more fishy. Stuff like this is nowhere written about on internet. Nobody is allowed to talk about.

Recordings of diplomats on such missions are afterwards reviewed by security departments from whichever countries those are - synchronized with time spent abroad to ensure absolute anti corruption compliance.
