I am aware that there were several collaborations between the National Bank of Cambodia and other entities, to produce banknotes. For example Lanqart was involved with at least one note and GSI supplied the ink for part of the 30000 Riel note.
I would like a definitive list of who printed each banknote after 2000. The cherry on top would be if I could find out who collaborated on inks, security strips, papers etc.
I have 95 banknotes from Cambodia and that number will increase. They have a lovely design and they look fantastic under UV!
