Bon Bon's website reveals little: some of the text has been cribbed from other sites, and some their projects appear to be fake. Yet the photographs are instructive, showing Bon Bon World staff in meetings with a series of Cambodian officials and prominent Cambodian People's Party leadership.
Interestingly, Bon Bon World also lists the questionable Koh Puos development project as part of their portfolio of projects.
AltMapCambodia now reveals internal Bon World documents (large PDF) showing the location of concessions apparently negotiated between Bon Bon World and the Kingdom of Cambodia.
