Mokkona Green Box Seen Anywhere In Bkk? Company = Dead

I have seen Duang Dee somewhere - I will search it out if I cannot find the Moccona Green. I think it has two blends, one is "strong" and the other something else. Normally this very much puts me off. I like the blends to reflect Western named roasts (French, Italian, Espresso...). One thing I don't get is how Arabica is a blend/style - it is a bean. Sadly, appears much of this coffee is Robusta. I guess that is why its B100 a bag.

Curious why tribes, Cambodia and Vietnam grow Robusta and not Arabica. Maybe climate?? Too lazy to google it.
