Well, I wouldn't know about that. However I just looked it up and there's a tourist attraction that consists of 8000 skulls in a glass box. I don't like skulls. So no Cambodia for me just my opinion, there are MANY other countries I would much rather visit.
You can decide if you want to go to that place or not. No one will point a gun to your head and force you to go there
Going there in ~30 years when it'll be a cleaner place, have more English speakers and everything. Right now it looks a bit too messy for me.. I wouldn't feel fine visiting one of the poorest countries in the world.
