How Many Foreigners Know About Cambodia

What I believe foreign people know and think about Cambodia.
In my opinion, the good thing in Cambodia for the foreign people is the interesting view of the beach in Kompong Som province and the famous landmark in Siem Reap (Angkor Wat). And the bad thing is the environment is not so clean and a lot of robbers. And about the food, some of the foreigners would like to try or taste some of the amazing Cambodian food.

I think many foreigners would like to learn some Khmer greeting words like Sorry, Please, Excuse me, Thanks and something else......!
However, I wonder that the foreigners come and visit Cambodia more than before!!
