The main attraction of Cambodia vs Thailand is the easy hassle free visa options, esp if you're 55 and older.
One downside, having spent nearly 2 mos there, is the near constant air pollution and rubbish everywere at the roadside.
Worrying is the surging CCP influence/investment.
It is not necessarily a cheaper option overall; however, beer is cheaper than in Thailand.
Some expats might be deluding themselves thinking that Cambo is a much cheaper place to live than Thailand?
