I was at Sihanoukville (Cambodia) around 5 years ago and was surprised to find what was seemingly a Chinese city. There was a lot of dust, construction, and the city seemed like it was being raised out of the ground really quickly. Massive Chinese casinos and hotels were around and locals reported some casinos didn't even let them in. There were some whispers about shady stuff too.
I suppose if I were to go there today I'd find there are no more dirt roads and that the city is "fully built" given the rate at which these things happen. Would be cool to see.
