I like this image because it symbolizes the different worlds which coexist.
From top to bottom: the Wat Koh Pagoda, a building built around it inside the Pagoda complex which can be a school or a regular house, a generator, a car a small motorbike.

The Pagoda symbolizes the rich cultural and spiritual heritage of this country, the house its struggling for decent living conditions.

The generator is used by the nearby "Big A" supermarket (mainly for air-conditioning and freezers). The supermarket is very modern, with imported products from all around the world (Thailand, Singapore, Europe, United States...) All I could find in the store that was not imported was some beer brewed in Sihanoukville. I'm not sure about vegetables. Yogurt, toilet paper, soap are all imported.

Some people have a car (a large 4-wheel drive if they can afford it) and can try to live in the "industrialized" way by buying there grocery in a modern supermarket. But the infrastructure is not there (as shown by the generator), the produce are imported therefore this cannot grow to serve more than a happy few.

Most people use the motorbike as means of transportation inside the city.
