On major intersections of Phnom Penh you can see sales of just about everything including "soda pop." I wouldn't drink this particular soda. In fact, if you aren't Khmer I would definitely ask before even buying from a "soda pop" sales person.

What's in the bottles here is gasoline. Gas is sold by the liter for moto drivers in need along with the two or four stroke oil that needs to be mixed in. In Phnom Penh even in the center city you can buy gas in this fashion...this stand happens to be at the corner of Mao Tse Toung and Phreah Norodom, a major intersection in the urban landscape.
