'Though Khmer territory is not considered extremely fertile by global stan- dards, the low population density has almost always allowed for the production of a large rice surplus throughout the country. This abil- ity of all regions to produce their own food and the general uniformity of resources throughout the country led to a situation of minimal trade relations within the kingdom itself. Internal in- frastructure such as roads, bridges, and canals was never attended to, and there was little need for ordinary Khmers from different regions to communicate with one another. Instead all interactions moved up and down the social hi- erarchy. Externally Khmer royalty purchased gold, silk, porcelain, lacquerware, umbrellas, and other luxury goods from China and India, in turn trading beeswax, bird feathers, rhinoc- eros horn, and other tropical forest products.'§REF§(West 397)§REF§"
