The library has a guide to information resources on countries. To get to it, go to the library's home page. Then select the blue tab above the Libsearch search box that says Research Guides. Click on the Business link, then select "International Business" from the list of guides that comes up. Once you're in there, select the Country Resources tab. The direct link to this page is http://library.uhd.edu/internationalbusiness
A to Z World Business has reports on each country. When you get into the database scroll down a little bit and on the left side of the page you will see "Country Business Guides." Select Cambodia from the list and you will find lots of information about Cambodia and doing business there.
Other possibly useful resources on the country page are CIA World Factbook, which gives statistics, and Country Reports on Human Rights Practices, which tells you some about labor and human rights issues.
