For values the definition i have is: The core beliefs of an individual or country.
for beliefs: The values within a country that have widespread acceptance.
Now, do those definitions seem kinda dodgy or what?
these are probably a bit dodgy..but could possibly give you a better idea at least..
values: the core beliefs of an individual or country; important understandings that form the basis of shared behaviour of an individual or cultural group
beliefs: principles accepted and shared among a group of people; indicate a particular way of perceiving the physical world and the universe
