  Suppose that X is a nonsingular variety and D is a nonsingular proper
subvariety. Configuration spaces of distinct and non-distinct n points in X
away from D were constructed by the author and B. Kim in arXiv:0806.3819, by
using the method of wonderful compactification. In this paper, we give an
explicit presentation of Chow motives and Chow rings of these configuration
spaces.
