In this paper, we consider nonlinear mixed vector variational inequality problems in the setting of topological vector spaces. We extend the concept of upper sign continuity for vector-valued functions and establish some existence results for solutions of vector variational inequalities. By utilizing a new version of Ky Fan lemma we investigated the nonemptyness and compactness of solution sets of these problems under some suitable assumptions.
