  In this paper we apply Rieffel deformation to C*- tensor product viewed as a
functor on the category of C*-algebras with an abelian group action. In the
case of the Rieffel deformation of a quantum group with the action by
automorphisms the deformed tensor product enables us to view the deformed
object as a braided quantum group. We construct a bicharacter for a braided
quantum group and the dual braided quantum group. We employ our method to get a
braided quantum Minkowski space. Its description in terms of the deformed
space-time coordinates is provided.
