Bound entanglement, being entangled yet not distillable, is essential to our understanding of the relation between nonlocality and entanglement besides its applications in certain quantum information tasks. Recently, bound entangled states that violate a Bell inequality have been constructed for a two-qutrit system, disproving a conjecture by Peres that bound entanglement is local.  In this talk, we give a brief review and then present a family of new nonlocal bound entangled states for all finite dimensions larger than two, making possible their experimental demonstrations on most general systems.  The talk is based on the paper
